MILWAUKEE -- Jimmy Nelson struck out a career-high nine batters and Jean Segura hit his first home run of the season as the Milwaukee Brewers earned their first victory of 2015 by knocking off the Pittsburgh Pirates, 6-0, at Miller Park.

Nelson on the opening day roster for the first time in his career, looked every bit the part of top prospect, pitching seven scoreless innings while holding the Pirates to infield singles in the first and sixth.

He also issued two walks and hit a batter, but was helped by two double plays and a runner caught stealing.

In their 0-4 start to the season, the Brewers struggled on the mound, on the field and at the plate but they were hitting on all cylinders in each of those categories Saturday.

Lind, the Brewers' best hitter through the first four games, got things started with a leadoff double in the second. He moved to third on a double by third baseman Aramis Ramirez and scored on a groundout by Khris Davis.

Pirates right-hander Vance Worley followed by hitting shortstop Jean Segura with a pitch, a move that would prove costly when second baseman Hector Gomez cleared the bases with a double to left.

Worley retired the next two batters to get out of the inning, and worked around a one-out walk in the third, but the Brewers added two in the fourth on a leadoff double by Davis and Segura's first home run of the season.

The offensive outburst provided a little breathing room for Nelson, who faced the minimum 12 batters through four innings and flashed his glove, too, snaring a come-backer by second baseman Neil Walker that started an inning-ending double play in the fourth.

Worley worked into the seventh, striking out four. He gave up six runs on seven hits and gave way to the bullpen after allowing a RBI double to center fielder Carlos Gomez.

NOTES: Pirates OF Corey Hart made his first start of the season. He took over in right field for Gregory Polanco, who was given a day off. ... Brewers manager Ron Roenicke altered his lineup slightly and moved 1B Adam Lind into the cleanup spot, with 3B Aramis Ramirez dropping to fifth. Lind has been off to a torrid start. He hit .615 with a home run, three doubles, four RBIs and four walks through the first four games. ... Milwaukee pitchers had given up 20 doubles through the first four games. ... Pittsburgh CF Andrew McCutchen was not in the lineup because of left knee soreness that forced him from the game Friday in the ninth inning. ... The Pirates wrap up their season-opening, six-game trip on Sunday. Milwaukee RHP Kyle Lohse (0-1, 21.60 ERA) will go up against Pittsburgh RHP Casey Sadler, who will be recalled from Triple-A. LHP Francisco Liriano was scheduled to start but was placed on baseball's paternity list Friday. He will make his season debut Wednesday against the Detroit Tigers.
