Stephen Strasburg thinks the Astros knew what was coming tonight. Even if they did, Houston still couldn’t do much to slow Strasburg down. In Strasburg’s six innings tonight, Astros hitters managed to score just two runs on six hits. The Nationals righty walked only one batter and struck out five, but when he came off the mound in the sixth inning, he told manager Davey Johnson he had a feeling he was tipping his pitches, specifically when Houston had runners in scoring position.
