TORONTO -- Jack Morris, a former World Series hero and a current Toronto Blue Jays broadcaster, said Thursday that he watched video after Wednesday night's game between the Jays and Red Sox and came away convinced Boston pitcher Clay Buchholz was throwing a spitball.

Morris said he didn't notice it during Wednesday's telecast.

"I found out because the guys on the video camera showed it to me right after the game," he said. "I didn't see it during the game. They showed it to me and said, 'What do you think of this?' and I said, 'Well, he's throwing a spitter. Cause that's what it is."

Morris's accusation was vigorously disputed by the Red Sox, including manager John Farrell and Buchholz, who said it's the first time he's been accused of throwing a spitball.

"Loading up with what, rosin?" Buchholz said. "I get wet from my hair. Are they talking about the stains on my shirt? There probably are stains on my shirt, because I've been wearing the same shirt for the last three years.

"I'm doing the same thing right now as I did in 2008, when I was sent down to Double-A. But I guess something's got to be wrong, right?'"

Video of Buchholz rubbing his pitching hand on his left forearm was shown on the Jays' pregame show Thursday night.

"He's got rosin on his arm," said Farrell, visibly annoyed. "He's not loading up; he's got rosin on his arm. As soon as someone pitches well or does well, they're cheating."
