Mauricio is out of the lineup for Sunday's game against the Mariners.

Mauricio will head to the bench for the series finale after he started in each of the Mets' last three contests while going 2-for-11 with a stolen base and a run. With Mauricio bowing out of the lineup, Mark Vientos will pick up a start at the hot corner.

The Nationals optioned Tena to Triple-A Rochester following Sunday's 11-9 loss to the Phillies.

Making a start at second base Sunday, Tena went 1-for-4 with an RBI double and his third stolen base of the season, but the performance wasn't enough for him to maintain his spot on the 26-man active roster heading into the Nationals' three-game series with the Mets, which begins Tuesday. The 24-year-old infielder has handled a limited role across his multiple stints in the big leagues this season, slashing .243/.341/.355 with no home runs, 16 RBI and 19 runs over 169 plate appearances.

The Mariners recalled Mastrobuoni from Triple-A Tacoma prior to Sunday's game against the Mets in Williamsport, Pa.

Seattle is designating Mastrobuoni as its 27th man for the 2025 MLB Little League Classic, so he'll most likely head back to Tacoma once the contest in Williamsport is completed. Mastrobuoni isn't in the lineup for Sunday's contest but is capable of serving as an in-game replacement at multiple infield or outfield positions.

Harris will start at third base and bat eighth in Sunday's game against the Angels.

After going 2-for-6 with two walks, two runs and an RBI in the first two contests of the series, Harris will remain in the lineup for a third straight game since being called up from Triple-A Las Vegas. So long as he continues to deliver productive at-bats, Harris will likely hold down the fort at third base until Max Muncy (hand) is cleared to return from the injured list.

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

Rengifo will retreat to the bench for the series finale after he had started in eight of the Angels' previous nine contests. Christian Moore will spell him at second base and will bat seventh.

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

After starting in each of the last five games, Moncada will get a breather as the Angels close out their series in Sacramento. Oswald Peraza will step in for Moncada at third base.

Karros is out of the lineup for Sunday's game against the Diamondbacks.

For the first time since he was called up from Triple-A Albuquerque on Aug. 8, Karros will receive a day off. The 23-year-old has kicked off his big-league career in impressive fashion, slashing .290/.389/.387 with three doubles, a 5:6 BB:K, three RBI and seven runs in nine games. Orlando Arcia will cover third base Sunday in his stead.

Brujan is out of the lineup for Sunday's game against the Guardians.

He made three starts over a five-game stretch prior to the return of Ronald Acuna from the IL, but Brujan has been stuck to the bench since. So long as Atlanta's regular outfield trio of Acuna, Michael Harris and Jurickson Profar remains healthy, Brujan will be in line for sporadic playing time.

Jung is out of the lineup for Sunday's game against the Blue Jays.

Jung will hit the bench after starting the Rangers' last nine games and going 5-for-34 (.147) with a 2:11 BB:K. The freshly recalled Cody Freeman will replace Jung at third base and bat eighth.

Bregman is out of the lineup for Sunday's game against the Marlins.

Bregman will check out of the starting nine for the first time since July 30 in what appears to be a routine day off. Abraham Toro will cover third base in Bregman's stead Sunday.
