SAN FRANCISCO (AP) -- Tim Lincecum's turn in the rotation is being pushed up a day to Wednesday against Arizona, making the San Francisco Giants' ace available for a one-game playoff Monday with San Diego if the NL West title comes to that.

Giants manager Bruce Bochy also could decide to pitch the two-time reigning NL Cy Young Award winner on short rest Sunday in the season finale against the Padres if need be, though the hard-throwing righty hasn't gone on three days' rest in the majors.

Entering Tuesday night, the Giants lead the Padres by one game in the division race.

With Lincecum pitching Wednesday—still on normal rest—rookie Madison Bumgarner will now go in Thursday's series finale with the Diamondbacks.

Lincecum is 15-10 with a 3.51 ERA this season. After a career-worst five-start losing streak, he is 4-1 with a 2.08 ERA in his past five outings.
