Washington Nationals

Nationals pitcher Ross Detwiler made it through his bullpen session Saturday without any problems, and told reporters he will be able to make his next start Tuesday against the Orioles.

Detwiler was skipped in the rotation previously due to back spasms suffered in his last start. 

The Nationals recalled infielder Jeff Kobernus from Triple-A Syracuse following Friday's game against the Phillies.

Kobernus went 10 for 43 (.233) with four RBI in his last 10 games. He hit .333 with a home run and 20 RBI in the minors.

The Nationals have designated pitcher Yunesky Maya for assignment Friday.

Maya allowed two runs over 1/3 of an inning in his only major-league appearance May 21. He has a 5.80 ERA over 59 career innings in the majors.

Nationals closer Rafael Soriano earned his 14 save Friday night against the Phillies.

Soriano struck out one as he pitched a scoreless ninth. He has not allowed a run in his last two appearances after blowing back-to-back saves. He has lowered his ERA from 3.15 to 2.86 during that span.

Nationals pitcher Jordan Zimmermann had a solid performance to earn his eighth win of the season Friday night against the Phillies.

Zimmermann (8-2) allowed a run-scoring single in the second to Domonic Brown and a sacrifice fly in the fifth. The right-hander was charged with two runs and six hits over seven innings. He had a strike and no walks in a 5-2 win.

Zimmermann has allowed two runs or fewer in nine of his 10 starts. He is scheduled to make his next start Wednesday at Baltimore. He has allowed three runs in his last three starts (23 innings) away from home.
