Don’t invite Cito Gaston and Roger Clemens to the same party.

Clemens yesterday was blasted by the Blue Jays manager, who still believes the Rocket played a role in his firing from the Blue Jays in 1997.

“He’s not one of my favorite people,” Gaston told reporters yesterday in Florida. “He’s a hell of a pitcher, but other than that, to me, he’s not a good person. A lot of people don’t like him. He’s a pretty good double-talker as far as I’m concerned.”

When asked if he believed Clemens got him fired after the Blue Jays finished fifth that year in the AL East, Gaston said, “I wouldn’t doubt that. He’s an [bleep-hole] himself, a complete [bleep-hole]. I’d say that loud, right in his face. It’s all about him. Nobody else but him. I wouldn’t doubt that at all.”

Clemens, who left Boston for Toronto in 1997, won two of his seven Cy Young Awards as a Blue Jay before joining the Yankees in 1999.

Gaston, who managed the Jays to back-to-back World Series titles in the early ’90s, also said Clemens was not a team player.

“When he’s on the mound, he’s 100 percent, but when he’s pitching everybody’s in the dugout pulling for him. When he’s not pitching, though, he’s not in the dugout,” Gaston said. “I just don’t think he’s supported his teammates as much as he wanted support. I know that there’s some guys who played on this team with Roger who don’t like him. It’s all about himself. It’s all Roger.”

Gaston denied knowledge of Clemens using performance-enhancing drugs, though Clemens is accused by author Jeff Pearlman in his book “The Rocket That Fell to Earth” of receiving injections of Winstrol while with the Jays when Gaston was manager.

“No, I never did,” Gaston said. “I didn’t know that about any of those guys if they were doing it when I was here or not.”

Clemens has yet to respond publicly to Gaston’s remarks.
