Three players in the traveling party will not be active -- reliever Logan Ondrusek, starting pitcher Mike Leake and catcher Devin Mesoraco. That means Cincinnati will go with rookie reliever J.J. Hoover and long man Alfredo Simon, while deciding not to keep a third catcher in Mesoraco.
Ondrusek was 5-2 with a 3.46 ERA in 63 appearances this season. But he struggled down the stretch with a 5.02 ERA over his final 16 games with nine walks and 18 hits over 14 1/3 innings.
Mesoraco, the Reds' top prospect entering the season, struggled in a backup role and batted .212 with five home runs in 54 games. He was demoted to Triple-A Louisville on Aug. 23 and has had only three at-bats since returning as a September call-up -- and none since Sept. 10.
Here is the breakdown of the Reds' NLDS roster:
Catchers: Ryan Hanigan, Dioner Navarro
Infielders: Joey Votto, Brandon Phillips, Scott Rolen, Zack Cozart, Todd Frazier, Miguel Cairo, Wilson Valdez
Outfielders: Ryan Ludwick, Drew Stubbs, Jay Bruce, Chris Heisey, Xavier Paul
Starters: Johnny Cueto, Bronson Arroyo, Mat Latos, Homer Bailey
Relievers: Aroldis Chapman, Sean Marshall, Jonathan Broxton, Sam LeCure, Jose Arredondo, Hoover, Simon
