With the 2018 MLB opening day just a few days away, teams are starting to finalize their rosters for the 2018 season. The defending World Series champion Houston Astros have announced who will be on their 25-man roster when the season begins.

Catcher (3): Brian McCann, Evan Gattis, and Max Stassi. Stassi will serve as Brian McCann's primary backup, with Evan Gattis getting most of his at-bats at designated hitter.

Infield (5): J.D. Davis, Jose Altuve, Alex Bregman, Carlos Correa, and Marwin Gonzalez as a utility player.

Outfield (4): George Springer, Josh Reddick and Jake Marisnick, and Derek Fisher

Starting pitcher (5): Justin Verlander, Dallas Keuchel, Lance McCullers Jr., Gerrit Cole and Charlie Morton will line up in that order to start the season as expected.

Relief pitching (8): Tony Sipp won the final bullpen spot earlier this week. He'll join Ken Giles, Chris Devenski, Will Harris, Joe Smith, Hector Rondon, Brad Peacock and Collin McHugh in the bullpen.
