Tension filled the air at Turner Field between the Nationals and Braves on Saturday night. Before anyone knew it, right-hander Stephen Strasburg and manager Davey Johnson were ejected from the game long before the Nationals defeated the Braves, 8-7, in 15 innings. The game was tied at 7 in the 15th, when Adam LaRoche led off the inning and hit a 1-2 pitch over the right-field wall for his 18th home run.
