The Chicago Cubs are preparing to begin their postseason on Friday night when they host the San Francisco Giants at Wrigley Field, and on Friday morning they unveiled their 25-man playoff roster. 

Here are the names of the players who made the team for the first playoff series:

Catchers: Willson Contreras, Miguel Montero, David Ross

Infielders: Javier Baez, Kris Bryant, Tommy La Stella, Anthony Rizzo, Addison Russell, Ben Zobrist

Outfielders: Albert Almora Jr., Chris Coghlan, Dexter Fowler, Jason Heyward, Jorge Soler

Pitchers: Jake Arrieta, Aroldis Chapman, CJ Edwards, Justin Grimm, Kyle Hendricks, John Lackey, Jon Lester, Mike Montgomery, Hector Rondon, Pedro Strop, Travis Wood

If the Cubs advance to the next round, they can tweak their roster, and it would appear likely that they would add at least one more pitcher to the mix, as the NLCS is a best-of-seven series rather than a best-of-five.

The Giants also named their roster on Friday morning:

Catchers: Trevor Brown, Buster Posey

Infielders: Brandon Belt, Brandon Crawford, Conor Gillaspie, Eduardo Nunez, Joe Panik, Kelby Tomlinson

Outfielders: Gregor Blanco, Gorkys Hernandez, Angel Pagan, Hunter Pence, Denard Span

Pitchers: Ty Blach, Madison Bumgarner, Santiago Casilla, Johnny Cueto, George Kontos, Derek Law, Javier Lopez, Matt Moore, Sergio Romo, Jeff Samardzija, Will Smith, Hunter Strickland
