Acuna went 3-for-4 with a home run, a double, two RBI and two additional runs in Tuesday's 10-1 win over the Nationals.

Though Jose Iglesias assumed leadoff duties for the second game in a row while the Mets' usual table setter, Francisco Lindor (back), was on the bench, Acuna stepped in at Lindor's usual spot at shortstop. The rookie made the most of his second career start, providing a spark at the bottom of the order and matching Iglesias' output with three hits. After an MRI revealed no structural damage to his back, Lindor said that he anticipates returning to the lineup later this week, so Acuna may not have many more chances to build on Tuesday's excellent performance.

Tovar went 3-for-5 with a solo home run, an additional RBI and an additional run scored in Tuesday's 8-2 win over the Diamondbacks.

Tovar supplied a solo shot in the third inning and an RBI single in the sixth. The shortstop has homered three times over his last five games, going 6-for-22 (.273) in that span. This is his first 25-homer campaign, and he's added a .266/.293/.469 slash line with 70 RBI, 80 runs scored and six stolen bases over 147 contests.

Abrams (shoulder) will start at shortstop and bat leadoff Tuesday against the Mets.

Left-shoulder soreness has prevented Abrams from playing in each of Washington's last four games, but he seems to finally be feeling better entering Tuesday's contest. The 23-year-old has been in a bit of a slump at the plate recently, slashing just .176/.194/.382 with two home runs and three RBI since the start of September.

Kiner-Falefa is not in the lineup for Tuesday's game in St. Louis.

Kiner-Falefa had been at shortstop and leading off for the Pirates' last six contests, but he will begin Tuesday's game on the bench. Nick Gonzales is getting a start at shortstop and will also be at the top of the batting order.

Cruz (ankle) remains out of the lineup for Tuesday's contest in St. Louis.

It's the second straight start Cruz has missed after he had to leave Sunday's tilt against the Royals with left ankle soreness. He is considered day-to-day. Michael Taylor will occupy center field as the Pirates try to even the series.

Lindor (back) is out of the lineup for Tuesday's game against the Nationals, Anthony DiComo of MLB.com reports.

The 30-year-old said Monday that he could return to the lineup within the next 2-to-5 days, so it's not a surprise he remains out of the starting nine for Tuesday's contest. Lindor should be back in action for the Mets later this week, assuming he can avoid a setback with the nagging back injury. Rookie Luisangel Acuna is starting at shortstop Tuesday for New York.

Fitzgerald (back) will start at shortstop and bat second in Tuesday's game versus the Orioles.

Fitzgerald missed the last three contests with lower-back tightness but is ready to go following an extra day off with the Giants idle Monday. He's sporting an .880 OPS over 84 games this season for San Francisco.

The Phillies reinstated Sosa (back) from the 10-day injured list Tuesday, Corey Seidman of NBC Sports Philadelphia reports.

The 28-year-old has been sidelined since Sept. 6 due to back spasms, and he'll rejoin the Phillies on Tuesday after a brief stay on the shelf. Alec Bohm (hand) also returned from the injured list over the weekend, so Sosa should reclaim his role as a utility infielder.

Vargas slashed .303/.406/.493 with four home runs and 11 steals in 38 Arizona Complex League games.

The 6-foot-4 infielder logged 30 starts at shortstop and four starts at third base, but many evaluators expect him to eventually outgrow the six and slide to the hot corner. Vargas' last official game of the year was July 11, yet he hit a home run in the ACL Dodgers' championship-clinching game over the ACL D-backs on July 30, per Kenny Van Doren of MiLB.com. Unlike ACL teammate Eduardo Quintero, Vargas did not get assigned to Single-A Rancho Cucamonga after the complex league wrapped up.

Tovar went 1-for-4 with a solo home run and two strikeouts in Monday's 3-2 win over the Diamondbacks.

Tovar showed of his power Monday when he took Merrill Kelly deep to the right-center field bullpen. It was Tovar's 24th homer of the season, which ties him with Michael Toglia for the team lead. Tovar entered August slashing .290/.314/.491 but has struggled mightily since to the tune of .194/.229/.388 with six homers and 16 RBI over his last 40 games.
