Hamilton started at second base and went 0-for-3 in Monday's 2-0 win over the Mariners.

A random start at second base for Hamilton isn't typically significant, but Monday's assignment came in the first game the Red Sox played without Rafael Devers. Kristian Campbell, Boston's primary second baseman, served as the designated hitter, which had been Devers' role all season. Hamilton is considered the superior fielder, and the Devers trade allows manager Alex Cora to keep Campbell's bat in the lineup without sacrificing a key defensive position. One game is not determinative, so it would be wise to monitor how Cora handles infielder roles going forward. Eventually, Alex Bregman (quadriceps) will return from the injured list, and Marcelo Mayer could also enter the second-base mix.

Lowe went 2-for-5 with a two-run home run in Monday's 7-1 win over the Orioles.

After launching his 14th home run of the season as part of a multi-hit game, Lowe has now hit safely in five straight games and has recorded multiple hits in four of those five contests. In that streak, he is 10-for-22 (.455 batting average) with one double, two walks and three RBI. The 30-year-old is slashing .260/.311/.457 in 258 at-bats.

Phillies manager Rob Thomson said Stott suffered a hyperextended elbow on a swing during Monday's 5-2 win over the Marlins, John Clark of NBC Sports Philadelphia reports.

Thomson added that Stott could sit out Tuesday's contest, but the Phillies' second baseman doesn't appear to be dealing with a long-term injury concern. Stott went 1-for-4 with a double in Monday's contest and is slashing .236/.300/.329 with four home runs, 27 RBI, 31 runs scored and 11 stolen bases across 271 plate appearances on the season.

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.
