MILWAUKEE -- Pedro Alvarez hit two home runs and Andrew McCutchen and Neil Walker also homered Saturday as the Pittsburgh Pirates beat the Milwaukee Brewers 5-2 at Miller Park.
Three of those home runs accounted for three of the Pirates' five hits off Brewers starter Mike Fiers (1-3), who lasted just four innings despite striking out five in his first start with Milwaukee since April 6.
McCutchen struck first, hitting a solo shot with two outs in the first inning. After Walker reached on a one-out hit in the second, Alvarez made it 3-0 with a home run down the right-field line. In the fourth, Walker put Pittsburgh ahead 4-0 with a one-out shot to center.
Alvarez hit his second homer of the game in the ninth, a solo shot off Alfredo Figaro.
Milwaukee's offense sputtered against left-hander Jeff Locke, stranding a runner at second in each of the first two innings. After putting two on with one out in the second, Locke retired 12 of his next 14 and ended the sixth with a double play by Jonathan Lucroy.
Locke (5-1) scattered three hits over his six scoreless innings, walked three and struck out a season-high seven to get his fifth win of the season. He lowered his ERA to 2.45, moving him into the top 10 in the National League.
Carlos Gomez put the Brewers on the board in the seventh, leading off the inning with a solo home run off reliever Justin Wilson. He added another homer with two outs in the ninth to cap off a 2-for-3 day with a walk.
NOTES: Brewers closer Jim Henderson was to be evaluated by team doctors Saturday after suffering a strained hamstring Friday in Milwaukee's 2-1 victory over Pittsburgh. Manager Ron Roenicke said "it might be awhile" before Henderson returns. If Henderson goes on the disabled list, Roenicke said he likely would use a "closer by committee" approach to the ninth inning. ... McCutchen has homered twice off Fiers this season. In 10 career at-bats against the Brewers' right-hander, McCutchen has four home runs. ... Milwaukee's bullpen had a 1.89 ERA over the previous 17 games and has held opponents to a .200 batting average during that stretch. ... Pittsburgh hasn't lost consecutive games since falling to Seattle and the Mets on May 8-9. The Pirates are 12-3 during that stretch. ... Gomez's two home runs marked the first multi-homer game of his career.
