Max Scherzer used the PitchCom system for transmitting signs for the first time Wednesday night in his Subway Series debut against the Yankees, saying catcher Tomas Nido wanted him to try it.

He may use it again after pitching seven shutout innings against the Yankees, but he made one thing crystal clear: he doesn’t think PitchCom belongs in the game.

“It works. Does it help? Yes. But I also think it should be illegal,” Scherzer said after the Mets’ walk-off win over the Yankees. “I don’t think it should be in the game.”
