Mariners 4, Rangers 3
SEATTLE -- The Seattle Mariners hit three homers off new Texas Rangers starter Cole Hamels on the way to ending the Rangers' five-game winning streak with a 4-3 win on Friday night.
Left fielder Mark Trumbo, right fielder Nelson Cruz and second baseman Robinson Cano all hit solo homers, with Cruz and Cano going back-to-back in the sixth, as Seattle (51-59) won for the fourth time in five games.
The Rangers (54-54) failed to make up ground on a night when the American League West-leading Houston Astros lost again.
Hamels (0-1) fell to 0-3 with a 7.31 ERA in three starts against AL teams. He allowed four runs on eight hits over six innings, with Seattle's first run coming on a Hamels balk in the third inning.
Seattle starter Hisashi Iwakuma (3-2) threw a career-high 118 pitches over seven innings, allowing six hits and three walks.
Mariners closer Carson Smith, who has struggled in recent games, came on in the ninth and allowed just one hit on the way to his 11th save. Smith gave up a leadoff single to first baseman Mitch Moreland but retired the final three batters for his first save since Aug. 3.
Rangers second baseman Rougned Odor, Moreland and left fielder Josh Hamilton each had two hits in the loss. Catcher Bobby Wilson, in his third game since being claimed off the waiver wire from Tampa Bay, drove in a pair of runs with a second-inning double.
The Mariners have now won their past six games against the Rangers.
Wilson gave the Rangers a 2-0 lead with a two-out, two-run bloop double in the top of the second. Trumbo dove for the ball but couldn't make the catch, allowing runners to score from first and second base.
The Mariners got a run back on a third-inning balk, which brought first baseman Logan Morrison in from third base to cut the deficit to 2-1.
Morrison had doubled and moved to third on an infield single from shortstop Ketel Marte. Hamels then appeared to pick off Marte trying to steal second base. But home plate umpire Toby Basner called a balk on Hamels, allowing Morrison to score while putting Marte at second.
A wild pitch in the top of the fourth scored Moreland as the Rangers extended their lead to 3-1. That came after Trumbo misplayed another fly ball to put Moreland at third.
Trumbo made up for his defensive mishaps with a leadoff homer in the fifth, pulling Seattle within 3-2.
NOTES: The Rangers acquired 1B Mike Napoli from Boston before Friday's game. Napoli was acquired for cash considerations and the possibility of a player to be named later, but Napoli was not active for Friday's game. ... Friday marked the second start as a Ranger for LHP Cole Hamels, who was acquired from Philadelphia just before the trade deadline. ... Seattle SS Ketel Marte and LHP Rob Rasmussen were making their Mariners home debuts Friday night. Rasmussen was acquired in a deadline deal, while Marte was called up from Triple-A after Seattle made a series of deadline moves. ... While a pair of southpaw starters will be on the mound Saturday -- the Rangers' Martin Perez and Seattle's Mike Montgomery -- don't expect the left-handed power to drop off. Texas DH Prince Fielder (seven) and Mariners 3B Kyle Seager (six) are the two leading left-on-left home run hitters in the American League this season.
