Philadelphia Phillies right-handed pitching prospect Moises Chace (elbow) is set to undergo Tommy John surgery. The 21-year-old is currently ranked as the No. 5 prospect in the system on MLB.com. Through the opening month of the regular season, Chace logged 16 2/3 innings at Double-A. Through this stint, Chase held a 3.24 ERA with a 1.62 WHIP. He struck out 19 batters but struggled to command his pitches as he served up 16 free passes. Last season, Chace logged 60 2/3 innings between High-A and Double-A and posted an overall 3.56 ERA with a 1.25 WHIP. Fantasy managers should expect Chace to remain sidelined through at least the first half of the 2026 season. When he does return, the Phillies will likely keep him at Double-A given his early-season struggles.

Philadelphia Phillies pitching prospect Moises Chace is expected to be on a slower progression during camp. The right-handed pitcher did not have many opportunities to throw in Venezuela during the winter and did not come into camp "in the best shape." The 21-year-old has yet to face live batters and may not do so for a few weeks. Last summer, Chace made his High-A debut with the Aberdeen IronBirds. He tossed 52 innings and held a 3.46 ERA and a 1.29 WHIP. He was deployed both out of the rotation and from the bullpen. He was then shipped to Philadelphia, where he had a brief stint with their High-A affiliate before moving up to Double-A. With Double-A Reading, Chase was given four starts (19 2/3 innings) and posted a 3.66 ERA and a 1.07 WHIP. He tallied an impressive 35 punchouts with just seven walks. Dynasty managers should expect Chase to open the season at Double-A and should push for a Triple-A debut later in the summer.
