Strasburg, the Nationals' former No. 1 pick 2009, is 5-0 with a 2.36 ERA this season. The 27-year-old had Tommy John surgery on his pitching elbow in 2010, and the Nationals have been cautious with his workload since that procedure.

The Nationals shut down Strasburg at the end of the 2012 season with the Nationals heading to the playoffs. He had pitched 159.1 innings before the team opted to end his season.
