BUFFALO -- Asdrubal Cabrera could face fines, suspension or both after an altercation with home-plate umpire Jason Klein on Wednesday night at Dunn Tire Park.

After he was called out on strikes in the ninth inning of Triple-A Buffalo's 5-4 extra-inning loss to Rochester, Cabrera raised his bat over his head in the direction of Klein. Cabrera stepped toward the umpire as he continued to shout, while third baseman Andy Gonzalez tried to restrain him. It was to no avail, as Cabrera was ejected.

While walking off the field, Cabrera tossed his helmet and then threw his batting gloves behind his back without looking, hitting first-base umpire Justin Vogel.

"I don't know exactly what he was doing," Bisons manager Torey Lovullo said. "I was trying to just define what happened. I don't think there was any intention as to him trying to throw his equipment. He was trying to hit his helmet on the bat and [Klein] heard the sound. [Klein] actually didn't see the play, and that's what I was trying to talk to him about.

"We'll have to look at it. I'm sure there's replays and there's tapes, and if it gets to that point, I'm sure [International League president Randy Mobley] will get involved."

Cabrera was unavailable for comment afterward.

A defensive standout, Cabrera began the 2008 season as the Indians' starting second baseman, but he struggled mightily at the plate. The 22-year-old switch-hitter was batting .184 when the Indians demoted him to Buffalo on June 11.

The move seemed to be benefiting Cabrera, who held a .384 batting average going into Wednesday's game with the Red Wings.

Cabrera first was called up by the Indians in August 2007. Boasting a .283 average, he played in 45 games, which included starts in all 11 postseason games.
