New York Mets right-hander Taijuan Walker was scratched from Sunday’s start in Philadelphia due to a back injury.

The team did not immediately name a replacement for the afternoon game against the host Phillies.

Walker was removed from Tuesday’s start at Atlanta after allowing one hit and walking two batters in two scoreless innings. He sustained back spasms after running to cover first base on a ground ball.

Walker, 30, is 10-3 with a 3.36 ERA in 21 starts this season. He has struck out 85 batters in 112 1/3 innings.

Mets manager Buck Showalter said Saturday that Walker could return to the rotation on Tuesday against the New York Yankees.

An All-Star in his first season with New York in 2021, Walker is 52-48 with a 3.89 ERA in 159 games (155 starts) over 10 seasons with the Seattle Mariners, Arizona Diamondbacks, Toronto Blue Jays and Mets.
