Take the Padres out of Petco Park and match them against a southpaw starter and San Diego's offense comes alive. The Padres have scored the third-most runs versus lefties this season and rank in the top four in batting average against them at .281.

The Padres are playing at homer-friendly Great American Ball Park today - and facing lefty Brandon Finnegan. San Diego has scored 32 runs in his last four away matchups. The over has cashed in eight of San Diego's last nine games.

San Diego is pitching Drew Pomeranz, who is regressing after a hot start. He's 1-2 with a 6.19 ERA in his last three starts. Pomeranz allowed three homers in his last start - and that was pitching at Petco Park, the opposite of Great American Ball Park.

San Diego's bullpen is far from steady, while the Reds have the worst relief pitching in the National League.
