Vogelsong (3-2 2.50) has been outstanding in May, earning all three of his victories including a 1.56 ERA in five starts this month. He'll be facing off against joe Saunders (3-3 3.79) who earned his first win of the month in his last outing against the Dodgers, throwing 6.1 innings of four-run ball, though was aided greatly by some potent offense.
Speaking of potent offense, Arizona is batting a team-wide .330 (68-for-206) over their last six games, while the Giants are 11-7 during their 20 game stretch in 20 days, scoring at least three runs in their last eight games straight and 14 of their last 18.
First pitch is set for 7:15 p.m. PT with coverage on CSN Bay Area and KNBR 680 AM.
