MINNEAPOLIS – Joe Mauer and Justin Morneau hit back-to-back homers for the second straight night and Minnesota roughed up Seattle ace Felix Hernandez in a 9-6 victory over the Mariners on Saturday.

Mauer had two hits and three RBIs and Michael Cuddyer added a 427-foot, three-run homer off Sean White in the fifth inning. Joe Nathan picked up his fifth save in six chances.

Hernandez (4-2) gave up six runs – five earned – and six hits in four innings for the Mariners, who have lost six in a row.

After they both went deep in the fifth inning of an 11-0 win on Friday night, the Twins’ version of M&M Boys did it again against Hernandez in the third for an early 4-0 lead. Mauer is 10 for 16 (.625) with two homers and six RBIs against Hernandez in his career.

Francisco Liriano (2-4) was perfect through three innings. But he hit Ichiro Suzuki to start the fourth and appeared to deflate a little after that. He allowed five runs and six hits in five innings.

Mariners third baseman Adrian Beltre had three hits and two RBIs, including his first homer since Sept. 7, a span of 35 games and 151 plate appearances. Mike Sweeney added a two-run shot.

Seattle twice had Liriano on the ropes. Yuniesky Betancourt popped out with the bases loaded in the fourth. Beltre tried to steal third with one out in the fifth and was easily thrown out by the Gold Glover Mauer to snuff out a potential rally.

Just over a week ago, the Mariners were the surprise of baseball with a 31/2-game lead in the AL West. But they have lost 10 of their last 13 games, and fell behind early again on Saturday.

After giving up six runs and 10 hits in a loss to Texas on Monday, things got off to an ominous start for King Felix against the Twins. Leadoff hitter Denard Span hit a high pop fly that left fielder Wladimir Balentien lost in the baseball-colored roof. Span raced to second for a double and Matt Tolbert walked.

Hernandez then threw a wild pitch that allowed both runners to advance before Mauer doubled down the right-field line to make it 2-0.

Mauer is making up for lost time in a hurry. After missing the first 22 games with a back injury, Mauer made his season debut on May 1 and homered with his first swing. He is hitting .483 (14 for 29) with three doubles, three homers and nine RBIs in eight games.

Notes: The two-time Gold Glover Beltre made two errors, one a throwing miscue in the fourth that allowed Cuddyer to score. … Manager Don Wakamatsu and a team trainer visited the mound to check on Hernandez in the fourth inning, but he remained in the game. … Mauer received his Gold Glove and Silver Slugger awards for 2008 before the game.
