“I like where I’m at now.”
Moore’s three-run homer off reliever Jordan Balazovic in the fifth inning gave Seattle a 7-3 lead.
Mariners rookie right-hander Bryce Miller (7-3) struck out seven while yielding six earned runs on eight hits in 5 2/3 innings.
Minnesota’s Matt Wallner hit his second home run of the day — a solo shot to left for his own first career multi-homer game — off Miller in a four-running sixth inning for the Twins.
Andrés Muñoz earned his second save after coaxing Max Kepler’s game-ending ground-out with a runner at second.
“Interesting game, interesting series,” said Mariners manager Scott Servais. “Obviously, the Twins are one of the hottest teams in baseball coming out of the (All-Star) break, so to get in here and win two out of three — you look at all three games, we could have won all three, we could’ve easily lost all three — and end up winning the series, you feel good about it.”
Twins starter Joe Ryan (9-7) lasted just 3 2/3 innings, yielding four earned runs on seven hits and striking out seven batters. He required 95 pitches to record 11 outs.
Recalled from Triple-A St. Paul on Wednesday, reliever Josh Winder gave a depleted Twins bullpen four innings of relief. He surrendered one earned run and struck out four batters.
“Somehow, we’re sitting there a swing away from winning the ballgame after all of that,” Minnesota manager Rocco Baldelli said. “That’s almost hard to believe, but we put ourselves in a good position. There was never any quit.”
Seattle acquired RHP reliever Trent Thornton from Toronto in exchange for minor league IF Mason McCoy. Thornton has appeared in four games this season for the Blue Jays, allowing one earned run in 5 1/3 innings pitched. Over parts of five seasons with Toronto, Thornton has appeared in 108 games, including 37 appearances in 2021 and 32 last year.
The Mariners said Thornton would be optioned to Triple-A Tacoma.
McCoy, 29, spent the past two seasons at Tacoma. He was hitting .234 with 11 homers this season.
Seattle also transferred LHP Marco Gonzales to the 60-day injured list to clear a 40-man spot for Thornton.
Mariners are off Thursday ahead of a three-game series at Arizona. RHP Logan Gilbert (8-5, 3.55 ERA) is scheduled to start Friday for Seattle. The Diamondbacks have yet to announce a starting pitcher.
