"Cool weather, looking to get a grip, I can't say it's uncommon," he said. "Guys look to create a grip, but typically you're not looking to be as blatant [as Pineda]."
Asked whether he planned to watch more closely the next time Pineda pitches against Boston, Farrell said: "We'll see how the game unfolds."
Pineda did not allow a hit until rookie Xander Bogaerts lined a single to open the fifth inning. He allowed four hits in all, including a two-out double by David Ortiz in the sixth and a home run by Daniel Nava to open the seventh. He was lifted after the next batter, Bogaerts, grounded another single to left.
Ortiz said he was never aware that Pineda might have had something on his hand and that it was inconsequential if he did.
"Everybody uses pine tar in the league," Ortiz said. "It's not a big deal."
Veteran catcher David Ross, who did not play, said he was not aware of the situation, either.
"I'd rather know where the ball is going for me, personally," he said. "A lot of guys make sure they get a grip in cold weather. I don't think of it as cheating. Some guys might look at it that way. I don't."
Catcher A.J. Pierzynski, who struck out and lined out against Pineda, also expressed no interest in making an issue of what Pineda may have had on his hand.
"I didn't really think about it," he said. "I didn't see it. I don't know, he pitched good. That's it."
The bottom line for Yankees manager Joe Girardi?
"There is really not much for me to speak on concerning that," he said. "All I know is he pitched extremely well and we are glad to have him back."
