The backbone of the Washington Nationals success since they became a perennial playoff contender has been starting pitching. Max Scherzer, Stephen Strasburg and Tanner Roark all have the potential to compete for a Cy Young Award, and the team appears content with Gio Gonzalez being the sole left-hander in the rotation.
Last season, Joe Ross held the final spot in the rotation. The 23-year old righty went 7-5 with a 3.43 ERA in 19 starts, but missed two months in the middle of the season due to shoulder inflammation.
