New York Yankees' ace Gerrit Cole has been scratched from his scheduled start against the Philadelphia Phillies due to general body fatigue, which he attributes to hitting his max pitch capacity three times in a row. Cole has struggled this season with a 5.40 ERA over seven starts after missing the first half due to an elbow injury. Rookie Will Warren will make his MLB debut in Cole's place. Despite Cole's absence, the Yankees won Game 1 against the Phillies, but significant challenges remain. Yankees manager Aaron Boone mentioned Cole has also been dealing with a stomach bug and expects him to pitch this weekend against the Blue Jays. Fans and analysts express concern over the Yankees' rotation stability amid trade deadline speculations.
