Mets' left-handed pitcher Steven Matz is experiencing stiffness on the right side of his body, an "issue related to how he slept last night." The issue is not considered serious, and is, thankfully, unrelated to his pitching arm or the partial left lat tear that caused him to miss two months earlier this season.
Matz is currently scheduled to pitch tomorrow in Philadelphia, but it is possible that his start will be pushed back. Logan Verrett would start tomorrow if Matz is indeed unable to take the mound. There is also rain in the forecast for the rest of the week, which makes it even tougher to predict when each pitcher will start.
Matz is currently in the conversation to start the Mets' fourth postseason game, with Terry Collins recently talking up Bartolo Colon's chances to be a part of the team's playoff rotation. Whatever happens, Collins has "absolutely no plans" to use Matz in the bullpen. Over 35.2 innings this season, Matz has a 2.27 ERA with 34 strikeouts and 10 walks.
