CINCINNATI (AP) - Neil Walker hit two of Pittsburgh's six homers - its biggest power surge in six years - and the Pirates clinched home-field advantage for the NL's wild card playoff game by beat the Cincinnati Reds 8-3 Saturday.
Pittsburgh will host the Reds on Tuesday night in the Pirates' first playoff appearance in 21 years. They went 50-31 at PNC Park, the third-best home record in the NL.
Pittsburgh hit five homers off Bronson Arroyo (14-12), who had never given up that many in a game in his big league career. Walker homered twice off the right-hander, and Andrew McCutchen, Pedro Alvarez and Marlon Byrd also connected.
Prospect Andrew Lambo hit his first homer off Logan Ondrusek, the first time the Pirates had six since Aug. 22, 2007 at Colorado.
