Free-agent closer Mark Melancon has multiple offers of four years and $60-plus million on the table, according to FOX Sports' Ken Rosenthal. The Giants, Nationals and possibly one other team have reportedly made those offers to the right-hander, who turns 32 in March.

San Francisco is thought to be the front-runner for Melancon, who is one of three elite closers on the market along with Kenley Jansen and Aroldis Chapman.
