BOSTON (AP) -- Jon Lester says there was nothing but rosin -- which is perfectly legal -- on his glove when he beat the St. Louis Cardinals in Game 1 of the World Series.
A Cardinals minor leaguer posted a screen shot on Twitter showing a green substance on Lester's glove. Tyler Melling, a pitcher in the Florida State League, wrote: "Jon Lester using a little Vaseline inside the glove tonight?"
Lester, the Boston Red Sox left-hander, said before Game 2 on Thursday that "I can honestly tell you that all I use is rosin. So, it's obviously frustrating that after a night like last night, we should be having fun and running around with some energy today and I've got to stand here and answer questions about it."
Lester allowed five hits in 7 2-3 scoreless innings with eight strikeouts and a walk in the Red Sox's 8-1 victory.
Boston manager John Farrell also said Lester uses only rosin, which is provided on the pitcher's mound, to get a better grip.
"If you know Jon Lester, he sweats like a pig and he needs rosin," Farrell said.
Major League Baseball said in a statement on Thursday that "we cannot draw any conclusions from this video. There were no complaints from the Cardinals and the umpires never detected anything indicating a foreign substance throughout the game."
Section 8.02 of the Official Baseball Rules says a pitcher "shall not apply a foreign substance of any kind to the ball" and says the penalty for a violation is ejection and an automatic suspension.
Melling's tweet was later deleted.
"Obviously, when I get a text at 2 o'clock in the morning, it's not fun," a composed Lester said. "I understand. I saw the picture. It looks bad."
He also said he sweats a lot and rosin helps control that.
