SEATTLE (AP) — Mike Moustakas hit a two-run home run and Omar Infante had a three-run double in a seven-run fourth inning and the Kansas City Royals beat the Seattle Mariners 8-2 on Wednesday night.

Alcides Escobar opened the fourth with a single to right off Roenis Elias (4-5), who had retired the first nine batters. Moustakas followed with his seventh homer over the right-field wall.

The Royals would score five more, all with two outs. Infante unloaded the bases with his double to left, then Jarrod Dyson and Escobar each followed with left-field RBI doubles.

Escobar had three hits - two in the fourth - and scored twice. Moustakas had three hits and two RBI.

Ryan Madson (1-1) worked 1-plus inning of hitless relief for the win.
