Oakland A’s right-hander Osvaldo Bido was placed on the 15-day injured list with right wrist flexor tendonitis, halting, for now, what has been a solid first season with the organization.

The move, one of a handful the A’s announced before they opened a three-game series against the Houston Astros at Minute Maid Park on Tuesday, is retroactive to Sept. 8. Manager Mark Kotsay said Bido could still return this month as the A’s finish the season, their last in Oakland, on Sept. 29.

Bido, in his first season with the A’s after signing with the team as a free agent last winter, owns a 5-3 record and a 3.41 ERA this year with 63 strikeouts over 63 1/3 innings. In his most recent start on Sept. 2 in Oakland against the Mariners, though, Bido allowed four earned runs in 5 1/3 innings.

Kotsay said Bido has been dealing with the injury, which affected his grips, “for a little while, and it got to the point where he just wasn’t capable of pushing through it. It’s a big loss for us. We obviously have enjoyed watching him have success.”

Bido was originally scheduled to make his 10th start of the season Tuesday as the A’s began a nine-game road trip. JP Sears instead pitched against the American League West-leading Astros as his start was moved up a day.

Joey Estes will now start today, and Mitch Spence is scheduled to start Thursday’s series finale.

Kotsay said left-hander Brady Basso will join the A’s rotation. Basso and first baseman Ryan Noda were recalled from Triple-A Las Vegas before Tuesday’s game.

Basso was recalled most recently last Thursday, throwing six scoreless innings in a start and no decision against Detroit on Saturday before being optioned on Sunday. He is 0-0 with a 1.93 ERA in four appearances overall with the A’s.

After the A’s finish the series in Houston, they’ll travel to Chicago, where they’ll stay for nearly a week. Oakland plays the White Sox from Friday to Sunday and the Cubs from Sept. 16-18.

Noda, a Volo, Illinois native, spent almost all of the 2023 season with the A’s, but after a poor start to 2024 when he hit just .128 with a .440 OPS, he was optioned to Triple-A on May 2.

With the Aviators, Noda batted .224 with 81 runs, 21 doubles, 22 home runs, 54 RBI, and 89 walks. He also owned a .391 on-base percentage and .877 OPS in 101 games in Triple-A.

Noda, 28, leads the Pacific Coast League in walks, ranks sixth in on-base percentage, seventh in runs scored, and is 10th in OPS. He had 50 starts at first base, 42 in right field, six in center field, and one as a DH with Las Vegas.

In another move Tuesday, the A’s optioned infielder Tristan Gray.

The A’s will evaluate Noda this month and then decide whether to re-sign him for next season.

“He still can hit the ball out of the ballpark. The power is there,” Kotsay said of Noda, who is out of options. “It’s a kind of time frame for him. He’s got 18 games to get a look at for his upcoming season, really.”

ANDUJAR UPDATE >> Outfielder Miguel Andujar underwent core muscle surgery Tuesday with Dr. William Meyers at the Vincera Institute in Philadelphia, the A’s said. Andujar will return to Oakland to begin rehab before the offseason. Andujar was placed on the 60-day IL last month.
