Walker (knee) is slated to pitch behind starter David Peterson in Saturday's Grapefruit League game against the Nationals, Anthony DiComo of MLB.com reports.
Walker will finally be making his spring debut this weekend after a mid-January procedure on his right knee had kept him about two weeks behind the Mets' other starting pitchers thus far in camp. Though the right-hander hasn't said whether he plans to be ready to go for Opening Day, how long he works and how he fares in Saturday's contest will likely be a deciding factor. Walker earned his first All-Star nod in his first season with the Mets in 2021, but he faded badly in the second half to finish with a 4.47 ERA, 1.18 WHIP and 146:55 K:BB in 159 frames.
