Mick Abel has emerged as a must-have fantasy pickup after striking out 31.4% of batters in his last two starts. The Twins right-hander's improved mechanical tweaks have led to better extension and a .182 batting average against his changeup, making him a valuable option for Week 4 matchups against the Mets and Rays.

San Diego Padres hitters deserve consideration with their Week 4 schedule featuring games at Coors Field and Mexico City's Estadio Alfredo Harp Helú. Spencer Arrighetti (Astros) and Jeremiah Jackson (Orioles) also present intriguing options, with Jackson bringing eligibility at three positions including the thin 2B spot.

For deeper leagues, consider Brad Keller (Phillies) who could see save opportunities with Duran injured, and Enyel De Los Santos (Astros) who has posted a 1.17 ERA and two saves recently. The Astros' bullpen situation remains unsettled with Hader on the IL, creating potential fantasy value for savvy managers.
