Hamels pitched with a lead for the first time since April 7 (his second start) but a wacky third inning saw him lose that advantage and the Phillies (26-29) never recovered.
Hamels was staked to a 3-0 lead, but the Brewers (20-33) scored two off the left-hander in the second inning and then used an error, two infield singles, a bloop single and a broken-bat single in the third to jump ahead 6-3 and eventually win their sixth game this month. Coming into Friday, Milwaukee was 5-22 in May.
Hamels lasted five innings and ended with this line: 12 H, 7 R, 6 ER, 0 BB, 3 K.
The lefty is now 1-9 this season and the Phillies are 1-11 in the games that he has started. Even more unbelievable, Hamels is the first Phillies pitcher since Kid Gleason in 1891 to lose nine games before the month of June. Gleason went 24-22 with a 3.51 ERA in 418 innings in 1891.
On a brighter note, the sizzling Brown hit his 14th and 15th homers of the season, catapulting him into the National League lead. His first of the night was a liner into the first row of right field, while the second was a deep shot to right field on a first-pitch fastball up in the zone. He finished May with 12 home runs and has six in his last five games.
The Phillies are back it on Saturday at 4:05 p.m. when Tyler Cloyd (1-1, 5.74) opposes Milwaukee's Wily Peralta (3-6, 6.35).
