4:55pm: McWilliams and Tarpley are on the COVID list, Healey tweets.
4:46pm: The team has officially placed Walker and fellow hurlers Sam McWilliams and Stephen Tarpley on the IL, Thosar relays. New York also activated outfielder Cameron Maybin, whom it acquired from the Cubs on Tuesday.
4:06pm: The Mets will place right-hander Taijuan Walker on the 10-day injured list, Deesha Thosar of the New York Daily News was among those to report. Walker is dealing with tightness in his left side.
The Mets now have four notable starters on the IL, with Walker joining Jacob deGrom (right side tightness), Noah Syndergaard (Tommy John surgery recovery) and Carlos Carrasco (hamstring strain) on the shelf. Nevertheless, the Mets have gone 20-16 and are in possession of a one-game lead in the National League East.
For his part, Walker – whom the Mets signed to a two-year, $20MM guarantee in free agency – has more than held his own in 2021. The former Mariner, Diamondback and Blue Jay, 28, has pitched to a 2.05 ERA over eight starts and 44 innings. That’s obviously going to be difficult production to replace, but the Mets seem hopeful Walker won’t miss much time, per manager Luis Rojas (via Tim Healey of Newsday).
