MILWAUKEE -- Pedro Alvarez and Starling Marte hit solo home runs and Neil Walker had three hits including a pair of doubles as the Pittsburgh Pirates snapped a season-opening three-game losing streak with a 6-2 victory over the Milwaukee Brewers on Friday night at Miller Park.

First baseman Alvarez had two hits, including an RBI single, as did catcher Francisco Cervelli for the Pirates, who had dropped back-to-back games on walk-off hits at Cincinnati before coming to Milwaukee.

Left-hander Jeff Locke started 2015 on a high note, working six innings and holding Milwaukee to a pair of runs on seven hits and a walk with two strikeouts.

First baseman Adam Lind continued his hot start with the Brewers. He went 2-for-3 Friday and is now 12-for-13 on the season, with three walks and four RBIs.

Brewers right-hander Mike Fiers struck out eight in his first appearance of the season, but as was the case for the three starters before him this season, was done in by a bad inning and a glut of extra-base hits.

Fiers got off to a good start, retiring the Pirates in order in the first, but a leadoff double by second baseman Walker set the stage for another bad inning for Brewers pitching.

Walker advanced to third on a sacrifice by left fielder Marte, then scored on a base hit by Alvarez. A double by Cervelli put runners at second and third and shortstop Jody Mercer's sac fly to center gave Pittsburgh a 2-0 lead.

Fiers had a chance to get out of the inning with no further damage but gave up an RBI single to Locke before striking out third baseman Josh Harrison to end the inning.

Pittsburgh added runs in the fourth, on a leadoff home run by Alvarez, and the fifth on a sac fly by Marte.

Milwaukee scored a pair in the bottom of the fourth on a two-run single by Lind.

NOTES: Brewers RF Ryan Braun was back in the starting lineup after being limited to one pinch-hit appearance over the last two games because of a strained right side. ... After a three-game opening series that included roughly five hours of rain delays and an 11-inning game, Pirates manager Clint Hurdle said he planned to get his reserves some playing time this weekend. Among that group is OF Corey Hart, who spent the first nine years of his career with Milwaukee. Hart spent last season with Seattle and signed a one-year contract last December. He has seen just one pitch and gave Pittsburgh its only lead of the season with an RBI double. ... The Pirates entered Friday's game with a 15-54 record at Miller Park since the start of the 2007 season and 43-88 against the Brewers overall during that stretch. ... Friday was the start of 22 consecutive games against NL Central opponents for the Brewers.
