Olsen rocked, Nationals down big to Marlins

Scott Olsen’s position in the Nationals’ rotation, tenuous as it is, just became more uncertain. The left-hander gave up nine runs in 1 2/3 innings, and after Craig Stammen followed him by giving up a two-run single to Gaby Sanchez, the Nationals trail 14-3 in the third. Wes Helms and Donnie Murphy scored touchdowns for the Marlins - and that’s the last joke I’ll make about the football score tonight.

Olsen, who had lost five straight before tonight (including one outing where he lasted just 1 1/3 innings), isn’t in good shape when it comes to staying with the team after this year. If you assume Jordan Zimmermann, John Lannan, Livan Hernandez and Jason Marquis are all relative locks to be in the rotation, that leaves one spot for Olsen, Yunesky Maya, Ross Detwiler or whoever the Nationals might add in free agency or a trade. Olsen is arbitration-eligible, and with all the trouble he’s had, both with his injured left shoulder and his struggles since returning from the disabled list, it’s tough to see Washington bringing him back for another season.

Ian Desmond, Michael Morse and Nyjer Morgan have all driven in runs for the Nationals. Morgan, leading off the game, hasn’t been drilled in either of his at-bats in response to his collision with Brett Hayes at the plate last night.
