CHICAGO — Aroldis Chapman is having an uneven first week with the Chicago Cubs.
Leonys Martin hit a go-ahead, two-run double off new Cubs closer in the eighth inning, lifting the Seattle Mariners over Chicago 4-1 Saturday.
Cubs manager Joe Maddon hoped Chapman would convert his second four-out save since being acquired from the Yankees.
"That part of the batting order just yells his name. That's the whole point," Maddon said. "To go through that moment and he's available and to not utilize him and then lose the game, I would have been really upset with myself."
Chapman's first week with the Cubs has included a save against the White Sox and an awkward interview about the domestic violence case that led to a 29-game suspension.
"It's not my favorite thing to do, but that's my job and it's the manager's decision," Chapman said through a translator of coming on in the eighth. "I'm ready to do anything."
Wade Miley (7-8) took a no-hit bid into the seventh inning before allowing Kris Bryant's single and Javier Baez's RBI groundout.
Jake Arrieta (12-5) walked Mike Zunino and Shawn O'Malley starting the eighth, pinch-hitter Luis Sardinas sacrificed against Hector Rondon, and Nori Aoki grounded to third, where Bryant threw out pinch-runner Guillermo Heredia at the plate, a call upheld in one of three home-plate video reviews.
Chapman allowed Martin's double to left-center on a 99.6 mph pitch, which put Seattle ahead 2-1.
"I tried to swing at a strike, a choke swing, and he threw me a strike," said Martin, who added he faced Chapman once before "a long time ago" in Cuba.
Martin stole third and scored on Chapman's wild pitch.
Seattle added a run in the ninth when shortstop Addison Russell threw high to first on Chris Iannetta's two-out grounder, allowing Franklin Gutierrez to score from third.
Edwin Diaz struck out pinch-hitter Anthony Rizzo and Dexter Fowler with two on to end the eighth. Steve Cishek worked around a hit in the ninth for his 25th save in 30 tries. Chicago had won its previous three games.
Miley allowed one hit over seven innings with a season-high nine strikeouts. He had lost his previous six starts since beating Cleveland on June 7.
"I tried not to think about it," Miley said of the potential no-hitter. "The guys in the dugout were getting farther and farther away from me, and I didn't like that at all."
Arrieta (12-5) allowed two runs, two hits and three walks in seven-plus innings with four strikeouts. He fell to 0-3 with a 4.88 ERA in five starts during July.
Fowler initially was called out by plate umpire Lance Barrett on Baez's grounder, but the call was overturned in a video review.
Chicago had a second run off Miley wiped out by replay when Bryant, trying to steal home on a pickoff throw to first, was thrown out at the plate in the seventh.
Mariners: RHP Nathan Karns (lower back strain) went on the 15-day disabled list, a day after he allowed five runs during a two-inning relief appearance. RHP Cody Martin was recalled from Triple-A Tacoma. ... RHP Taijuan Walker (foot) is scheduled to throw five innings Monday in a rehab start for Tacoma.
Mariners ace Felix Hernandez (5-4) is to start the series finale Sunday night against LHP Brian Matusz, who will be called up from Triple-A Iowa. That will give Kyle Hendricks and the rest of the rotation an extra day's rest. Maddon said RHP Justin Grimm will be optioned to Iowa.
