SEATTLE (AP) - Michael Pineda allowed three hits over seven innings to help the Seattle Mariners break a six-game losing streak with a 5-2 victory over the Minnesota Twins on Monday night.

The Twins have lost nine straight for the first time since Sept. 9-19, 1998. They have not been 15 games below .500 since the end of the 2000 season when they were 69-93.

Pineda (5-2), the American League's Rookie of the Month for April, struck out seven and walked none as he lowered his ERA to 2.45. He went to a three-ball count on just two of the 26 batters he faced.

Pineda, who threw 70 strikes in his 99 pitches, entered the game with the highest percentage of strikes thrown (70.3) among AL pitchers and highest percentage of first-pitch strikes (73.7). He had 18 first-pitch strikes.

Adam Kennedy and Carlos Peguero hit consecutive home runs in the sixth inning. It was first time Seattle had back-to-back homers since Aug. 10, 2010, when Russell Branyan and Jose Lopez connected at Baltimore.

Kennedy had two hits and two RBIs, the second of which drove in Brandon Ryan from third in the eighth inning with a sacrifice fly.

Scott Baker (2-3) went six innings, allowing seven hits and four runs. He walked two and struck out eight.

Three Mariners errors sparked the only Twins rallies.

In the ninth, Jason Kubel reached on an error by first baseman Kennedy. With one out, Michael Cuddyer singled, sending Kubel to third. Delmon Young followed with a potential double-play grounder to third baseman Chone Figgins but his throw to second sailed into right field, scoring Kubel. Cuddyer then scored on Danny Valencia's groundout.

The Twins threatened in the sixth after a two-out error. Trevor Plouffe reached first when shortstop Luis Rodriguez's high throw brought Justin Smoak off the first-base bag. Kubel singled to center and Justin Morneau was hit by a pitch to load the bases.

Cuddyer then hit a hard grounder to second for a rally-ending forceout.

The Mariners jumped on Baker with a two-out run in the first. Figgins reached on a one-out infield single. Smoak struck out then Jack Cust bounced a double off the right-field wall to score Figgins.

They added a third-inning run in similar fashion. With Ichiro Suzuki on first with one out, Smoak lined a double into the right-field corner. Suzuki scored without a throw.
