New York Yankees' Michael Pineda was ejected in the second innings of the game against the Boston Red Sox after it was discovered he had a foreign substance on his neck.
The pitcher was approached by home plate umpire Gerry Davis after the request of Red Sox general manager John Farrell over suspicion of 'pine tar'.
Pineda could now face a suspension from the MLB, he was also spotted with a similar substance on his palm during the Yankees' last clash with the Red Sox on the 10th of April.
It is known throughout the league that occasionally pitchers use substances to help grip the ball on cold nights but managers don't often complain against the opposition due to the fact they don't want their own pitchers checked too.
Pineda's neck was covered in a brown smudge which was evidently pine tar and his use was so blatant in consecutive starts against Boston that Farrell felt compelled to request that the umpire would check Pineda for the foreign substance.
The pitcher was immediately ejected from the ball game after Davis ran his finger through the brown substance and confirmed the use of pine tar.
