Atlanta outrighted Keirsey to Triple-A Gwinnett on Thursday, Harrison Smajovits of SI.com reports.

Keirsey has lost his spot on Atlanta's 40-man roster heading into the winter. The speedy Keirsey will remain in the organization as outfield depth. He's managed a lowly .357 OPS in 107 plate appearances at the big-league level.

After playing with some discomfort down the stretch of the regular season, Marsee had his elbow examined before opting for surgery.

Marsee put together a .231/.348/.359 batting line with 11 home runs and 23 stolen bases this season for the Marlins.

Marsee will undergo a UCL repair with an internal brace on his left elbow Monday, Christina De Nicola of MLB.com reports.

Marsee played through elbow soreness down the stretch of the regular season, and surgery was recommended following a visit with Dr. Keith Meister. He is expected to be ready to play in games again in six months, which puts his availability for Opening Day in doubt. Marsee slashed .231/.348/.359 with 11 home runs and 23 stolen bases this season for Miami.

Acuna underwent an MRI on his right knee after Tuesday's NLDS Game 3 loss to the Dodgers, which came back negative, Jesus Cano of The Athletic reports.

Acuna experienced lingering soreness in the knee after tweaking it on a stolen base in Sunday's Game 2 win for Atlanta. He was deployed at designated hitter in Game 3, but Acuna is back in right field for Game 4 after imaging returned clean. Drake Baldwin will slot in at DH on Wednesday, while Sean Murphy will do the catching.

Lara isn't in the lineup for Game 3 of the NLDS against the Padres on Tuesday.

Lara will step out of the starting nine Tuesday to allow the lefty-hitting Sal Frelick start in right field against right-handed starter Nick Pivetta.

Acuna is starting at designated hitter rather than right field in Tuesday's ALDS Game 3 versus the Dodgers due to a sore right knee, Mark Bowman of MLB.com reports.

Acuna remains sore after banging up his knee on a slide Sunday in Game 3, so Atlanta will ease the stress on him a bit by inserting him into the DH slot. Lane Thomas will patrol right field for Atlanta. Acuna is 2-for-9 with two runs scored and a stolen base in the first two games of the series.

Yastrzemski is absent from the lineup Tuesday for Game 3 of the NLDS against the Dodgers.

The left-handed-hitting Yastrzemski didn't start the first two games of the series versus lefty hurlers, and he will remain out of the lineup for Game 3 even though righty Yoshinobu Yamamoto is toeing the rubber. Mauricio Dubon will play left field, Ha-Seong Kim will handle shortstop and Sean Murphy is serving as Atlanta's designated hitter.

Harris went 3-for-5 with a double, a triple, one RBI and one run in Game 2 of the NLDS against the Dodgers on Sunday.

The center fielder was the only Atlanta player with any extra-base hits while also providing half of his club's total knocks. Harris came to the plate in the top of the ninth inning a homer short of a cycle, but he instead grounded out to second. It's been an electric start to the playoffs for the 25-year-old, who has gone 8-for-20 with three-extra base hits, four RBI and four runs through five games.

Chourio went 1-for-4 with two RBI in Game 2 of the NLDS against the Padres on Sunday.

The 22-year-old outfielder came through in the clutch during the bottom of the ninth inning with a two-out, two-run single off All-Star closer Mason Miller to turn a 3-2 deficit into a 4-3 victory. Chourio clubbed a two-run homer in Game 1 on Saturday and has been the key offensive cog for the Brewers in the first two games of the series, driving in four of the team's seven runs. He's batted leadoff in both contests and is likely to stick there, with manager Pat Murphy looking to get the outfielder as many plate appearances as possible during the playoffs, per Curt Hogg of the Milwaukee Journal Sentinel.

Lara is not in the lineup for Game 2 of the NLDS against the Padres on Sunday.

The rookie outfielder went 0-for-3 with a walk in his playoff debut Saturday, but he'll take a seat for Game 2 versus San Diego ace Michael King. Sal Frelick will instead pick up a start in right field for Milwaukee while batting seventh.
