Gelof (ribs) will begin a minor-league rehab assignment with Triple-A Las Vegas on Tuesday, Martin Gallegos of MLB.com reports.

Gelof has been out of commission since mid-March after suffering a fractured hamate bone in his right hand. Additionally, while on a minor-league rehab assignment in May, the infielder sustained a stress reaction in his ribs, which put him back on the shelf for over a month. Gelof posted a .211 average with 17 home runs, 49 RBI, 60 runs scored and 25 stolen bases over 138 games with the Athletics in 2024. Luis Urias has been productive at the plate (113 wRC+) while filling in at second base, but Gelof may push Urias to a utility role once activated.

Urias is not in the Athletics' starting lineup against the Astros on Monday.

Urias will begin Monday's game on the bench while Max Schuemann starts at the keystone and bats ninth. Urias has reached base safely in nine consecutive games, and over that span he has gone 8-for-31 (.258) with one steal, five runs scored, one home run and two RBI.

Campbell will serve as the designated hitter and bat ninth against the Mariners on Monday, Adam Jude of The Seattle Times reports.

The Red Sox will be experimenting with their lineup after trading Rafael Devers to the Giants on Sunday. Campbell will be the first to take on DH duties while David Hamilton starts at second base. Campbell has gone 8-for-37 (.216) with two doubles, one home run and five RBI since the beginning of June.

Garcia is out of the lineup for Monday's game against the Rockies.

The left-handed-hitting Garcia had started in each of the Nationals' last eight games -- including three matchups versus southpaws -- but he'll move to the bench for the series opener while lefty Carson Palmquist takes the bump for Colorado. With fresh call-up Brady House making his MLB debut Monday and likely to serve as the Nationals' everyday third baseman moving forward, the right-handed-hitting Amed Rosario could end up spelling Garcia more frequently at second base when the Nationals face lefties. Rosario had previously occupied the short side of a platoon at the hot corner with Jose Tena, who was optioned to Triple-A Rochester to open up a roster spot for House.

Sanoja is out of the lineup for Monday's game against the Phillies.

Sanoja will retreat to the bench after starting in four of the past five games and three different positions. The rookie doesn't have a direct path to a spot in the everyday lineup at the moment, but he should play regularly against left-handed pitching, and his ability to play all over the infield and outfield will allow him to make occasional starts versus righties, too.

Estrada went 2-for-5 with a run scored Sunday against Atlanta.

Estrada singled in his final two plate appearances of the game, giving him his third multi-hit effort in his last four starts. His Rockies debut was delayed until May 30 due to a wrist injury, but he's hit primarily second and cleanup across his 14 starts since. Estrada is hitting a solid .267 in 62 plate appearances, also tallying seven RBI and five runs scored.

Castro went 3-for-4 with a double during Sunday's 2-1 loss to Houston in 10 innings.

Castro extended his hit streak to eight games Sunday, delivering his fourth multi-hit performance during that stretch. The utility player has been on a tear lately, going 25-for-61 (.409) with five home runs, 12 runs scored and 10 RBI over his last 17 games. He owns a .290/.365/.483 slash line on the year.

Edman went 1-for-3 with a solo home run in Sunday's 5-4 win over the Giants.

Edman's 10th homer of the season came in the second inning, producing a 2-0 lead for the Dodgers. The 30-year-old was given two days off earlier in the week in addition to a team off day Thursday, so it's possible the Dodgers are trying to prevent an aggravation of an ankle injury that bothered him earlier in June. Edman still looks to be the starter at second base, though the team's complement of hitters is fully healthy and Hyeseong Kim has looked good in limited playing time. It's a competitive lineup, and Edman's .247/.283/.463 slash line may not be enough for him to be an everyday option. He's added 34 RBI, 30 runs scored, nine doubles, one triple and a stolen base over 53 games.

Cronenworth went 1-for-4 with a two-run home run in Sunday's 8-2 win over the Diamondbacks.

Cronenworth is enjoying a steady but unremarkable June -- he's hit safely in five straight games and in 10 of 14 contests for the month. However, his fourth-inning homer Sunday was his first extra-base hit since a May 28 double versus the Marlins, and he also picked up his first RBI since June 3 against the Giants. The infielder is now at a .241/.367/.400 slash line with five homers, 17 RBI, 21 runs scored and one stolen base across 46 games this season. Hitting consistently is half the battle, but Cronenworth's fantasy stock will remain fairly low if he can't get more involved in run production.

Fitzgerald is out of the lineup for Sunday's game against the Dodgers.

Christian Koss will step in at second base while Fitzgerald gets the night off for what will be his first game out of the lineup since May 28. While starting in each of the Giants' last 15 games, Fitzgerald hit just .184 with zero home runs, three stolen bases, two runs and two RBI.
