The Indians waited through 4 hours and 23 minutes of rain Sunday to play the White Sox at U.S. Cellular Field. They waited so long that a day game turned into a night game.

It didn't matter.

They would have waited through enough rain to float an ark because they knew it could take them one step closer to where they're trying to go. That would be the postseason and the Indians took another step in that direction with a 7-1 victory over Chicago to complete a four-game sweep.

The victory the Indians' 12th straight against Chicago this season moved them to within a half-game of the AL wild card lead. Texas and Tampa Bay losers Sunday are tied for the two wild card spots at 81-67. The Indians who have won 10 of their last 14 games are a half-game behind them at 81-68.

The Indians have gone 15-2 against the White Sox this season. They have not beaten a team 15 times in one season since 1960 when they went 16-6 against the Washington Senators and 15-7 against the Kansas City Athletics.

It is the first time in franchise history that the Indians have swept three four-game series from a team in one season. It has not been done since the Brooklyn Dodgers according to Elias Sports Bureau did it to the 1963 New York Mets.

Zach McAllister (8-9 3.96) went 6 2/3 innings for the win. After going 0-2 in his last three starts McAllister allowed one run on six hits for the win. He struck out five and walked one on 96 pitches.

Manager Terry Francona rested regulars Michael Bourn and Jason Kipnis on Sunday. Matt Carson got a start in right field with Drew Stubbs moving to center and rookie Jose Ramirez replaced Kipnis at second.

"I've got a feeling about those guys" said Francona. "They're excited about playing."

Carson a Septemper call-up took advantage of his first start in the big leagues this year.

He gave the Indians a 1-0 lead off lefty Chris Sale with a two-out single in the second. Carson made it 2-0 in fifth with the first of four homers by the Tribe. He added an infield single in the sixth and a stolen base in the eighth.
