Gold Glove first baseman Matt Olson will come off the injured list Tuesday for the A’s game against the Reds, The Chronicle has learned.

Olson, who hit 29 homers and drove in 84 runs last year, broke the hamate bone in his right hand March 21 in the team’s second game against the Mariners in Japan. He had surgery to remove the bone the following day.

He was 4-for-22 in a rehab assignment with Triple-A Las Vegas. He homered Friday and went 4-for-14 in his final three games.

With Olson’s return, the A’s are expected to designate first baseman Kendrys Morales for assignment. He was acquired from Toronto at the end of March to play first during Olson’s absence. With a three-man bench, the team can’t afford to keep a player who doesn’t have much versatility, especially with a full-time designated hitter in Khris Davis.

If Davis is unable to go Tuesday because of the hip injury he sustained running into the wall in left while making a terrific catch Sunday in Pittsburgh, there’s a chance Morales could stay another day or two if the team sends down outfielder Skye Bolt, but Morales isn’t likely to stick beyond that.

Morales hit .209 (19-for-91) with one homer and seven RBIs in 29 games. He did go 7-for-13 in the three-game series against the Pirates, and he is the A’s leader in hard-hit ball rate (50.0) and average exit velocity (92.5), so he’s likely to be picked up by another team if Oakland cannot work out a trade.

Briefly: Closer Blake Treinen, unavailable Saturday and Sunday with what he believed to be elbow tendinitis, is unlikely to require a stint on the injured list. ... Minor-leaguer starter James Kaprielian, acquired in the Sonny Gray deal with New York in 2017, threw three innings at extended spring training Monday and has one more outing before going on an assignment. ... Jharel Cotton, who — like Kaprielian — is coming back from Tommy John surgery, is likely to go on a rehab assignment soon. ... Minor-league starter A.J. Puk is throwing to hitters at extended spring training. ... Catcher Sean Murphy’s surgery for torn meniscus in his left knee has not yet been scheduled.
