Craig Stammen is back

Craig Stammen is back in the Majors and he will be asked to stop the Nats five game losing streak.

The Nationals recalled Stammen from Triple-A Syracuse and placed right-handed pitcher Tyler Walker on the 15-day disabled list, retroactive to June 20, with a right shoulder AC joint sprain.

Stammen, who will get the starting nod tonight at Atlanta, went 2-0 with a 2.25 ERA during a three-start International League stint with the Chiefs.

The 26 year-old Stammen began the season with the Nationals and went 1-2 with a 5.43 ERA in 12 starts before being optioned to Syracuse following his June 6 start vs. Cincinnati. Five of Stammen’s 12 assignments rendered quality starts, but the Nationals went just 1-4 in those contests.

Stammen is 5-9 with a 5.23 ERA in 31 career starts with Washington spanning two seasons (2009-present).

The 34-year-old Walker is 1-0 with one hold and a 3.57 ERA in 24 games for the Nationals.
