Freddy Peralta took a no-hitter into the sixth inning and struck out 13 Rockies in the Brewers' 7-3 win over Colorado on Sunday.
The 13 strikeouts are the most in team history for a rookie.
Milwaukee held a 7-0 lead before putting away Colorado, taking three of the four games in the series this weekend in Denver.
Next up, the Brewers head to Arizona to take on the Diamondbacks. The three-game series begins Monday night.
