CLEVELAND (AP) -- The Indians didn't generate a lot of attention when they acquired Zach Walters at the trade deadline.
Walters made a headline of his own Wednesday with a one-out homer in the ninth inning to give Cleveland a 3-2 win over the Arizona Diamondbacks in the first game of a doubleheader.
Walters, acquired from Washington for Asdrubal Cabrera on July 31, hit a 1-2 pitch from Randall Delgado (1-3) that narrowly cleared the wall in right field.
Walters was sent to Triple-A Columbus following the trade. The left-handed hitter was called up Sunday when outfielder David Murphy and designated hitter Nick Swisher went on the disabled list with injuries. The home run was the fourth of his career.
"He's hit a couple balls right on the nose," Indians manager Terry Francona said. "On a day that it was probably going to take a home run to win it, it was good to see him do it. I'm sure that will help him relax."
Cody Allen (4-2) worked around a two-out walk in the ninth.
Trevor Bauer, pitching against the team that took him with the third pick of the 2011 draft, allowed two runs and struck out nine in a career-high eight innings.
Bauer didn't allow a hit until the sixth when Arizona scored to break a scoreless tie. Michael Brantley's two-run single put Cleveland ahead in the bottom of the inning, but the Diamondbacks tied the game in the seventh on Aaron Hill's RBI groundout.
Bauer faced the minimum 15 batters through five innings before running into problems in the sixth. Jake Lamb drew a leadoff walk before Xavier Paul lined a clean single to right, putting runners on first and third. Lamb scored when Jordan Pacheco hit into a double play.
Bauer clashed with both Arizona management and teammates, leading to a short tenure with the Diamondbacks. The right-hander was 1-2 with a 6.06 ERA in four starts for Arizona in 2012 and was traded to the Indians in December.
"That was two years ago," Bauer said. "I've long since moved on. They are just another team, nine more hitters I've got to try to get out. There is no bad blood between them and me."
Vidal Nuno retired the first eight hitters, striking out five, before Tyler Holt recorded his first major league hit, a two-out single in the third.
Tuesday night's game was postponed in the top of the fourth after a 3 hour, 40 minute rain delay, forcing the teams to play a doubleheader.
WHERE'S THE WEATHERMAN?
Francona wasn't particularly happy about Tuesday night's events that saw the game postponed in the fourth inning after the lengthy rain delay. The initial forecast said the rain would last about an hour and then clear out. "Whoever was doing the forecasting last night had a bad night," Francona said.
Francona said OF Michael Bourn (sore left hamstring) will DH in a minor league game Thursday and be activated Friday. Bourn had surgery on the hamstring in October, but the injury has bothered him all season. He hasn't played since July 5.
Diamondbacks: OF A.J. Pollock (broken right hand) is expected to resume his rehabilitation assignment at Triple-A Reno over the weekend. Pollock returned to Phoenix after being hit by a pitch on the same hand during his rehab debut in the Class A Arizona League, but tests showed no additional damage.
Indians: Swisher (sore right knee) will be examined by Dr. Neal S. ElAttrache, the team physician for the Dodgers, on Tuesday in Los Angeles. A determination on whether Swisher needs surgery could be made at that time.
Diamondbacks: After the doubleheader, Arizona continues its 10-game road trip with a four-game series in Miami on Thursday. Arizona RHP Chase Anderson (7-4) takes on RHP Brad Penny (1-0). Anderson is unbeaten in his past five starts, posting a 2-0 record with a 1.74 ERA over 31 innings.
Indians: Cleveland is off Thursday, but continues its five-game homestand Friday against Baltimore. Cleveland RHP Corey Kluber (13-6) faces LHP Wei-Yin Chen (12-4). Kluber is tied for the American League lead in wins and ranks third with a 2.46 ERA and 187 strikeouts.
