Nationals ace Max Scherzer exited with an apparent injury after throwing just 12 pitches in Friday night's start against San Francisco.

There was no immediate report on Scherzer's condition. Washington typically doesn't announce information on player injuries until after a game ends.

Scherzer got Giants leadoff hitter LaMonte Wade Jr. to fly out for the first out of the game. Brandon Belt was up next and Nationals manager Dave Martinez and trainer Paul Lessard went out to the mound after Scherzer threw a 96 mph fastball that made the count 3-2.

Scherzer got down and squatted, then stretched from side to side before throwing one pitch in front of Martinez and Lessard. Scherzer left after that warmup throw.

The three-time Cy Young Award winner entered the game with a 5-4 record and a 2.22 ERA. Schezer began the night in second place in the NL with 104 strikeouts.
