CINCINNATI -- Marcus Semien and Jake Smolinski each hit a two-run homer in Oakland's four-run second inning, and the Athletics snapped their seven-game losing streak with a 6-1 victory over the Cincinnati Reds on Sunday.
Danny Valencia added a solo homer and Billy Butler had a season-high four hits - matching his combined total in eight previous June games - as Oakland also ended a nine-game road losing streak, the team's longest since an 11-game slide in 2005.
Kendall Graveman and four relievers combined to throttle the Reds' offense. Fernando Rodriguez (2-0) allowed one hit over two innings of relief for the win.
Ramon Cabrera doubled in Steve Selsky for Cincinnati's only run in the second inning. The Reds failed to complete a three-game sweep but still finished 5-4 on their homestand.
Neither starter pitched long enough to qualify for a win.
Reds left-hander John Lamb (1-4), who lasted a career-high 7 1/3 innings in his previous start Tuesday against St. Louis, tied his season low by finishing just four innings on Sunday, giving up seven hits and four runs with two walks and one strikeout.
Oakland manager Bob Melvin lifted Graveman after Joey Votto's single leading off the fifth. The right-hander also allowed seven hits, but only one run with two walks and five strikeouts in a season-low four-plus innings.
