Holliday is not in the lineup for Monday's game in Boston, Jake Rill of MLB.com reports.

After getting off to a fast start initially upon his promotion from Triple-A Norfolk on July 31, Holliday has stumbled to a .139/.208/.200 batting line with a 34.7 percent strikeout rate over his last 20 games. Livan Soto will start at second base and bat ninth for the Orioles on Monday.

Valdez is out of the lineup for Monday's game against the Orioles, Gabrielle Starr of the Boston Herald reports.

Valdez had started in three of the last four games but will take a seat against a left-hander. Romy Gonzalez draws the start at second base Monday. There had been speculation that Ceddanne Rafaela would move to the keystone with Trevor Story's return from the 60-day injured list Sunday, but that has not developed yet. It could, but early on with Story taking back over as the Red Sox's everyday shortstop, second base has been covered by Valdez against righties and Gonzalez against lefties.

India (elbow) is absent from the lineup for Monday's game in Atlanta.

India exited Sunday's win over the Mets due to left elbow discomfort. While the injury does not seem like a long-term concern, India will miss at least one start. Santiago Espinal will occupy second base for the Reds on Monday.

Gonzales went 2-for-4 with a run scored Sunday against the Nationals.

Gonzales was activated from the injured list Aug. 26 and has started 11 of 13 games since -- all of which have come at second base. He's hit .327 with six RBI and seven runs scored in that span while also striking out at only a 14 percent clip.

Iglesias went 1-for-4 with a stolen base in Sunday's loss to the Reds.

With Jeff McNeil (wrist) done for the season, the door is open for Iglesias to get an everyday role at second base down the stretch for the Mets. The 34-year-old infielder has been remarkably productive since joining the team in late May, and he's slowed down only a little in the second half, slashing .278/.326/.329 over 86 plate appearances since the beginning of August. Iglesias offers effectively no power and only a little speed, but consistent playing time will still give him some fantasy upside in deep formats.

Polanco went 1-for-4 with a two-run home run in a win over the Cardinals on Sunday.

Polanco got in on the fun of the Mariners' 13-hit barrage with a fifth-inning shot off Steven Matz with Justin Turner aboard, extending Seattle's lead to 9-2 at the time. Polanco snapped a nine-game homer drought with the round tripper, which was also just his second hit in the last eight contests. The 31-year-old notably went down on strikes in his other three plate appearances Sunday, pushing his strikeout rate to a career-worst 30.6 percent and highlighting one of the primary culprits behind his career-low .204 average, .296 OBP and .643 OPS.

The Mets acquired Alvarez from the Red Sox on Sunday in exchange for cash considerations.

The move replenishes some organizational utility depth for the Mets. Alvarez, 34, has spent all of the 2024 season at Triple-A Worcester, posting an .811 OPS with 18 home runs and 18 stolen bases while making starts at six different positions.

Horwitz went 2-for-2 with a two-run homer in Sunday's extra-innings loss to Atlanta.

Horwitz didn't get the start Sunday with lefty Chris Sale on the mound for the home side, but he pinch hit for Leo Jimenez in the eighth inning and launched a go-ahead homer off Joe Jimenez, only for Atlanta to tie it up in the bottom of the ninth and walk it off in the 11th. Horwitz was viewed as a hit-over-power prospect in the minors, but he's changing that perception in his first extended look at big-league pitching. The 26-year-old has gone yard three times in the last two games, and through 311 MLB plate appearances in 2024 he's slashing .274/.360/.467 with 12 homers and 34 RBI.

The Padres are mulling the possibility of moving Bogaerts back to shortstop as Ha-Seong Kim's (shoulder) progress stalls, AJ Cassavell of MLB.com reports.

Bogaerts has expressed a desire to remain at second base now that he's become comfortable there, but on Sunday he seemed to be amendable to a move back to shortstop if it meant getting Donovan Solano's bat in the lineup. The 31-year-old moved to shortstop mid-game Sunday versus the Giants after the Padres pinch-hit for shortstop Mason McCoy when they were trailing by five runs at the time. Bogaerts has now been used at shortstop four times this season but has not made a start there.

Bogaerts went 1-for-4 with a two-run homer in Sunday's loss to the Giants.

Bogaerts' only hit of the afternoon was a two-run shot to left in the eighth to bring the Padres within a run after they were down 6-0. That's his third home run over the last nine games after having just six in his other 86 games this season. He's showcased his lowest slugging percentage and OPS this year since his first full MLB season in 2014 and is now slashing .266/.210/.379 with 23 extra-base hits, 36 RBI, 46 runs, 10 steals and a 25:67 BB:K in 400 plate appearances.
