Miguel Montero hit a home run to begin the eighth inning and lift the Arizona Diamondbacks to a 2-1 victory over the Milwaukee Brewers on Tuesday night.

Montero reached down and drove a first-pitch slider from reliever Chris Capuano (1-2) to deep center for his fifth home run of the season.

Capuano fell to 0-2 in 12 relief appearances this season. His contract was selected on May 29 from Triple-A Nashville. Prior to this season, he had not pitched in the majors since Sept. 28, 2007 against San Diego. He had his second Tommy John surgery on May 15, 2008.

Blaine Boyer (3-2) pitched a scoreless seventh and eighth and Sam Demel earned his first career save as Arizona put a strong finishing touch on rookie starter Barry Enright' stellar outing.

Enright has been a bright spot for the Diamondbacks since he jumped from Double-A Mobile to the majors. He went five innings in his debut on June 30 after being recalled and beat the St. Louis Cardinals 4-2. He has not gone less than five innings nor allowed more than three runs in any of his eight starts.

He allowed one run on three hits over six innings and retired 13 of his last 16 batters. He struck out two and walked two.

The Diamondbacks have won five of the last six and two straight over the Brewers who had beaten them seven straight before Arizona snapped that streak with a 7-4 victory in 10 innings on Monday night.

Arizona chased Milwaukee starter Manny Parra in sixth after Mark Reynolds singled with one out and Stephen Drew walked. Todd Coffey came on and struck out pinch-hitter Ryan Church. Enright reached on an infield single, loading the bases, but Chris Young flied out to end the inning.

Parra hasn't won since July 3 and came in 0-4 with an 8.56 ERA in his last five starts. He allowed four hits, walked six and struck out six over 5 1-3 innings as he failed to get past the sixth inning in any of his 14 starts this season.

Alcides Escobar hit his third home run of the season, a solo shot, when he drove a 1-0 fastball just over the wall and the outstretched glove of left fielder Rusty Ryal in the second.

Parra cruised through the first three innings, but then loaded the bases with on two walks sandwiched around a double by Adam LaRoche with no outs in the fourth. He escaped that jam, but Arizona nicked him for a run in the fifth.

Young doubled to deep right-center field, stole third and scored on Justin Upton' sacrifice to short right-field. Right fielder Lorenzo Cain and second baseman Rickie Weeks tracked Upton's pop up down the first-base line. Weeks caught it with his back to the plate. He quickly turned and fired a one hopper to home, but Young easily beat throw.

Brewers outfielders Corey Hart (sore back) and Ryan Braun (left wrist strain) missed their second consecutive game. Both were hurt during Sunday's game against the Houston Astros. However, Hart did pinch hit in the eight and flied out.

Notes: Young hit his 20th home run Monday night, he became the majors' first player with 20 homers and 20 stolen bases this season. "It's a big turn around from last year for me," said Young, who hit .212 with 15 homers and 11 stolen bases in 134 games last season. He said that after being optioned to Triple-A Reno on Aug. 10, 2009 and being recalled 19 days later, he dedicated himself to improving in 2010. He had 22 stolen bases coming into Tuesday night's game. ... The Brewers televised Tuesday night's game commercial-free as part of the team's Community Foundation Week festivities. The club simultaneously ran an online auction of baseball experiences, including a clinic with pitching coach Rick Peterson and Trevor Hoffman. ... Chris Dickerson made his Milwaukee debut, starting in center field a day after being acquired from the Cincinnati Reds for Jim Edmonds.
