SEATTLE (AP) — George Kirby struck out a career-high 12 batters in seven scoreless innings, Ty France hit a two-run homer and the Seattle Mariners beat the Arizona Diamondbacks 3-1 on Saturday night.

Kirby (3-2) gave up two hits, recorded eight of his first nine outs via strikeout and retired his final 14 batters. He ran into his only bit of trouble in the third, giving up a one-out double to Blaze Alexander and a walk to Jake McCarthy before striking out Lourdes Gurriel Jr. and Ketel Marte.

Kirby hit 99.3 mph with his fastball and induced 23 swings and misses.

“Wow, George Kirby,” Mariners manager Scott Servais said. “Tough to get a hit tonight on both sides, but our guy was fantastic. Can’t say enough from where he came out in the first inning, probably as good a stuff as we’ve seen him have all year.”

Kirby extended his scoreless streak to 14 innings.
