Brewers extend mastery of Pirates in DH opener
Ryan Braun hit his 28th homer for the Brewers, who have won 19 of 22 to open a comfortable lead in the NL Central over second-place St. Louis.
Narveson (9-6) gave up five hits and struck out three before leaving in the sixth inning after having an issue with the nail on the middle finger of his left hand. The injury didn't appear to be related to the left thumb laceration that sent him to the 15-day disabled list this month.
Jeff Karstens (9-7) allowed two runs and six hits in seven innings, walking one and striking out five.
