SEATTLE -- Chad Bettis dominated the Mariners with seven scoreless innings and rookie catcher Dustin Garneau cranked a three-run homer as the Rockies opened an Interleague series at Safeco Field with a 4-2 win on Friday night.
Bettis (7-5, 4.59 ERA) allowed just three hits with three walks and six strikeouts as Colorado won in its first game in Seattle since 2006. Reliever Christian Friedrich gave up a two-run homer to Kyle Seager in the eighth, but the Rockies held on for just their fourth win in 18 Interleague games.
"[Bettis is] fine. His last time out, he would never make an excuse for anything, but he was sick," said Rockies manager Walt Weiss. "He looked great tonight."
Mariners right-hander Hisashi Iwakuma (7-4, 4.05) had a three-hit shutout going with one out in the seventh, but then was knocked out by five straight hits, including Garneau's homer. The Mariners, who had won seven of their previous nine, fell to 68-74.
"To be honest, I made decent pitches," Iwakuma said of his seventh-inning struggles. "They put up good at-bats. The only bad pitch I had in that inning was the slider that kind of spun and backed up into his barrel. Besides that, I thought I did a pretty good job."
MOMENTS THAT MATTERED Garneau goes deep: It took Garneau 10 games to hit his first Major League homer, but he wasted very little time putting home run No. 2 in the books. After grounding out to third in the third and popping out to fellow catcher John Hicks in the fifth, Garneau broke the pitchers' duel wide open in the seventh, cranking a first-pitch slider from Iwakuma that Statcast™ estimated at 381 feet to left for a three-run shot.

Making the most of his opportunity:James Jones got his first start in center field for the Mariners since his September callup and came through with two hits, his first of the season after going 0-for-12 in earlier stints this year. Jones used his speed to leg out a double in the third inning on a grounder up the middle that eluded shortstop Daniel Descalso. When the ball rolled into shallow center, Jones just kept running and wound up at second, though he was stranded there. Jones led off the sixth with a single and advanced to third before again being left standing.
"He did a nice job in the leadoff spot today," said Seattle manager Lloyd McClendon. "He had a couple hits and ran the bases extremely well."
Safe and sound after six: Bettis' biggest trouble came in the sixth, when he allowed a leadoff single to Jones and walked Seager on four pitches to put runners on first and second with no outs. After working a full count to Nelson Cruz, Bettis got the Mariners slugger to ground into a 6-4-3 double play and later got Mark Trumbo to chase on a 1-2 changeup to get out of the inning unscathed.
"Double play was huge. We stress it so much, you get two outs with one pitch. You can minimize damage," Weiss said. "He's got the changeup he can go to to get that ground ball, he's got the two-seamer, so he's got some weapons, but that was a big one."
Seager keeps swinging it: The Mariners' third baseman continued his torrid recent run with a two-run homer in the eighth that cut the Rockies lead to 3-2. After Shawn O'Malley walked to lead off the inning against Friedrich, Seager jumped on the first pitch he saw for his 24th blast. Seager has hit .463 (25-for-54) with five homers and 18 RBIs over his last 14 games to hike his season average from .254 to .274.
"It was a pitch up in the zone a little and something I thought I could handle and fortunately it worked out," said Seager, who is one shy of his career-high homer total set last year. More >
"I don't think he hit a wall. He elevated some pitches. Obviously the one pitch that killed him was the backup slider. He'd been throwing extremely well and for some reason just left some pitches up that inning." -- McClendon, on Iwakuma
"Yeah, with me and Murph, I guess I am. I got three weeks on him, so I'm the veteran now." -- Garneau, on being the 'veteran' catcher after Tom Murphy was called up Friday
