Looking ahead to the 2015-16 San Francisco Giants free agents

RHP Santiago Casilla

Despite all of the criticism, since taking over the closer role in the middle of the 2014 season, Casilla performed well above average as he has posted a 2.56 ERA with 51 saves and has blown just 6 save opportunities in 97 games.

Should San Francisco retain Casilla? Yes.

With that being said, either via free agency or trade, I want San Francisco to pursue a closer this offseason. Such names include Joakim Soria and Tyler Clippard. Casilla has proven to be an incredibly solid bullpen arm who just seems to get the job done. Nevertheless, he is not fearful to opposing hitters. Not many hitters fear Casilla and I have been supporting a trade for a dominant closer, such as Craig Kimbrel, for some time now. A much older 35-year-old Casilla will be looking for a 2-3 year contract, worth about $4 million per year, and I think he, Sergio Romo, and Javier Lopez would make a great 7th and 8th inning combo.
