An MRI performed on the right elbow of right-hander Craig Stammen has revealed a torn flexor tendon that will require surgery to repair, the Nationals announced on Thursday. The unfortunate news could very well sideline Stammen for the remainder of the 2015 season, although manager Matt Williams has said the timeline will depend on the extent of the damage in the elbow (via CSN Washington’s Chase Hughes).
The 31-year-old Stammen has spent parts of the past seven seasons with the Nationals, and after struggling as a starter for the team in 2009-10 has emerged as a durable, reliable bullpen cog.
