PHOENIX -- Mike Napoli and Joey Butler smacked two-run homers in the sixth inning as the Indians traded rallies with the Brewers on Sunday, before Milwaukee's Yadiel Rivera finished matters with a walkoff homer to lead off the ninth and give the Brewers a 6-5 Cactus League victory at Maryvale Baseball Park.
Rivera's second homer of the spring was a shot to left field off Ryan Merritt on a 3-1 pitch.
Napoli's homer was his first for his new team. It came off Brewers bullpen candidate Junior Guerra, who pitched a scoreless fifth inning before running into trouble in the two-homer sixth.
