"Nothing we haven't seen before," LaRoche said. The 23-year-old finished having allowed just one hit, and a Nationals offense, which had averaged 8.3 runs and 13.2 hits over its previous nine games, was left stuck in neutral. "He was going after us and just beat us," Desmond said. Unlike his last start, Stephen Strasburg said he wasn't affected by the heat tonight. It was 96 degrees at first pitch, but because it was a night game and shade covered the field, the conditions weren't all that tough. In addition, Strasburg said he made a point to drink a lot of fluids and also received an IV before the game as a precaution. Strasburg's nemesis today wasn't the heat, but Tyler Colvin. The left-handed-hitting first baseman hit two home runs off Strasburg, spoiling what was otherwise a very strong outing from the righty. "All I can really think of is two pitches," Strasburg said. "I don't think they were the right pitches to throw in that situation and I didn't have the right mindset." Strasburg was especially frustrated with the first home run he allowed to Colvin. It came on an 0-2 fastball which was practically right down the middle. "Dumb pitch," Strasburg said. "I spiked a changeup and he swung at it, and you've got a guy with some power up there, that's the last thing you want to do is try and throw an elevated fastball. I missed down in the zone a little bit and right into his swing plane. Just got to learn from it." And the second Colvin homer, the two-run shot in the fourth? "That was a changeup," Strasburg said. "With the free base open, I didn't want to walk him, and I just caught too much of the plate. The way the ball's been flying out here, he got it just well enough to get it over the wall."
