Mets activate Taijuan Walker from IL, option fellow RHP Yennsy Diaz

The Mets have activated Taijuan Walker from the injured list, optioning Yennsy Diaz to Triple-A to free up the roster spot, per Tim Healey of Newsday. Walker missed the minimum amount of time with tightness in his side. Walked has excelled in eight starts this season with a 2.05 ERA/2.84 FIP across 44 innings.

Diaz has thrown two scoreless innings in two appearances. He came to the Mets this winter from the Blue Jays as part of the Steven Matz trade. While Diaz was mostly a starter with the Blue Jays, the Mets have thus far used him exclusively out of the pen both in the majors and in Triple-A.

The Mets also plan to get another arm back soon in Seth Lugo. The Mets plan to activate Lugo when he’s eligible to return on Monday, per Anthony DiComo of MLB.com. Lugo has been a huge piece of the Mets’ pitching staff over the past five seasons, but arm surgery has kept him from the mound so far this season. Over 167 games (38 starts) since 2016, Lugo has pitched to a 3.45 ERA/3.59 FIP in 383 1/3 innings, notching 25 wins, 32 holds and 12 saves.
