PHILADELPHIA (AP) — Washington Nationals general manager Mike Rizzo called Joe Girardi a “con artist” a day after Philadelphia’s manager asked umpires to check Max Scherzer for illegal substances during Tuesday night’s game.

“It’s embarrassing for Girardi, it’s embarrassing for the Phillies, it’s embarrassing for baseball,” Rizzo said in a radio interview Wednesday on Washington’s 106.7 The Fan.

Scherzer threw his glove and hat to the grass, then stared down Girardi after getting checked for a third time by umpires for sticky stuff in Washington’s 3-2 win.

Major league umpires began a crackdown on Monday by regularly examining pitchers for tacky substances that can give them a better grip on the baseball. Managers also can request a check, although umps can deny it if they believe it’s not in good faith.

Girardi said he became suspicious because Scherzer was touching his hair more than usual on the mound. Scherzer said he did that because he couldn’t grip the ball and needed moisture on his fingers. He also said he got tired of tasting resin.

“He’s a con artist,” Rizzo said of Girardi. “He’s been doing that for years on TV.”

Phillies President Dave Dombrowski defended his manager, who was ejected after he left the dugout when Scherzer stared him down.

“That’s not Joe Girardi,” he said. “It’s totally improper for (Rizzo) to say that. … Joe Girardi is the farthest from a con man of anybody that I know. He’s a very sincere individual. He was within his rights.”

Dombrowski added that he called Commissioner Rob Manfred’s office and MLB had already consulted with the umpires and determined Girardi’s request was legitimate.

“I love Joe Girardi,” Rizzo also said in his radio interview. “I’ve seen him play since he was in high school at Peoria, Illinois, scouted him at Northwestern. I know him well. But, I know him well.”
