The Philadelphia Phillies have moved struggling starting pitcher Taijuan Walker to the bullpen, a decision that comes as the team battles for the NL East title. Walker, who signed a four-year, $72 million deal before the season, has a 6.50 ERA this season, including a 9.17 ERA in his last four starts. The Phillies hope that the move will allow Walker to regain his form as a long reliever, providing valuable innings in a tight race for the division lead. The team is currently holding onto a slim lead over the Atlanta Braves, their rivals in the NL East.
