CINCINNATI (AP) -- Angel Pagan led off the game with a home run, Gregor Blanco and Pablo Sandoval connected later and Tim Lincecum came out of the bullpen to help the San Francisco Giants beat the Cincinnati Reds 8-3 on Wednesday, evening their NL division series at 2-all.

The Giants can complete an unprecedented comeback on Thursday. No team has recovered from a 2-0 deficit in a best-of-five series by winning three on the road.

Matt Cain, who lost the series opener and has yet to beat Cincinnati in three starts this season, will start Game 5 against Mat Latos.

The Reds haven't won a home playoff game in 17 years. One thing in Cincinnati's favor -- it hasn't dropped three straight at home all season.

Lincecum relieved in the fourth inning with the Giants ahead 3-2. The two-time NL Cy Young winner struck out six in 4 1-3 innings, allowing one run.
