Reds go with four starters, two catchers on roster

SAN FRANCISCO -- Hours before beginning their National League Division Series against the Giants on Saturday at 9:30 p.m. ET on TBS, the Reds set their 25-man roster.

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.

Reds vs. Giants
Leake, the Reds' fifth starter this season, was hoping to make the club as a long reliever and potential pinch-hitter. In 30 starts, he was 8-9 with a 4.58 ERA in 179 innings while batting .295 with two home runs.

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
