PEORIA, Ariz. (AP) Wil Myers hit a two-run homer and a three-run double in an eight-run fourth inning that powered the San Diego Padres to an 8-5 victory over the Cincinnati Reds on Monday night.

Myers, moving from the outfield to first base in his second season with San Diego, entered hitting .167 this spring. But he drove prospect Cody Reed's fastball to center field for his first home run, and his bases-loaded double off Layne Somsen ended the scoring in an inning that included pitcher James Shields' RBI single.

Shields struck out five through three hitless innings before running into trouble. Joey Votto ripped an 89 mph fastball for a two-run homer in the fourth. Shields walked two and hit a batter with a pitch in the fifth before leaving with one out.
