Major League Baseball announced Friday that it will not suspend Yankees pitcher Michael Pineda for having what appeared to be pine tar on his right hand during the first four innings of his start Thursday against the Red Sox."The umpires did not observe an application of a foreign substance during the game and the issue was not raised by the Red Sox," the league said in a statement. "Given those circumstances, there are no plans to issue a suspension, but we intend to talk to the Yankees regarding what occurred."Television images showed a substance on Pineda's throwing hand in the early innings, but his right hand was clean when he came out for the fifth inning of his eventual 4-1 victory."A foreign substance is illegal, but by the time we became aware of it, it was gone," Red Sox manager John Farrell said after the game.When Pineda came out for the fifth, Farrell said it appeared the hand had been cleaned, so he never went to the umpires.Pineda allowed four hits and struck out seven in six innings."I don't use pine tar," Pineda said when asked about the substance after the game. "It's dirt. I'm sweating on my hand too much in between innings."Yankees GM Brian Cashman said he heard from MLB on Friday but had no plans to talk to Pineda."I talked to (MLB vice president of baseball operations) Joe Torre , he gave me a holler. It's a resolved issue," said Cashman, who did not elaborate.
