As we approach Week 10 of the 2025 MLB season, several pitching prospects are emerging as must-adds for fantasy baseball enthusiasts. Bubba Chandler of the Pittsburgh Pirates is a standout, having posted five hitless innings with eight strikeouts in his last start, showcasing a 2.03 ERA this season in Triple-A. In Philadelphia, Andrew Painter is making strides after returning from Tommy John surgery, recording solid outings at Triple-A. Jacob Misiorowski from the Milwaukee Brewers has impressed with a 2.04 ERA over 39.2 innings, making him a prime candidate for MLB promotion soon.

Ian Seymour of the Tampa Bay Rays brings elite strikeout potential, and Mick Abel, also from the Phillies, has been called up to fill a rotation spot. Each of these pitchers exhibits significant upside, making them worthy stashes as teams look to bolster their pitching depth. Stashing them now could provide valuable edge down the stretch.
