Seattle Mariners second base/outfield prospect Michael Arroyo was recently promoted from Double-A Arkansas to Triple-A Tacoma and is producing with two homers and 13 RBI in just 12 games with Tacoma. Altogether in the month of July, between the two levels, Arroyo is hitting .395 with four homers, 19 RBI, and 19 runs scored. Arroyo, the No. 5 prospect in the Mariners' system, can play second base or outfield, so he offers some positional flexibility for a potential call-up to Seattle. The Mariners are well stocked at the big league level with Cole Young manning second base and boast a loaded outfield. But Arroyo, the talented right-handed hitter out of Colombia, is producing in his age-21 season, and fantasy managers would be wise to add the talented youngster whose 55-power and 55-hit tool could be on display before the end of the season.

Washington Nationals corner-infield prospect Yohandy Morales continues to hit for power at Triple-A Rochester and is making a case for a potential promotion. The No. 26 overall prospect for the Nationals, Morales has been consistently producing all season at Triple-A with 21 homers, 62 RBI, and 66 runs scored with a .294 batting average. The numbers beg the question if Morales deserves a shot with the Nationals, a team with a lineup loaded with young talent. Morales was a second-round pick in the 2023 MLB Draft, and his 55-grade power makes him an option as he can play either corner infield position. Morales could be worth a look in deep leagues as a sleeper stash, as his power bat would be a welcome addition to a deep Washington lineup at the big-league level.

Colorado Rockies first baseman TJ Rumfield has been one of the breakout success stories of the 2026 season, hitting .297/.381/.476 with 13 home runs, 52 RBI, and 45 runs scored across 409 plate appearances. The 26-year-old's underlying batted-ball metrics are underwhelming, as he's logged just a 5.3% barrel rate and a 28.2% hard-hit rate. However, Rumfield has struck out in just 14.2% of his plate appearances on the year. Between his propensity to put the ball in play and his hitter-friendly home environment in Colorado, Rumfield profiles as one of the safer sources of batting average and run production available to fantasy managers on the waiver wire.

Cleveland Guardians infield prospect Angel Genao is tearing up the International League at Triple-A Columbus during the month of July with a .426 batting average, two homers, nine RBI, and 12 runs scored. The No. 2 prospect in the Guardians' system, Genao has split time this year between Double-A Akron and Columbus with a combined .296 batting average and 11 homers with 44 RBI and 60 runs scored. With Travis Bazzana manning second base at the major league level and with Brayan Rocchio at shortstop, Genao is blocked a bit by talent at the major league level, but he continues to produce at Triple-A. He is looking like a nice addition even in shallow leagues as he is likely to make his big league debut at some point this season. When he does, his 60-grade hit tool should make him a mainstay in fantasy lineups down the stretch.

Since being called up for his MLB debut in mid-May, New York Mets outfielder A.J. Ewing is hitting .274/.345/.426 with seven home runs, 25 RBI, 27 runs scored, and 11 stolen bases across 251 plate appearances. The 21-year-old has struck out in 27.1% of his plate appearances, which is a bit of a concern for fantasy managers. However, Ewing owns elite speed, which allowed him to consistently run a high batting average on balls in play throughout his time in the minor leagues. Across 124 minor league games in 2025, Ewing hit .392 on balls in play and stole 70 bases. Ewing has also drawn walks in 9.6% of his big league plate appearances, which should continue to help him make an impact on the bases. In leagues where he's not already rostered, fantasy managers should target Ewing as a speed threat with upside on the waiver wire.

In his last five games for Triple-A Scranton/Wilkes-Barre, New York Yankees prospect George Lombard Jr. has nine hits and a home run and he homered twice in his rehab assignment with the FCL Yankees in the two game prior. To say the Yankees top overall prospect has been red hot would be an understatement. His hot streak makes the shouts louder and louder from Yankees fans for a promotion, but nothing is official as of this moment. Fantasy managers, however, would be wise to add the 21-year-old now. Lombard Jr. is a five-tool prospect and has put up good numbers between three minor league teams this season. He has 11 homers and 29 RBI in 253 at bats with 12 stolen bases all while hitting .281. He has 55-grade power and 55-grade speed, so he could be looked to for elite numbers in the power categories all while contributing to the stolen base category as well. Now is the time to add the youngster.

