Three-time Cy Young Award winner Max Scherzer left Wednesday's game against the Mets after the first inning due to injury.
The 36-year-old Scherzer later revealed a "tweaked" hamstring forced him from the ballgame, which the Mets won, 3-1. The Nats ace said the injury first acted up in his previous start, against the Toronto Blue Jays.
Scherzer suggested the injury isn't serious.
"I'm not really concerned about it," he said during a postgame video conference.
The right-hander said discomfort in the hamstring was forcing him to change his mechanics, so catcher Kurt Suzuki encourage him to head to the showers after the first frame.
Scherzer labored in his lone inning, throwing an uncharacteristic 27 pitches while appearing to struggle with both his velocity and control. The Mets plated one of their three runs in the frame, on a sacrifice fly by Dominic Smith.
The injury scare for Scherzer is the latest in a string of them involving key pitchers early in the shortened MLB season, even aside from the league's trouble containing coronavirus outbreaks affecting three teams.
Astros ace Justin Verlander was shut down a potentially season-ending forearm injury, while Clayton Kershaw was sidelined by a balky back, and budding Braves superstar Mike Soroka felled by a torn Achilles.
