Seattle ? Mike Sweeney’s two-run double sparked a four-run first inning and the Seattle Mariners went on to an 8-4 victory over the Kansas City Royals on Saturday night.

Sweeney played 13 seasons for the Royals.

Jack Hannahan and Jack Wilson later had back-to-back two-out RBI doubles in the inning.

Hannahan also hit a home run. Rob Johnson contributed a two-run homer and Jose Lopez had a solo shot in the eighth, his 20th.

Ian Snell (3-1) worked five innings for the win. He stayed in the game long enough to earn the victory after he was hit on the right forearm by Mitch Maier’s line drive in the fifth.

The Royals’ John Buck hit a two-run home run on an 0-2 pitch from Snell in the third. In the ninth, Mark Teahan and Maier both homered. It was the rookie Maier’s third career home run in five games.

Gil Meche (6-10), who threw 39 pitches in the first inning, took the loss. It’s the third time Meche has allowed seven or more runs this season.
