Identifying pitching sleepers for the upcoming baseball season can offer a significant advantage in fantasy leagues. A.J. Puk is emerging as a hidden gem for Arizona, boasting an impressive statistical profile that includes a 1.72 ERA and a SIERA of 2.16. Grant Holmes of the Braves, with a strong strikeout-to-walk ratio, is set to benefit from a potent Atlanta lineup. Meanwhile, Nick Lodolo’s potential to rebound after an injury makes him an enticing option for Cincinnati. Spencer Arrighetti of the Astros is a notable sleeper, showing promise with a solid CSW rate, while Jesús Tinoco may unseat Calvin Faucher as Miami's closer. Lastly, keep an eye on Clay Holmes with the Mets and Clarke Schmidt with the Yankees; both have compelling cases to be fantasy mainstays this season.
