ANAHEIM — The A’s are ready to give another young starter an opportunity this weekend.

With Eric Surkamp’s start moved up to Friday from Saturday, left-hander Dillon Overton will get the start Saturday. Overton has won his past seven starts with Triple-A Nashville, with a 1.40 ERA in that span.

Manager Bob Melvin confirmed Overton’s Saturday debut after Thursday’s 5-4 win over the Angels.

“This is a guy we like, and he’s healthy now and pitching well,” Melvin said. “You want to get a guy here when he’s pitching well.”

Overton, 24, was the A’s second-round pick in 2013 from Oklahoma. His signing bonus went down when it was learned he needed Tommy John surgery. He spent the next year and a half rehabbing but remained on the team’s radar: Unlike Daniel Mengden, Overton was in big-league camp this spring.

Overton will be the fourth A’s starter to make his major-league debut this year, joining Mengden, Zach Neal and Sean Manaea. Andrew Triggs also made his first big-league start, but only for an emergency start; he had made several relief appearances before that and remains a reliever.

Briefly: Henderson Alvarez spent a second day visiting orthopedist Dr. James Andrews; Melvin said Alvarez is feeling better after coming out of a rehab start early last week, but no conclusions have been reached about why he twice has had to leave starts with shoulder discomfort. Andrews repaired Alvarez’s right shoulder in July. ... Outfielder Josh Reddick (thumb) went 1-for-4 for Triple-A Nashville against Iowa and is 1-for-11 in his rehab stint. He is expected to come off the DL on Monday. ... Home-plate umpire Paul Emmel left Thursday’s game in the bottom of the ninth after Jefry Marte’s bat slipped from his hands and hit Emmel in the head. Emmel needed stitches but is fine otherwise, according to the Angels.

Leading off

Blink and you missed him: Utilityman Arismendy Alcantara made his first start with Oakland on Thursday after stealing his first base with his new club one day earlier. “It was a blur,” manager Bob Melvin said. “He couldn’t wait to run. We actually had a hold on him, and as soon as we gave him the green light, he was gone.”
