Vogelsong (10-7, 2.85 ERA) has lost his last two starts in ugly fashion, allowing 11 runs in just 5.2 innings pitched, including against San Diego Sunday when he threw 35 pitches in a three-run first before getting yanked with no outs in the fourth.
Ben Sheets (4-3, 3.07) also looks to avoid his third consecutive loss after allowing 11 runs and five homers in 12 innings in his last two starts. Sheets gave up four hits Saturday against the Dodgers, but they all left the park in a 6-4 defeat.
First pitch is set for 7:15 p.m. PT with coverage on CSN Bay Area.
