After blowing 32 saves during 2016, including two in the postseason, the San Francisco Giants knew they had one glaring need to address over the offseason; the closer role. The Giants have not had a true closer since Brian Wilson left following an injury ridded 2012 season. Since then they have rolled out the likes of Sergio Romo, and Santiago Casilla, before Bruce Bochy opted to close games by committee towards the end of the 2016 season.
The Giants addressed this major issue over the offseason by signing one of the premier closers in the MLB in Mark Melancon to a 4 year $62M contract.
