SCOTTSDALE, Ariz. -- Dae-Ho Lee, who has already locked up a spot as the Mariners' right-handed platoon first baseman, whacked a two-run double in the sixth inning and Nathan Karns fanned eight in six innings to pace an 8-5 victory over the Rockies in the Cactus League finale on Saturday afternoon at Salt River Fields at Talking Stick.
Lee's game-turning hit came during a four-run sixth against Rockies left-hander Chris Rusin, who missed much of the spring with left middle-finger inflammation and will begin the regular season in bullpen while working toward rotation-readiness. Rockies righty reliever Justin Miller gave up three runs on two hits and two walks without retiring a batter in the seventh.
Karns, the Mariners' fifth starter who will make his first start Saturday against the A's at Safeco Field, held the Rockies to three hits and three runs in six innings and finished the spring with a 5.42 ERA.
"It was definitely nice to get my work in my last start and feel good about where I'm at," said Karns. "I was trying to do too much at the beginning [of spring], but I've kind of found my rhythm and am settling into my own right now."
"Karns was really sharp. It was a nice way to wrap it up down here," said Mariners manager Scott Servais, whose club finished spring with a 16-14-3 record.
"We played a lot of games. We made it through. I think we're in a pretty good spot. Everybody is healthy, we got most of the bullpen guys an inning today, so we're ready to roll."
Rockies starter Jordan Lyles, announced earlier Saturday as the starter for Friday's home opener against the Padres, gave up one run in three innings of fleeting command. Lyles threw strikes on 15 of his 30 pitches. He escaped the first inning by working Robinson Cano into a double-play grounder, but paid for walking Kyle Seager with two out in the third when Cano doubled. Cano finished spring with a .368 batting average. Lyles finished spring with a 7.11 ERA.
"I didn't give up as many runs," Lyles said. "I walked three people, which is not ideal. Going into the season healthy, that's exciting. I'm just looking for a healthy season."
Rockies third baseman Nolan Arenado went 1-for-2 to end Cactus League play with a .542 batting average.
