Strasburg threw only 16 pitches before leaving with hand issue in the first inning of Washington's 15-3 rout of the Baltimore Orioles on Friday night. Martinez said Strasburg was feeling numbness in his thumb and that the sensation originated in the wrist. The Nationals withstood the injury to Strasburg after rebounding from a defeat that took five days to decide and weathering a lengthy rain delay. His first outing came against the Orioles in a game that was suspended Sunday at Nationals Park and completed Friday at Camden Yards with Baltimore winning 6-2. Orioles: Asher Wojciechowski (0-1, 3.95) makes his sixth career appearance against the Nationals, still looking for his first win against them.
