Jason Vargas allowed just one run in six solid innings to win his seventh game at home this season, and Casey Kotchman's two-run single in the sixth gave Seattle the lead for good in the Mariners' 3-2 win over the Kansas City Royals on Sunday.

Vargas (8-5) improved to 7-2 at Safeco Field this season, taking a shutout into the sixth inning. It was his second consecutive victory after going more than a month without a win.

Kansas City starter Kyle Davies (5-7) was Vargas' equal until the sixth inning when he gave up three straight one-out hits. The last single, a liner up the middle by Kotchman, scored Ichiro Suzuki and Chone Figgins with the go-ahead runs.
