Jake Arrieta struck out seven in six shutout innings while Teagarden and Nate Schierholtz each hit two-run doubles for the U.S.
China catcher Wang Wei was knocked out of the game with a left knee injury following a collision at the plate with Matt LaPorta in the fifth.
After Schierholtz made a hard slide home against backup catcher Yang Yang on a sacrifice fly in the sixth -- and Yang was held back from Schierholtz by teammates -- China manager Jim Lefebvre was ejected for arguing about the rough play.
Chinese reliever Chen Kun and China pitching coach Steven Ontiveros were tossed when Chen hit LaPorta in the head to start the seventh.
