Seattle Mariners starting pitcher Kade Anderson was called up to make his MLB debut two weeks ago. His three starts since the call-up haven't been otherworldly, but he still has the strikeout upside necessary to make him an impactful starting pitcher in fantasy baseball for the final stretch of the season. Anderson has a 5.40 ERA through his three starts, but the 3.17 FIP doesn't look quite as bad. The ball-in-play metrics are solid, but we'd like to see him harness his strikeout, walk, and home run rates over a larger sample size. His 6.60 K/9 rate in the majors is essentially half of his rate from the minors this year, and his 4.20 BB/9 and 1.80 HR/9 rates are both key reasons why his ERA is so high. Getting called up midseason could be the main reason why Anderson has been a little shaky in the majors, and we have no concerns about his ability to produce long-term. Meanwhile, in the short-term, there's still a window for him to turn things around if he can attack the strike zone and miss more bats. He's an intriguing stash in September because if he makes those corrections, he'll have a huge fantasy baseball impact. He currently ranks as the #30 starter in RotoBaller's latest rest-of-season fantasy baseball rankings.

Pittsburgh Pirates outfield prospect Edward Florentino homered on Saturday for his second homer in four games with High-A Greensboro. Florentino has had a good minor league season at age 19 between two minor league levels, combining to hit .236 with 27 homers and 84 RBI with 84 runs scored and 11 stolen bases. The left-handed hitter is the No. 2 prospect in the Pirates system with a 50-grade hit tool, 60-grade power, and 55-grade speed. At 6-foot-3 and 200 pounds, Florentino is a bit wiry but has room to put on some more muscle, which will only likely add to his power. His average is a bit low this season, but that could be due to adjusting to the minors in only his third professional season. Signed out of the Dominican Republic, Florentino looks to have high fantasy upside and be a high priority dynasty league pickup.

Philadelphia Phillies shortstop prospect Aidan Miller made his season debut on a rehab assignment with Single-A Clearwater on Saturday. The 22-year-old was 1-for-2 at the plate in his debut with a run scored. Miller returned to action on a rehab assignment for his back injury. The right-handed hitter is the No. 2 prospect in the Phillies system and has a well-rounded game with a 55-grade hit tool, 60-grade power, and 50-grade speed. The Phillies first round pick in the 2023 MLB draft out of a Florida high school, Miller has good size at 6-foot-1 and 205 pounds and made it all the way to Triple-A during the 2025 season. With a chance to get some games under his belt at the end of this season, Miller looks to be a solid dynasty league target. He promises to be one of the up and coming players at the shortstop position.

Minnesota Twins prospect Emmanuel Rodriguez is hitting for power in his limited action at Triple-A St. Paul this season. In 45 games at Triple-A, Rodriguez has 11 homers and 31 RBI but is hitting just .252. Rodriguez has battled a bad thumb injury this season which has limited his game time but the power in his bat has shown. The 23-year-old left-handed hitter is the No. 5 prospect in the Twins system and has a 45-grade hit tool with 55-grade power and speed. Rodriguez also has seven stolen bases in his little game time this season. Rodriguez has some work to do on his overall hitting and is a batting average risk for fantasy but his power-speed combination is real. The Twins have already called up top prospects Walker Jenkins and Kaelen Culpepper so they might elect to keep Rodriguez in the minors the rest of this season. but if they do look his way for a promotion he could have some late impact on the fantasy season.
