MINNEAPOLIS (AP) -- Justin Morneau hit a grand slam, Scott Baker pitched into the ninth inning, and the Minnesota Twins completed a three-game sweep of the Milwaukee Brewers with a 6-3 victory Sunday night.

Joe Mauer and Joe Crede also homered for Minnesota, which has scored 43 runs in its last four games. Baker (2-5) allowed seven hits and struck out six in 8 1-3 innings for his first win in three starts since May 8.

Mike Cameron hit a solo homer in the fourth, and Prince Fielder added a two-run shot in the ninth for the Brewers.

Leading 2-1 in the seventh, Morneau put Milwaukee away with a grand slam into the upper deck in right field. It was his fifth career slam.

Morneau's homer off Mitch Stetter came one pitch after Stetter hit Mauer in the right wrist with a pitch. Minnesota manager Ron Gardenhire had an animated discussion with plate umpire Adrian Johnson after the pitch.

Mauer, who improved his batting average to .438, homered in the first off Dave Bush (3-1).

Crede hit his third homer in four games in the fourth, but left with a bruised right hand in the seventh. The third baseman was hit in the hand by a pitch from Bush in the bottom of the sixth. He stayed in the game in the top of seventh, but left after an out was recorded. He walked off the field while opening and closing his hand in a fistlike motion and went straight to the team's clubhouse. He's listed as day-to-day.

Expected to be the ace of the young staff, Baker had allowed nine earned runs and 12 hits in his past two starts. He allowed at least five earned runs in four of his previous seven starts, and at least four earned runs in six of seven.

He kept the ball down in this one, and retired 11 in a row after allowing a home run to Cameron in the fourth inning.

With the homer, Cameron became the 20th player in major league history to have 250 home runs and 250 steals. He has 291 career steals.
