MIAMI -- Nationals left fielder Jayson Werth exited Wednesday night's 3-1 win over the Marlins in the bottom of the fifth inning after experiencing tightness in his left hamstring.
The Nationals planned to give Werth the game off for Thursday's matinee, and manager Dusty Baker said he made the move as a precaution.
"I'm not really concerned about this," Baker said. "A younger player might have tried to push it and something [could] happen. But Jayson being a veteran, he knows his body pretty well."
Werth, who finished the game 1-for-2 and made a few sliding catches in the outfield, declined to elaborate to the media after the game but insisted "I'll be fine." Chris Heisey filled in as his replacement and went 0-for-2.

Werth became the second Nationals player to leave the game early after starter Joe Ross left after two scoreless innings with a blister on his right middle finger.
Baker has been careful with his veterans. Werth, who turns 37 next month, and Ryan Zimmerman are coming off injury-plagued 2015 seasons. Werth was limited to 88 games last season and never found a rhythm as he battled a plethora of injuries.
"I'm trying to get those guys past the point where you're not worried about them anymore," Baker said.
