Nunez will start at shortstop and bat ninth in Sunday's game against the Cubs.

Nunez will close the weekend with consecutive starts at shortstop after he went 1-for-3 in Saturday's 5-1 win. With the Nationals optioning CJ Abrams to Triple-A Rochester on Saturday, Nunez could take on an everyday role in the middle infield during the final week of the regular season.

The Padres placed McCoy on the 10-day injured list Sunday with back inflammation.

McCoy's IL stint is backdated to Thursday, making him eligible to return for the Padres' final game of the regular season Sept. 29. He has appeared in 19 games with the Padres this season, slashing .204/.278/.245. The Padres will replace McCoy on the 28-man active roster with veteran infielder Nick Ahmed, who was called up in a corresponding transaction.

The Padres selected Ahmed's contract on Sunday.

Ahmed is back in the majors and will provide infield depth in the absence of Mason McCoy, who was placed on the 10-day injured list with back inflammation. While Ahmed has been in the San Diego organization since Sept. 1, he never made an appearance with a minor-league affiliate and was instead working at the team's complex in Arizona. He had hit .232/.271/.300 in 69 games between the Dodgers and Giants this season.

Kiner-Falefa is not in the lineup for Sunday's game against the Reds.

Nick Gonzales will take over at shortstop and atop the batting order against right-hander Hunter Greene. Kiner-Falefa occupies those spots most days, and he's provided a .286 average this month as the Pirates' primary leadoff hitter, though it's been a rather empty batting average (five doubles, no homers, three RBI in his last 19 games).

Betts went 2-for-5 with a two-run homer and a stolen base in Saturday's loss to the Rockies.

Betts clubbed a two-out, two-run homer in his second at-bat to bring the Dodgers back within one run of Colorado and later added a leadoff single in the fifth, though he was left stranded after stealing second. It marked the All-Star's fourth long ball this month and his 18th on the campaign, while the steal was the second in his last three games. Betts is now slashing .274/.313/.534 in September with nine extra-base hits, 17 RBI, 12 runs and three stolen bases.

Acuna went 2-for-3 with a walk, a double and a solo home run in Saturday's 6-3 win over the Phillies.

The 22-year-old has been on fire since getting promoted last weekend, batting .385 (10-for-26) in his first eight big-league games with six extra-base hits, including three homers. Acuna's power display is especially impressive considering he hit only seven home runs in 131 games at Triple-A this season. Francisco Lindor (back) should return to the lineup any day now and reclaim the starting job at shortstop, but with a playoff spot on the line, the Mets could keep Acuna's red-hot bat in the lineup at another position.

Volpe went 1-for-4 with a two-run homer, a walk and a stolen base in Saturday's win over the Athletics.

Volpe slugged a leadoff homer in his first at-bat to increase New York's lead to three runs and drew a free pass his second time around before swiping his 27th bag of the campaign. The shortstop has now tallied two RBI in back-to-back contests while also hitting safely in three straight. The long ball was his 12th of the campaign and his first since Aug. 3 against the Blue Jays.

Moore went 0-for-3 with a walk, a hit-by-pitch, a stolen base and two runs in a win over the Rangers on Saturday.

Moore managed to still make an impact during a hitless effort, ringing up his 31st steal of the campaign and scoring on both occasions during which he reached safely. The 32-year-old has hit just .214 over 35 plate appearances in September, but he boasts a .343 on-base percentage in that same span thanks largely to a 14.3 percent walk rate.

Crawford went 2-for-4 with a triple and a run in a win over the Rangers on Saturday.

Crawford laced only his second three-bagger since the 2022 season as part of his third multi-hit effort during what is turning into a serviceable September. The veteran is hitting a modest .238 across 74 plate appearances this month, yet he boasts an impressive .351 on-base percentage thanks in part to his 12.2 percent walk rate in that same span. Crawford still has just a .205 batting average on the season, but that is an improved figure after his recent stretch of solid production.

Schuemann isn't in Oakland's lineup for Saturday's game against the Yankees.

Southpaw Carlos Rodon will toe the slab for New York on Saturday, meaning the left-handed bat of Schuemann won't be part of Oakland's starting nine. Nick Allen will replace him at the hot corner while batting ninth.
