Nationals pitching prospect Stephen Strasburg struggled for the first time on Sunday, allowing four runs in less than five innings. Only three of Strasburg's runs were earned, but he lasted just 4 2/3 innings as Double-A Harrisburg battle Altoona. He gave up six hits and three walks while throwing 79 pitches (49 for strikes). It was reported on Saturday that Washington could promote Strasburg to Triple-A Syracuse soon.
