As mentioned before, Bochy has said that the Giants need the most help in the bullpen. This season, Cishek has a 3.15 ERA, 32 strikeouts, 12 walks, and 14 saves in 34.1 innings of relief.
The Giants obviously don’t need a closer, but Cishek could be used as another right-handed setup man along with Santiago Casilla. While Casilla has been out, the Giants have used right-handers such as Sandy Rosario, George Kontos, and Jake Dunning. These three have been inconsistent, and the addition of a solid right-handed relief pitcher would take some pressure off of these young pitchers.
The Giants have had success acquiring solid relief pitchers at the trade deadline before. They acquired both Javier Lopez and Ramon Ramirez in 2010, and both of them contributed greatly to the Giants’ 2010 World Series title.
Also, Cishek wouldn’t be an expensive addition, since he’s making $505,000 this year, and he’s arbitration-eligible in 2014. The Marlins would most likely agree to a deal that wouldn’t involve a lot of highly touted prospects either.
