The Giants will send out Ryan Vogelsong (10-6, 2.72 ERA), who currently sits fourth in the NL in ERA, but he led the league with a 2.27 mark prior to Monday's 14-2 loss in which he gave up eight runs and nine hits in 2.2 innings -- the first start of 2012 in which he'd failed to go at least six innings . Vogelsong has not in San Diego since 2005.
The Padres will counter with Clayton Richard (9-12, 3.91). He struggled mightily the last time he faced San Francisco, giving up seven runs in five innings of a 7-1 loss, and has lost all three of his outings versus the Giants this year.
First pitch is set for 1:05 p.m. PT with coverage on CSN Bay Area and KNBR 680 AM.
