Major League Baseball has suspended New York Yankees pitcher Michael Pineda 10 games for the use of pine tar against the Boston Red Sox on Wednesday.

Pineda was ejected in the second inning after umpires identified a large smear of tar on the pitcher's neck.

Pitchers are prohibited from using any foreign substance on their bodies to help aid with grip on the baseball.

In 2012, Tampa Bay Rays pitcher Joel Peralta was handed an eight-game suspension for the use of pine tar on his glove. In 2005, Brendan Donnelly, then of the Anaheim Angels, served a 10-game ban for the violation.

"We're scratching our head right now how that actually took place," Yankees GM Brian Cashman said after his team's loss at Fenway Park. "Clearly what took place in the second inning should not have taken place."

The 25-year-old Dominican was accused of using pine tar on his hand on April 10, another contest against the Red Sox, but denied all claims after the game.

This time he was much more admitting and apologetic.
