The Dodgers made a pair of tweaks to their roster from the NLDS round to the NLCS, removing left-handers Paco Rodriguez and Chris Capuano in favor of righties Carlos Marmol and Edinson Volquez.
The decision to drop Rodriguez was a relatively easy one, despite his terrific rookie season. The 22-year-old had a 1.88 ERA in 64 appearances heading into September, but he went 0-2 with a 5.68 ERA in 12 appearances over the season's final month.
Those struggles continued in the NLDS, as he allowed four hits and two runs in 0.2 innings of work over two appearances. Meanwhile, Marmol turned things around after coming over from the Chicago Cubs, with a 2.53 ERA and 11.4 K/9 in 21 appearances for the Dodgers.
The removal of Capuano was a head-scratcher, though. The veteran southpaw threw three scoreless innings in relief of Hyun-Jin Ryu in Game 3 of the NLDS to earn the victory, and given the fact that the Cardinals hit just .238 against lefties on the season, he looked like a candidate to earn the Game 4 start.
Instead, the team opted to go with Volquez, who had a 5.71 ERA on the season and a 4.18 ERA in six games (five starts) after joining the Dodgers. He posted a 6.55 ERA in two starts against the Cardinals this season.
