Pinch hitter Xavier Nady homered off Huston Street to tie the game with one out in the ninth and Hunter Pence hit a go-ahead, two-run shot as the San Francisco Giants rallied to beat the San Diego Padres 7-5 Sunday.

The stunning rally got Tim Lincecum off the hook for the loss, but the righty still had his second straight shaky start for the NL West champion Giants.

Lincecum allowed a season-high three home runs, including a two-run shot by Logan Forsythe and solo homers by Chase Headley and Yasmani Grandal.

Lincecum might no longer be a lock for the No. 3 spot in the playoff rotation. Manager Bruce Bochy instead might consider lefty Barry Zito (14-8), who was left off the roster for all three postseason rounds during the team's improbable 2010 run to the World Series championship.
