St. Louis Cardinals pitching prospect Quinn Mathews got one start for St. Louis this season before being called back down to Triple-A Memphis. In two starts back with Memphis, Mathews has allowed four earned runs in seven innings pitched with nine combined strikeouts in the two starts. In his lone big-league start, Mathews took a hard-luck loss to the Toronto Blue Jays with two earned runs in five innings pitched. Mathews has looked sharp all year long in the minors for Memphis and the left-hander is the No. 8 prospect for St. Louis with a 60-grade slider and changeup in his four-pitch mix. The Cardinals rotation is very young so Mathews will look for another shot at the MLB level. He is worth holding onto in redraft leagues because he does have good strikeout potential with a strong four-pitch arsenal.

New York Yankees manager Aaron Boone said on Sunday that outfielder Cody Bellinger (hamstring) is scheduled to play in minor-league rehab games on Tuesday and Thursday, likely with Triple-A Scranton/Wilkes-Barre, and he could be activated from the 10-day injured list by next weekend, according to Erik Boland of Newsday Sports. The Yankees are desperate for more offense, so Bellinger will be a welcome addition to the lineup with both Aaron Judge (rib) and Giancarlo Stanton (calf) still on the shelf. Although the 31-year-old veteran left-handed slugger hasn't been nearly as good as he was in his first year in the Bronx in 2025, Bellinger still can be a difference-maker for fantasy managers down the stretch with his bat, which is why he's still rostered in 95% of Yahoo leagues. When he returns from the IL, Bellinger will be coming back to a .259/.350/.420 slash line with a .770 OPS, 11 home runs, 53 RBI, 10 stolen bases, and 52 runs scored in his 102 games and 434 plate appearances. The three-time All-Star belted 29 homers and drove in 98 runs in 152 regular-season games last year with New York.

In nine games with his new squad, the Triple-A Jacksonville Jumbo Shrimp, Miami Marlins prospect Jonathon Long is 9-for-25 (.360) at the plate with three RBI and 11 runs scored. The right-handed hitting third base/first base prospect was traded from the Chicago Cubs organization to the Marlins. He started at Triple-A Iowa with 12 homers and 62 RBI in 99 games with a .283 average and 67 runs scored. Long slots in at the No. 19 prospect in the Marlins system but he might have a clearer path to the majors than he did with the Cubs. The Marlins are playing Javier Sanoja at third base and now have Kyle Stowers on the IL at first base. So there looks to be an opportunity for Long to make his big-league debut. If he does, he would be a solid bat for fantasy managers down the stretch.

Seattle Mariners middle-infield prospect Michael Arroyo has fared well at Triple-A Tacoma since his promotion and could be next in line for a call-up to Seattle, following in the footsteps of Tacoma teammate Brock Rodden. Arroyo has played in 31 games for Tacoma this season and has six homers and 27 RBI while hitting .295. Arroyo, the right-handed hitter out of Colombia, is the No. 3 prospect on the Mariners list. The infielder has a balanced profile with a 55-grade hit tool and power with 50-grade speed. At age 21, he could be ready for his next step to the majors but might need a little more time at Triple-A. Nonetheless, he is looking like a good stash candidate and one that could reward fantasy managers with five-category production given an opportunity to make his MLB debut.

Texas Rangers right-hander Jacob deGrom (triceps) got favorable results from an MRI exam on a right-triceps injury that forced him from his last start on Thursday against the division-rival Los Angeles Angels, according to Theo DeRosa of MLB.com. However, manager Skip Schumaker wasn't overly optimistic when asked about deGrom's chances to start on time against the Washington Nationals at Globe Life Field on Wednesday. "I guess it's possible," Schumaker said. "I don't know how realistic it is, but I think it's always possible. We haven't ruled it out completely." After missing nearly all of 2023 and 2024 after having Tommy John surgery, deGrom hasn't needed a stint on the injured list since. He was an All-Star in 2025 and has posted a 3.95 ERA in 23 starts in 2026. The 15-year veteran felt better on Saturday, but he has yet to resume playing catch, which makes it more unlikely he will start on Wednesday. deGrom is still rostered in almost 100% of Yahoo leagues, but he'll be riskier as a fantasy starter whenever he toes the rubber again.

Minnesota Twins top prospect Walker Jenkins has had a red-hot month of August at Triple-A St. Paul and is looking like the next call-up prospect for the Twins after Kaelen Culpepper. Jenkins is hitting .381 this month with three homers and five RBI in 42 at bats. That has raised his overall batting average between three minor league levels to .306 this season with nine homers and 23 RBI in 65 at bats. The left-handed hitting stud prospect missed a large amount of time this season with a Grade 2 AC joint sprain in his left shoulder. But now that he is back, he is one of the top hitting prospects to stash in redraft leagues for the rest of the season. It is likely he will join Culpepper in getting a shot an MLB debut and when he does he will showcase his 60-grade hit tool and 60-grade power.

