LOS ANGELES (AP) — Yan Gomes homered in his Oakland debut, fellow newcomer Starling Marte got three hits and stole three bases, and the Athletics beat the Los Angeles Angels 8-3 on Sunday.

Gomes, acquired from Washington at the trade deadline Friday, hit a two-run homer. Marte joined the A’s a couple days earlier in a trade with Miami.

Daulton Jefferies (1-0) earned his first major league victory, allowing three runs and three hits in five innings. He walked three and struck out three as the playoff-contending A’s.

Drafted as the 37th overall pick in 2016, Jefferies had pitched just one previously in the majors, losing in a shaky start last year. Promoted from Triple-A Las Vegas for this outing, the 25-year-old righty did much better.

Reid Detmers (0-1) lost in his big league debut. The 22-year-old lefty was the 10th overall pick in the 2020 draft.

Detmers gave up six runs on six hits and two walks in 4 1/3 innings.

Matt Olson hit a three-run homer, his 28th, in the third and Gomes connected later in the inning for his 10th and a 5-3 lead.

Marte scored twice, drew a walk and increased his steal total to 26.

Max Stassi had a two-run homer for the Angels, who got just five hits. Shohei Ohtani went 0 for 4 and grounded into two double plays.

Angels manager Joe Maddon saw Detmers in the clubhouse before the game and shook his hand. He simply congratulated him and told him to have fun.

Detmers retired leadoff batter Mark Canha on a flyball and then walked Marte, who stole second and third. Detmers struck out Olson and Jed Lowrie to escape, but it took him 28 pitches to get through that frame.