Across 410 plate appearances in 2026, Houston Astros infielder Isaac Paredes is hitting .263/.354/.438 with 14 home runs, 54 RBI, and 42 runs scored. The 27-year-old's overall line is solid, but he's really started to heat up in July. Across 71 plate appearances so far this month, Paredes is hitting .323 with three homers and nine RBI. Paredes has never had elite batted-ball metrics, and he's posted subpar barrel (6.1%) and hard-hit (30.4%) rates once again this season. However, the righty slugger maximizes his power by pulling the ball in the air at a high rate, which is a perfect approach for Houston's short left field. Paredes is also tough to strike out (15.1% strikeout rate), which helps keep his batting average floor high. For fantasy managers in need of power and run production, Paredes is a logical waiver-wire target.

Across 443 plate appearances this season, Detroit Tigers shortstop/third baseman Kevin McGonigle is hitting .281/.388/.422 with nine home runs, 35 RBI, 61 runs scored, and 11 stolen bases. The 21-year-old does not profile as a significant value-add in the power categories for fantasy managers, as he owns just a 7.6% barrel rate and a 38% hard-hit rate. However, McGonigle offers an elite plate approach, especially for a rookie. He's logged a 14.2% walk rate while striking out in just 13.8% of his plate appearances. McGonigle's ability to get on base has allowed him to cement himself as the near-everyday leadoff hitter in Detroit, which should keep him near the top of the runs-scored leaderboard for the rest of 2026. He also offers managers quality production in the batting average and speed categories. If McGonigle can hit for even slightly more power in the final few months of the season, he could emerge as a true five-category contributor.

Colorado Rockies first base/outfield prospect Charlie Condon is hitting .306 in July and is looking day by day like a potential call-up to make his major-league debut. Condon, the former No. 3 overall pick in the MLB Draft, is tearing up Triple-A Albuquerque this season, hitting .289 with 20 homers, 62 RBI, 77 runs scored with six steals, and a .975 OPS. The No. 3 overall prospect for the Rockies, Condon is looking like a must-add in all formats as he continues to light up the Pacific Coast League. The 23-year-old right-handed hitter is looking like a player who can pay back fantasy managers who take a chance and stash him on their roster. Condon can play first base or outfield, so he offers some roster flexibility to the Rockies should they want to call him up to make his major league debut. He is looking like one of the top adds on the waiver wire even though he is still in Triple-A. He looks like a difference-maker in the second half.

Across 116 1/3 innings (20 starts) in 2026, Pittsburgh Pirates starting pitcher Braxton Ashcraft has recorded a 9-4 record with a 3.95 ERA, 1.17 WHIP, and 130 strikeouts. While Ashcraft's overall line is strong, he's run into a rough patch of late. Across his last two starts, the 26-year-old has allowed four home runs and 12 earned runs in just eight innings pitched. Ashcraft's previous career-high for innings pitched in a professional season was 73 in 2024, so he may be running into a wall under the strain of his current workload. However, the young right-hander's underlying metrics still point to high-end upside. Ashcraft is averaging 97.2 miles per hour on his fastball, and he's logged a 27.0% strikeout rate with just a 5.8% walk rate. In leagues where managers are panicking after back-to-back rough outings, Ashcraft could be worth buying low on.

The Baltimore Orioles announced on Friday that first base/outfield prospect Ike Irish (knee) is being placed on the High-A Frederick seven-day injured list due to a torn left meniscus that he suffered while sliding into second base on Wednesday, according to Steve Malewski. Irish, the Orioles' No. 2-ranked prospect per MLB Pipeline, is likely to miss the rest of the season. The 22-year-old former 19th overall pick out of Auburn University in 2025 will have his first full pro season cut short after hitting .286/.388/.528 with a .915 OPS, 16 home runs, 59 RBI, 20 stolen bases, and 62 runs scored in 76 games across 343 plate appearances at Frederick. It ends a fantastic season for Irish in the lower levels of the minors. He should be ready to play for the start of the 2027 campaign, where he'll likely begin at Double-A Chesapeake. The 6-foot-2, 201-pound left-handed hitter has a mature approach at the dish and hits the ball hard to all parts of the field. There's a lot to like about Irish, who can hit for average and provide plenty of speed. The jury is still out on his overall power ceiling, but there is at least 20-homer potential.

