Three days after second baseman Jayson Nix fouled a pitch off his eye and needed surgery, outfielder Matt LaPorta was taken to a hospital with a mild concussion after being hit in the head with a pitch during a heated 9-1 victory over China at the Beijing Olympics that featured three ejections on Monday night - but little involvement from third baseman Matt Brown and relief pitcher Kevin Jepsen of the Salt Lake Bees.

"We're not here to fight with anyone else," outfielder Nate Schierholtz insisted.

It all started when LaPorta ran over Chinese catcher Wang Wei in a play at the plate in the fifth inning, forcing Wang from the game with a left knee injury while being called safe.

An inning later, Schierholtz took out replacement catcher Yang Yang while scoring to make it 5-0, and Yang had to be restrained from Schierholtz by his teammates while China manager Jim Lefebvre was ejected for arguing about the rough play. Yang later accounted for China's only run with a ninth-inning homer, and raised his right arm in the air while he ran the bases.

"The umpire should have ejected" Schierholtz, Lefebvre said. "That's when the game got out of hand."

Chinese reliever Chen Kun and pitching coach Steven Ontiveros were thrown out soon after when Chen drilled LaPorta in the back of the helmet to start the seventh. That came after Johnson and Ontiveros were called out for a discussion about the situation and warned by the umpiring crew.

Johnson, angrily pointing at Chen, and his staff rushed out to check on LaPorta, who was down for several minutes before getting up and leaving the game.

"We do not throw to hit people," Lefebvre said. "We do not teach that in China or in the U.S."

Brown had a sacrifice fly and a double for the Americans, but they did not need Jepsen. Starter Jake Arrieta struck out seven in six innings while allowing just two hits, before a trio of others each pitched an inning of relief. The Americans are 3-2 and still fighting to reach the medal round, while China fell to 1-4 in the tournament.
