The Athletics reinstated Gelof (hand) from the 10-day injured list Saturday.

Gelof had a minimum stint on the IL while recovering from a right hand contusion and did not need to embark on a rehab assignment before returning to the majors. With Brian Serven also being called up, the Athletics optioned both Darell Hernaiz and Joey Meneses to Triple-A Las Vegas in corresponding moves. Prior to his injury, Gelof posted an .834 OPS with eight steals, 11 home runs and 29 RBI in 228 plate appearances.

Arias out of the lineup for Saturday's game against the White Sox, Tim Stebbins of MLB.com reports.

Arias will be on the bench to begin Saturday's contest while Daniel Schneemann starts at third base and bats seventh. Since coming off the 60-day injured list June 14, Arias is batting just .214 with one home run and two RBI, but he started the hot corner in each of the previous seven games and is expected to operate as the Guardians' preferred option at the position until Jose Ramirez (hand) returns from the injured list.

Atlanta reinstated Farmer (forearm) from the 10-day injured list Saturday.

Farmer has been on the 10-day IL since mid-May due to a strained right forearm. He was cleared for a rehab assignment in late June and went 2-for-20 with one home run, three RBI and five runs scored during his time in the minors. While he didn't look great at the plate during his rehab assignment, Farmer has progressed enough in his recovery to return to the majors, with his reinstatement from the IL corresponding with Atlanta placing Ha-Seong Kim (finger) on the 10-day IL.

Hayes (back) will stick with High-A Dayton this weekend and then have his rehab moved to Triple-A Louisville next week, MLB.com reports.

Hayes opened a rehab assignment with the Dragons on Friday, going 1-for-3 with a run scored while playing five innings at third base. He'll play an unspecified number of games for Louisville before rejoining the Reds. Given how close it is to the All-Star break, the organization may wait until after the Midsummer Classic to activate Hayes.

Karros went 3-for-4 with a triple, a walk, three runs scored and a stolen base in Friday's 15-3 win over the Giants.

Karros was a thorn in the Giants' side all game, scoring a game-high three runs from the eighth spot in the order. It continued a hot streak for the 23-year-old, who's hit safely in nine of his past 11 games with seven extra-base hits, six RBI, 10 runs scored and a stolen base during that span. On the season, he's slashing .263/.363/.420 with six homers, 26 RBI, 43 runs scored and three steals across 284 plate appearances.

Vargas went 2-for-3 with a three-run homer in Friday's 4-3 extra-inning loss to the Guardians.

Vargas supplied all of the White Sox's runs with a three-run homer in the fifth inning, which came before the nearly two-hour rain delay. The 26-year-old third baseman is now up to 20 home runs on the year, which is the first time he's reached that mark in a season since making his major-league debut with the Dodgers in 2022. Vargas is slashing .248/.359/.495 with 11 steals (in 13 attempts), 55 RBI and 58 runs scored across 374 plate appearances this season.

The Mariners selected Mastrobuoni's contract from Triple-A Tacoma on Friday.

Mastrobuoni was DFA'd by the Mariners in mid-June but is back with the big club to provide depth in the outfield after Julio Rodriguez (concussion) was placed on the 7-day injured list. Mastrobuoni has spent most of the 2026 season in Triple-A, where he has a .603 OPS with five steals, one home run and three RBI over 71 plate appearances.

Sanoja isn't in the lineup for Friday's game against the Athletics.

Sanoja will rest his legs Friday after going 9-for-16 with a homer, eight RBI and four runs scored during Miami's four-game series against the Rockies. His absence will allow Leo Jimenez to start at third base and bat ninth.

Muncy is not in the Athletics' starting lineup against the Marlins on Friday.

The Athletics will give the nod at third base to Joshua Kuroda-Grauer, who will bat fifth against Marlins right-hander Tyler Phillips in Friday's series opener. Muncy has reached base safely in each of his last eight games, going 8-for-28 (.286) with one steal, three walks, one home run and four RBI in that span.

Mead is absent from the lineup for Friday's contest against the Pirates.

Mead will begin this one on the bench after starting at third base in each of the Nationals' last four games. Jorbit Vivas will occupy the hot corner in Friday's series opener.
