The Athletics recalled Gelof from Triple-A Las Vegas on Monday.

Infielder Luis Urias was designated for assignment in a corresponding move, clearing the way for Gelof to rejoin the Athletics for the first time in the second half. Gelof spent the first part of the season on the injured list while recovering from a procedure on his right wrist from March, then was set back after sustaining a rib injury while on a rehab assignment in May. Upon being activated in early July, Gelof went just 2-for-25 with 13 strikeouts in eight games before being demoted to Triple-A, where he's produced a .259/.342/.556 slash line with 11 home runs and nine stolen bases in 33 games. Gelof could get some starts at second base as he rejoins the big club, though Darell Hernaiz is likely viewed as the Athletics' primary option at that position.

Hamilton will start at second base and bat eighth in Monday's game against the Orioles, Gabrielle Starr of the Boston Herald reports.

Hamilton is slashing just .193/.252/.293 over 153 plate appearances on the season for Boston, but in spite of that lack of production, he seems to have temporarily captured a regular spot in the starting nine at the keystone when the Red Sox face right-handed pitching. With Wilyer Abreu's (calf) recent move to the injured list allowing Ceddanne Rafaela to shift back to the outfield, Hamilton started in the Red Sox's previous two matchups versus righties and went 4-for-8 with a triple, two walks, four runs and one stolen base between those contests. Hamilton's track record in the majors suggests he shouldn't be expected to offer much impact with the bat moving forward, but he could be a decent source of steals while he's playing at least somewhat regularly.

Keaschall is not in the lineup for Monday's contest in Toronto.

Keaschall had started every game since coming off the injured list Aug. 5, so he's earned a breather for the series opener versus the Blue Jays. Kody Clemens will replace Keaschall at second base Monday.

The Guardians recalled Wilson from Triple-A Columbus on Monday.

Wilson has just a .472 OPS and 40 percent strikeout rate in 32 games with the big club this season. He'll likely be in the majors for only a few days while Daniel Schneemann is on paternity leave.

The Guardians placed Schneemann on the paternity list Monday.

Schneemann will likely miss all three games of his team's three-game set against the Rays that begins Monday as he welcomes a new addition to the family. Will Wilson was recalled from Triple-A Columbus to take Schneemann's spot on the active roster.

The Royals reinstated Massey (wrist/ankle/back) from the 10-day injured list Monday.

Massey will make his return to the Royals for the first time since early June, after he was initially deactivated due to a left ankle sprain before being pulled off two separate rehab assignments on account of a fractured right wrist and a tight back. He began a third rehab assignment Aug. 9 and emerged from his two-week stint in the minors unscathed while slashing .245/.310/.415 with a pair of home runs in 12 games for Triple-A Omaha. With Kansas City optioning John Rave to Triple-A in a corresponding move, the left-handed-hitting Massey could be in line for a regular spot in the lineup versus righties, though he may eventually move to the bench on a more frequent basis once the Royals reinstate Jac Caglianone (hamstring) from the IL.

Massey (wrist/ankle/back) has slashed .245/.310/.415 with two home runs, three doubles and a 4:14 BB:K in 12 games since beginning a rehab assignment with Triple-A Omaha on Aug. 9.

Initially placed on the 10-day injured list June 10 due to a left ankle sprain, Massey then sustained a hairline fracture to his right wrist while rehabbing with Omaha in late June. He started up a new rehab assignment after the All-Star break, only to be shut down again when he developed back tightness. Now in the midst of his third rehab assignment, Massey is looking healthy and turned in a productive weekend with Omaha, going 4-for-14 with a pair of home runs and a double from Friday through Sunday. He's been rotating between second base and left field during his time in the minors and could contend for playing time at either position with the Royals once he's activated from the IL.

Chisholm went 2-for-4 with a pair of two-run home runs in Sunday's 7-2 win over the Red Sox.

Chisholm opened the scoring in the second inning with a blast off Dustin May, and he provided the last runs of the game in the eighth, when he took Walker Buehler deep. Power has been on the rise for Chisholm lately, as he has now homered five times over his last 12 games, though he's batting a modest .256 (10-for-39) in that span. On the year, the infielder is at a .239/.333/.484 slash line through 98 contests. He's matched his career-high total in homers (24) in 49 fewer games than last year while adding 62 RBI, 59 runs scored and 22 stolen bases in 2025.

Semien said after Sunday's 5-0 win over the Guardians that he has been diagnosed with a fractured third metatarsal and a Lisfranc sprain in his left foot, which will likely require 4-to-6 weeks of recovery, Shawn McFarland of The Dallas Morning News reports.

Texas placed Semien on the 10-day injured list Saturday with what the team listed as a left foot contusion, but follow-up tests on the foot evidently revealed that he was dealing with structural damage. With five weeks left in the regular season, the 34-year-old now appears at risk of being shut down for 2025, unless the Rangers are able to clinch a playoff spot and make a deep run in October. Ezequiel Duran drew the start at second base Sunday, and he could handle the bulk of the work at that position while Semien is on the shelf.

Young is out of the lineup for Sunday's game against the Athletics.

The left-handed-hitting Young had started in each of Seattle's last three games, but he'll head to the bench Sunday while the Athletics send southpaw Jacob Lopez to the hill. Jorge Polanco will replace Young at second base and will bat seventh.
