Mark Brouhard drove in five runs and Roy Howell and Charlie Moore had four hits apiece, helping the Milwaukee Brewers defeat the Oakland A's, 13-5, in Oakland yesterday and hand Mike Norris his first loss after six victories.

The 13 runs on 16 hits were high for Milwaukee this year and the most given up by A's pitchers, who had a 2.13 team ERA before the game.

Brouhard's first home run of the season in the second followed singles by Howell and Ted Simmons and a fielder's choice. Brouhard later hit a two-run single off Bo McLaughlin in the Brewers' five-run fifth.

Howell had three singles and also hit a two-run double in the third inning, which chased Norris, as he went four-for-four. Moore had three singles and a triple.

Pete Vuckovich evened his record at 2-2 with a six-inning effort. Jerry Augustine, who gave up a two-run pinch homer to Cliff Johnson in the seventh, pitched the final three innings to earn his first save of the year.

A crowd of 28,581 boosted Oakland's attendance to more than 500,000 for the season, 341,000 ahead of last year's pace.
