APRIL 17: Stammen’s surgery will be Sunday, tweets Dan Kolko of MASNsports.com. Stammen has been told that his ligaments look good, but the timetable for his return is still uncertain, per Kolko. James Wagner of the Washington Post tweets that Stammen believes he will miss the remainder of the season.
APRIL 16: 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. From 2012-14, Stammen averaged 81 innings per season, tallying a 2.93 ERA with 8.2 K/9 and 2.9 BB/9 as an important member of the Nationals’ relief corps. He joins a long list of injured Nationals that currently includes bullpen-mate Casey Janssen as well as Denard Span, Anthony Rendon and Nate McLouth. Rendon and Span, at least, are projected to return to the club later this month.
The Nationals have seen their bullpen depth take a hit since the end of last season. Tyler Clippard was traded to the A’s in exchange for Yunel Escobar, Rafael Soriano (who struggled late in the year but was a generally reliable closer for much of the year prior) was not re-signed, and Janssen has yet to debut due to shoulder troubles. Blake Treinen has been moved into a prominent bullpen role in the earlygoing, and the team has also received contributions from Aaron Barrett, Tanner Roark and rookie Rafael Martin (who whiffed five hitters in an impressive two-inning debut).
