Jason Vargas allowed one run and one hit in eight innings Thursday in a win over the Royals. If this was Vargas' last start with the Mariners, it was a nice one, as he improved to 11-7 with a 3.76 ERA. Billy Butler had both Royals hits on the night, supplying an RBI double off Vargas in the fourth and then doubling again off Tom Wilhelmsen in the ninth.