Minnesota Twins outfield prospect Walker Jenkins has returned to the lineup for Triple-A St. Paul and has now been back for about a month. Activated on June 23, Jenkins has a month full of production under his name with modest results. The Twins top overall prospect has two homers and six RBI to his name during the end of June and most of July. Jenkins, a left-handed hitting former first round pick is uber-talented but is finding his swing after suffering a Grade 2 AC joint sprain in hi left shoulder. As he works his way back, now might be a good time to add Jenkins in dynasty leagues especially but also in shallow redraft leagues. In 168 at bats for St. Paul this year, Jenkins has recorded four homers and 15 RBI while hitting .274. He still has the tools to be successful in a call up to Minnesota and the Twins still could act on the 21-year-old sometime during the second half. Right now getting back to full health is the main priority for Jenkins.

Cleveland Guardians left-hander Parker Messick has been one of the breakout success stories of the 2026 season so far. Across 117 2/3 innings (20 starts), the 25-year-old has recorded an 8-5 record with a 2.68 ERA, 1.05 WHIP, and 116 strikeouts. Messick has been particularly effective so far in July, allowing one earned run or fewer in all three of his starts this month. With an average fastball velocity of 93.9 miles per hour and a 24.8% strikeout rate, Messick may not have true fantasy SP1 upside. However, he does an excellent job of limiting hard contact. Opposing batters have posted just a 5.4% barrel rate against Messick, and he's allowed 0.84 HR/9. The young left-hander may be in for some slight regression in the second half of the season, but he profiles as a clear must-start pitcher for fantasy managers going forward.

Arizona Diamondbacks manager Torey Lovullo said on MLB Network Radio that second baseman Ketel Marte (back) will be back in the starting lineup for Friday's series opener against the hosting Washington Nationals and left-hander Carson Palmquist after he was scratched from Thursday's series finale against the St. Louis Cardinals with back stiffness, according to Dani Wexelman. Even with a left-hander on the mound to start for Washington, the 32-year-old switch-hitting Marte should be started in fantasy. In 115 plate appearances against southpaws as a right-handed hitter in 2026, Marte has hit .305 with eight of his 18 homers on the year. Marte has hit just .229 (16-for-70) with a homer, three doubles, a triple, six RBI, nine runs scored, three steals, five walks, and 15 strikeouts in 17 games and 76 plate appearances during July, but he's a must-start in most traditional fantasy formats at the keystone when he's active for his power from both sides of the plate.

Detroit Tigers right-hander Casey Mize (groin, wrist) will start on Saturday against the division-rival Kansas City Royals at Comerica Park, according to MLB.com. Mize was hit by a comebacker on his left wrist and aggravated a groin injury in his last start on Sunday against the Los Angeles Angels, but the two injuries weren't enough to keep him from going this weekend in Motown in a plus matchup. He was able to throw his normal between-starts bullpen session this week and is ready to roll, so fantasy managers should get ready to throw him back into their starting lineups. The 29-year-old former first overall pick in 2018 out of Auburn has had a career year in 2026, going 4-6 with a 2.79 ERA (2.62 FIP) and 1.03 WHIP with 82 strikeouts and 19 walks in 80 2/3 frames across his 15 starts. Mize has dealt with some injuries and spent time on the injured list, but when available, he's been great, and he also has a career-best 25.6% strikeout rate. He hasn't allowed more than three earned runs in any of his last four starts.

Miami Marlins right-hander Eury Perez's overall numbers in 2026 in his third year in the majors don't jump off the page, as he's gone 5-7 with a 3.53 ERA (4.12 FIP) and 1.11 WHIP with 104 strikeouts and 37 walks in 91 2/3 innings pitched across his 17 starts for the Fish. But the 23-year-old Dominican has been pretty dominant in his last seven outings since he allowed a season-high five earned runs with four walks in five innings in a loss to the Tampa Bay Rays on May 17. In his seven starts since then (39 1/3 innings), Perez has given up just five earned runs on 19 hits (three homers) while walking nine and striking out 46 for a 1.14 ERA (2.67 FIP). His most recent outing on July 19 against the Milwaukee Brewers might have been the most impressive, as he generated 17 swings and misses while throwing six scoreless innings with three walks and nine punchouts. Although Perez's expected ERA sits at 4.05, fantasy managers should continue to ride him into his next scheduled start in an excellent matchup against the punchless San Diego Padres' lineup.

