Things change pretty quickly in the baseball world. Think back to the San Francisco Giants’ bullpen during the 2014 World Series run. The “Core Four” was still in place, with veteran righties Santiago Casilla and Sergio Romo combining with left-handers Jeremy Affeldt and Javier Lopez to create a lockdown group of relievers.
But things have changed in just the two years since then. Affeldt retired after the 2015 season, and Casilla, Romo, and Lopez are all free agents and it looks more and more likely that none of the three will wear the orange and black again.
