PHOENIX -- Try as he might, Patrick Corbin just can't seem to find his old form this season.
The Arizona Diamondbacks' left-hander was 20-13 combined in 2013 and 2015, missing the 2014 season to recover from major elbow surgery. This year hasn't gone so well for him.
Corbin (4-11) allowed four runs on eight hits in five-plus innings in the Diamondbacks' 15-6 loss to the Milwaukee Brewers in a four-hour marathon on Saturday night. He walked five, struck out five and dealt with at least two runners on base in every inning he worked.
Corbin hasn't won since June 21, going 0-5 in his last eight starts. However, he managed to find some positives in his latest outing.
"After that (first inning) I thought I made some good pitches," Corbin said. "They got a couple of hits but I was able to make pitches and work my way out of a couple of jams."
Corbin's stat line would've looked better if not for the Brewers' Ryan Braun, who homered twice and tied a team record by driving in seven runs.
Braun hit a pair of three-run homers and also had a sacrifice fly. He has 18 home runs this season and 25 career multihomer games.
Two of the runs charged to Corbin came from Braun's first home run. And while Corbin might have kept the Diamondbacks close, the bullpen could not. Arizona's pen gave up 11 runs in four innings.
"This is a big boy game. We do what we can do as coaches and manager and talk to them but it has to be inside of them," Diamondbacks manager Chip Hale said of his pitchers. "We have to do a better job of stemming the tide. Some of their hitters are swinging the bat really well now. We need to change the game plan up a little bit."
Brewers leadoff man Jonathan Villar reached base six times and scored three runs and Keon Broxton went 5 for 5 with two RBIs. Orlando Arcia scored four times in Milwaukee's highest-scoring game of the season.
Matt Garza (3-4) pitched a season-high 6 1/3 innings, giving up two earned runs and three hits.
"Just making pitches. Making them hit pitches that they weren't comfortable hitting and that's it," Garza said.
Milwaukee scored two runs on a hit, walk, wild pitch and two sacrifice flies in the first inning.
Reliever Evan Marshall gave up Braun's first home run and the second drive came against Dominic Leone. The Diamondbacks' bullpen then gave up six runs in the ninth.
Garza held Arizona scoreless on two hits until the seventh, when Welington Castillo hit a two-run homer.
Jhan Marinez came on with a runner at first and surrendered Jean Segura's two-run homer to make the score 9-4.

Brewers pitcher Chase Anderson acknowledged cheers from the crowd at Chase Field when he was welcomed back to Phoenix for the first time since being traded over the offseason. Anderson pitched six innings in a no-decision on Friday night.
Brewers catcher Martin Maldonado moved to second base in the fourth inning on what was ruled a defensive indifference in Friday night's game, but that was wiped out with a scoring change on Saturday. Maldonado was credited with his first stolen base of the season when it was determined that he was being held on at first base before the play.
Diamondbacks: OF A.J. Pollock, who sustained a fractured right elbow just before the season started, went 1 for 4 as the DH for the Arizona League Diamondbacks on Friday night. He's working toward a 2016 debut before the end of the month and will hit in another rookie league game Sunday. ... OF David Peralta is day-to-day with a wrist injury after being held out of Saturday's game.
Brewers: RHP Jimmy Nelson (6-10) gets the start on Sunday against Arizona. He is 1-1 with a 3.06 ERA in three career starts against the Diamondbacks.
Diamondbacks: RHP Archie Bradley takes on the Brewers. He got the win against Milwaukee on July 27, and is 4-7 with a 4.75 ERA this season.