Seattle Mariners outfielder Randy Arozarena has hit a strong .281 (97-for-345) in his second year with the team on his way to his third All-Star appearance, but his power has been down in 2026, and his underlying metrics don't exactly project a strong finish. The 31-year-old Cuban finished the first half on a good note and went into the All-Star break with a .286/.380/.458 slash line and an .838 OPS in 89 games and 379 plate appearances. He hit only two home runs in June, though, and he's currently batting .273 (15-for-55) with an .883 OPS, three homers, a double, eight RBI, and 12 runs scored in 16 games in the month of July. Under the hood, Arozarena has a .264 expected batting average and .352 xwOBA (.365 current wOBA), suggesting regression to close out his eighth year in the big leagues. He also has a hard-hit rate in the 54th percentile and ranks in the 47th percentile in barrel rate, the 40th percentile in chase rate, and the 58th percentile in expected slugging. Arozarena can get hot in an instant, but he can also be streaky, and although he's making more contact this year, his quality of contact is down.

Athletics shortstop Jacob Wilson has dealt with injuries in his second full season in the big leagues and still has very little power (seven homers) at a premium position, but he still makes a lot of contact at the plate and is hitting .291 (73-for-251) on the season in his 62 games across 265 plate appearances. The 24-year-old former sixth overall pick from Grand Canyon University is gaining steam in July for fantasy managers who are looking for a boost in the average department. Wilson will carry a 10-game hitting streak into the weekend. During his streak, he's gone 17-for-42 (.405) with three home runs, a triple, six RBI, seven runs scored, and a stolen base in 43 plate appearances to boost his overall slash line in 2026 to .291/.322/.422 with a .744 OPS. We're tempering expectations for the rest of the second half because of his .293 xwOBA (wOBA of .325) and his .273 expected batting average, but while he's hot in July, fantasy managers are jumping on board.

Miami Marlins right-handed reliever Michael Petersen has become a top stash candidate off the waiver wire for fantasy managers who are speculating on saves in the second half amid current closer Pete Fairbanks' struggles. Fairbanks leads the Fish with 13 saves on the season, but he also has an ERA over 7.00, a 1.52 WHIP, and a 10.1% walk rate. He blew his latest save chance on July 19 against the Milwaukee Brewers, allowing three earned runs with a walk and a strikeout in just one-third of an inning, and he has now given up 11 runs (10 earned) on 14 hits (four homers) with three walks and 10 K's for two saves and a blown save in his last 8 1/3 innings pitched since June 23. With the Marlins flailing of late, they could make a change in the ninth inning, and if they do, Petersen appears to be next in line. The 32-year-old English native has a 2.91 ERA (3.27 FIP), 0.99 WHIP, his first career save, 51 strikeouts, and 17 walks in 43 1/3 innings in 2026 in his first full year in Miami. At the very least, Petersen is valuable in holds leagues with 17 on the year. So far in seven innings in July, he's allowed just one earned run with four walks, seven K's, and four holds. Petersen is rostered in just under 10% of Yahoo leagues.

New York Mets outfielder Carson Benge has quietly been one of the more productive rookie bats in 2026 for the last-place Mets. Going into the weekend, he is slashing .263/.324/.397 with a .720 OPS, 11 home runs, 13 doubles, 40 RBI, 16 stolen bases, and 52 runs scored as a lineup regular through 99 games and 408 plate appearances in his first year in the big leagues. The return of Luis Robert Jr. from the injured list recently has made New York's outfield a bit more crowded, but the 23-year-old former 19th overall pick from Oklahoma State University in 2024 has earned consistent playing time the rest of the way in what has become a lost season for the Mets. Benge can contribute across the board for fantasy managers and has stayed hot in 16 games in July, going 18-for-61 (.295) with an .805 OPS, two home runs, three doubles, eight RBI, five stolen bases, and eight runs scored across his 69 plate appearances. Fantasy managers are slowly catching on, but Benge is still rostered in just over half of Yahoo leagues, so he remains widely available.
