The Orioles and Rangers will be meeting in the postseason for the first time since 2012, a Wild Card game in which Baltimore prevailed 5-1.

Rangers starter Max Scherzer has been left off the team's ALDS roster due to a shoulder injury, although there is a possibility that he could return if Texas makes it to the Championship series (via USA TODAY's Bob Nightengale).

The only other change was replacing Grant Anderson in the bullpen with Cody Bradford, who posted a 5.30 ERA in 20 appearances this season.

As for the Orioles, starting pitcher John Means has been left off their ALDS roster due to elbow soreness. However, manager Brandon Hyde expects him to be available for a potential ALCS appearance (via Nathan Ruiz of The Baltimore Sun).

In the matchup of the 2-seed Astros and 3-seed Twins, both teams' rosters are relatively healthy heading into their ALDS matchup.

Minnesota outfielder Byron Buxton is still out due to a knee injury, as the 2022 All-Star was unable to return in time despite taking live batting practice yesterday.

The two NL East rivals are set for a rematch of last year's ALDS, a series that Philadelphia won 3-1 before their eventual National League pennant run.

Phillies pitcher Michael Lorenzen is back on the active roster after being left off for their Wild Card series against the Miami Marlins, while utility player Weston Wilson was the odd man out.

Meanwhile, Braves right-hander Kyle Wright was placed on the 60-day IL with a right shoulder strain, so he'll miss the remainder of the postseason. Reliever Jesse Chavez and infielder Luke Williams did not make the roster, either.

Los Angeles Dodgers

Pitchers: RHP Ryan Brasier, LHP Craig Fergusen, RHP Brusdar Graterol, RHP Michael Grove, RHP Joe Kelly, LHP Clayton Kershaw, RHP Lance Lynn, RHP Shelby Miller, RHP Bobby Miller, RHP Ryan Pepiot, RHP Evan Phillips, RHP Emmet Sheehan, LHP Alex Vesia

Infielders: Freddie Freeman, Enrique Hernandez, Max Muncy, Miguel Rojas, Chris Taylor, Kolten Wong

Outfielders: Mookie Betts, Jason Heyward, James Outman, David Peralta

Catchers: Austin Barnes, Will Smith

Designated Hitter: J.D. Martinez

As the Dodgers prepare to host the Diamondbacks, they've set their official ALDS roster.

Second baseman Kolten Wong made the roster after hitting an even .300 during his 30 plate appearnces with Los Angeles. Infielder Amed Rosario was left off.

Lefty pitcher Ryan Yarbrough didn't make the cut, likely replaced by Michael Grove after the 26-year-old right-hander didn't allow an earned run in any of his final four appearances in the regular season.

Arizona Diamondbacks

Pitchers: RHP Miguel Castro, RHP Luis Frias, RHP Zac Gallen, RHP Kevin Ginkel, RHP Merrill Kelly, LHP Joe Mantiply, RHP Ryne Nelson, LHP Kyle Nelson, LHP Brandon Pfaadt, LHP Andrew Saalfrank, RHP Paul Sewald, RHP Ryan Thompson

Outfielders: Corbin Carroll, Tommy Pham, Alek Thomas, Lourdes Gurriel Jr.

Catchers: Jose Herrera, Gabriel Moreno

The Diamondbacks are sending out a roster that is extremely similar to the one they used during their Wild Card victory over the Milwaukee Brewers.

One notable change is the addition of lefty Kyle Nelson, who will replace rookie Bryce Jarvis. Although Jarvis was on Arizona's Wild Card roster, he did not make an appearance during their two-game sweep.
