Taijuan Walker's disappointing 2024 season has led to his demotion from the Phillies' starting rotation to the bullpen after struggling with a 6.50 ERA over 14 starts, including a 9.17 ERA in his last four games. He has not won since May and was recently tagged for six runs in a loss to the Astros, prompting manager Rob Thomson to make the change. Walker, who signed a four-year, $72 million contract prior to the season, recognizes the need for improvement and hopes to adapt to a relief role despite limited experience, having last pitched out of the bullpen in 2014. The Phillies, currently pursuing an NL East title, aim for Walker to increase his velocity and effectiveness in the bullpen. Speculation about Walker's future looms, as he faces the possibility of being designated for assignment given his struggles and hefty contract. Thomson expressed empathy for Walker's situation, emphasizing his hard work and the hope for a turnaround.