Philadelphia Phillies shortstop Trea Turner (knee) is out of the team's starting lineup for Sunday's series finale in Minnesota against the Twins, according to MLB.com. Turner fouled a ball off himself in Saturday's contest against the Twins and is dealing with a right-knee/ankle contusion. The good news is that he didn't require any X-rays following Saturday's game and appeared to be walking around fine in the clubhouse. The veteran shortstop expects to be fine and should be back in action for Monday's series opener at home against the division-rival Miami Marlins. Edmundo Sosa will start at the 6 on Sunday and will bat ninth against Twins right-hander Dean Kremer. Turner is currently slashing .247/.298/.398 with a .696 OPS, 17 home runs, 47 RBI, 17 stolen bases, and 82 runs scored in 120 games played across 533 plate appearances in 2026 in his 12th year in the big leagues. The three-time All-Star still has decent pop, but he's not running nearly as much and has shown plenty of signs of offensive decline as he nears the back end of his career.

Arizona Diamondbacks second baseman Ketel Marte (knee) is starting at second base and batting cleanup for the Snakes in Sunday's series finale in Atlanta against Braves right-hander Bryce Elder, according to D-backs reporter Jody Jackson. Marte was pulled from Friday's win over Atlanta with some knee soreness, and he was held out of Saturday's win as a precaution. He's back in the starting nine for the series finale and should be returned to all traditional starting fantasy lineups, even if he doesn't have a great history against Elder. In just seven career at-bats against Elder, Marte is hitting .143 with two RBI. The 32-year-old three-time All-Star and two-time Silver Slugger winner is hitting .251/.315/.448 with a .763 OPS, 21 home runs, 67 RBI, 64 runs scored, and four stolen bases across 117 games and 515 plate appearances. So far in August, he's gone 9-for-40 (.225) with an .805 OPS, two home runs, two doubles, five RBI, six runs scored, eight walks, and eight strikeouts.

Pittsburgh Pirates ace Paul Skenes will have his scheduled start on Sunday pushed back to Wednesday, according to Jason Mackey of SportsNet Pittsburgh. Per Mackey, this move is due to concerns about his recovery and is not injury-related. The team is looking to provide the former top prospect with additional time to recover between starts. This is quite noteworthy as Skenes has endured some struggles over the past month of action. In his most recent outing, he tossed just five innings and threw only 65 pitches. The most notable concern of this start was that his fastball averaged a career-low of 95.7 MPH in this game. This season, Skenes has posted a 3.88 ERA and a 1.12 WHIP, a massive jump from last season's 1.97 ERA. Managers should continue to monitor his status in case Skenes faces further workload limitations down the stretch.

Philadelphia Phillies shortstop Trea Turner (knee) left early during Saturday's game against the Minnesota Twins. Turner exited the game after fouling a pitch off his right knee, according to Scott Lauber of The Philadelphia Inquirer. He was removed from the game in the eighth inning with the Phillies already leading big. The team was likely just being cautious, especially with a big lead on the scoreboard late in the contest. Before leaving, Turner went 1-for-3 with a single, a run scored, and a walk. Justin Crawford replaced him in the lineup while Edmundo Sosa took over at shortstop. Fantasy managers should check back after the game for another update on his injury.

Boston Red Sox outfielder Roman Anthony (finger) is set to begin a rehab assignment with Double-A Portland on Tuesday, according to Sean McAdam of MassLive.com. It appears that Anthony is finally making progress with his finger injury that has kept him sidelined since early May. He has been rehabbing a partially torn tendon in his finger, but appears ready for game action. Given he hasn't played in months, Anthony will likely require a lengthy rehab assignment. He should return by the end of the month, but will likely require at least a week of rehab games. Fantasy managers should check back for an update on his status over the next week.

San Francisco Giants starting pitcher Logan Webb (back) was forced to make an early exit from Saturday's outing against the Colorado Rockies. Webb was pulled after 80 pitches due to back and shoulder tightness, according to Justice delos Santos of The San Jose Mercury News. Webb threw six strong innings, but began to feel tightness in his shoulder after getting hit by a comebacker in the fifth inning. The Giants decided to remove him from the contest as a precaution. Before exiting, Webb allowed one earned run on four hits while striking out seven batters across six innings of work. He's tentatively scheduled to pitch against the Boston Red Sox next week. Fantasy managers should check back in the coming days for an update on his status.

St. Louis Cardinals outfielder Joshua Baez made history during his big league debut against the Chicago Cubs on Saturday. Baez did something no other MLB player has done before, which is homer in his first three plate appearances. He took the first pitch he saw as a big leaguer deep to center field for a solo homer off Matthew Boyd. He continued his success off Boyd with another long ball in the fourth inning. Baez came up for his third plate appearance in the sixth inning and blasted a ball over the right field wall. Overall, Baez went 3-for-4 with three homers and five RBI in his debut. The power and speed potential make Baez worth snagging in all fantasy formats right now after his incredible MLB debut.
