MILWAUKEE - Claudio Vargas made sure the Brewers didn't rally again.
Vargas and three relievers combined on a four-hitter as Arizona sent Milwaukee to its first loss of the season.
"To take one here and whack them around a little bit feels pretty good," Arizona manager Bob Melvin said.
Milwaukee and Detroit, the last unbeaten teams in the major leagues, both were 5-0 before losing Sunday. The Brewers were trying to become the first major league team to open a season 6-0 all with come-from-behind wins, according to the Elias Sports Bureau.
Vargas pitched six innings, giving up only two singles and a walk while striking out six. He did not allow a runner past second base.
NOTABLE: For the first time this season, Milwaukee wore jerseys from the 1980s with its old ball-and-glove logo. The Brewers will wear the jerseys - similar to the type they wore when they started 13-0 in 1987 - during Sunday home games.
QUOTABLE: "You know you're not going to win 162 games, but it still hurts to lose this one because we wanted to be 6-0 going on the road." - Milwaukee manager Ned Yost.
