ST. LOUIS (AP) -- Washington Nationals reliever Daniel Hudson was placed on the postseason paternity list Friday and won't be available to pitch at the beginning of the NL Championship Series against St. Louis.
Right-hander Wander Suero will be on Washington's active roster until Hudson returns. Hudson, who has two saves and a win during the playoffs, is permitted to be away from the team for a minimum of one day and a maximum of three days. When he rejoins the Nationals, he will take Suero's spot.
Major League Baseball approved the roster substitution and announced it hours before Game 1 in the best-of-seven series at Busch Stadium.
Hudson's absence weakens a shaky Washington bullpen that had the worst ERA in the National League at 5.66. The right-hander went 3-0 with a 1.44 ERA and six saves in 24 regular-season appearances for the Nationals after he was acquired from Toronto at the July 31 trade deadline. He's pitched in four playoff games this month against the Brewers and Dodgers, throwing 3 2/3 scoreless innings with five strikeouts.
Suero was 6-9 with a 4.54 ERA and one save in 78 games this season. He made one appearance in the Division Series victory over the Dodgers, getting one out but giving up a run and two hits.
The Cardinals went with 12 pitchers and the same roster they used in the Division Series against Atlanta.
The only notable exclusions for St. Louis again were right-handers Michael Wacha and John Gant. Wacha is recovering from a strained shoulder. Gant went 11-1 with a 3.66 ERA this year, but the reliever struggled down the stretch.
