BOSTON — Yankees pitcher Michael Pineda was ejected for using pine tar less than two weeks after appearing to get away with using a foreign substance in another game against Boston, and the Red Sox beat New York 5-1 on Wednesday night.

The right-hander was thrown out in the second inning when plate umpire Gerry Davis found the substance on the right side of Pineda’s neck after Red Sox manager John Farrell asked him to check. Pineda walked from the mound without protest.

Both Pineda and Davis said it was pine tar.

“When it’s that obvious, something has got to be said,” Farrell explained after the game. “Our awareness was heightened.”
