Marmol and Volquez replace Chris Capuano and Paco Rodriguez from the bullpen. Volquez, a starter for the Cincinnati Reds for four seasons before moving to the San Diego Padres last season and eventually the Dodgers this season, has gone 0-2 thus far this season with a 4.18 ERA in five starts.
The Volquez move is likely due to injury concerns for Hyun-Jin Ryu.
On the other hand, the Marmol addition is more surprising due to the success of Capuano in the National League Division Series, throwing three shutout innings of relief against the Braves in Game three.
Marmol has had success with Los Angeles since coming over from the Chicago Cubs, holding a 2.53 ERA and 27 strikeouts in 21 appearances thus far.
While Rodriguez has sputtered lately with a 27.00 ERA in the NLDS against the Braves, giving up two runs in 2/3 innings, he has held a 2.21 career ERA.
The move also leaves the Dodgers with just J.P. Howell, who has not given up a run in three postseason appearances this year, as a left-hander in the bullpen.
The one point to be made about both of these players is they both have had recent success, albeit short-lived, but were essentially cast-offs from both of their former teams.
Volquez was acquired after being released by the Padres thanks to his 9-10 record and 6.01 ERA and Marmol was not getting the job done with the Cubs before coming over to L.A., blowing multiple saves before finally being put on waivers.
