Selik overpowered the Hillcats over six innings, allowing just four hits and striking out four with no walks. He allowed baserunners in five of his six innings, but induced two double plays and allowed just one runner to reach second base.
The Nats (44-49, 15-9) got the only run they needed in the first inning. After Soriano doubled to open the frame, Jeff Kobernus sacrificed him to third. Destin Hood then hit a sacrifice fly to center field that put Potomac in front 1-0.
