Bob Wickman celebrates saving the Tribe's 5-2 win.
Ben Broussard hit a two-run homer to give the Indians a 5-2 victory over Minnesota on Sunday.
That came after the Twins prevailed, 6-5, in 12 innings in the completion of Saturday's suspended game.
The Indians (80-82) made a 12-game improvement over last year.
"That's a great mark," Broussard said. "We made some strides."
Bob Wickman pitched a perfect ninth in the second game for his 13th save in 14 chances since returning from elbow surgery.
Michael Cuddyer's two-out double off David Riske (7-3) scored Jason Bartlett from first base in the bottom of the 12th to end Saturday's game more than 26 hours after it started.
The teams were tied, 5-5, when play was halted so the Metrodome field could be converted for a college football game between Penn State and Minnesota.
By winning in 20 minutes Sunday, the AL Central champion Twins temporarily kept their hopes alive of having home-field advantage in the division playoffs. By losing the regular game, however, Minnesota (92-70) will open the first round in New York against the AL East champion Yankees instead of the wild-card Boston Red Sox.
Kyle Lohse (9-13) both won and lost for Minnesota. He made 15 pitches and was the winner in the suspended game, then took the mound 20 minutes later to start. He allowed five hits and three runs over four innings, before leaving with a blistered finger.
Cliff Lee (14-8) pitched seven strong innings for his third straight win after going 1-7. The left-hander gave up two runs -- homers to Cuddyer and Matt LeCroy, five hits and struck out six.
"Cliff was outstanding again," manager Eric Wedge said. "It was real nice to see him finish strong."
Josh Phelps, Josh Bard and Ryan Ludwick hit consecutive two-out singles in the second inning for a 1-0 Cleveland lead.
Cuddyer's 12th homer tied it in the bottom half, but Broussard hit a two-run shot, his 17th, to make it 3-1 in the third.
LeCroy's ninth homer made it 3-2 in the fourth.
Grady Sizemore hit an RBI triple in the ninth and scored on Grant Balfour's wild pitch to make it 5-2.
Cliff Lee delivers a pitch during the Indians' 5-2 victory in Minnesota to close the 2004 season.
