Jake Arrieta got the win in his first appearance in the Olympics against a pretty bad Chinese team. He allowed 2 hits over 6 shutout innings. He struck out 7 and allowed 2 BBs.

Of note, Arrieta also hit 2 batters as the game turned into an ugly beanball fest. Several US players were hit, and Indians prospect Matt LaPorta leveled the Chinese catcher in a play at the plate. LaPorta was hit in the head with a pitch on his next at bat, and he had to leave the game.

China's only run came on a solo homer late in the game, and the Chinese hitter ran all the way around the bases with one fist in the air, and he stomped on home plate as he crossed.

This may be his only chance to pitch in the Olympics, although he is lined up to pitch in the gold medal game on Saturday if the USA team makes it that far.
