OAKLAND – The A’s finalized their deal with Santiago Casilla Friday morning, adding the former Giants closer to a bullpen that could be the club’s strength in 2017.
He agreed to a two-year contract and figures to get setup duty behind closer Ryan Madson along with right-handers John Axford, Liam Hendriks, and Ryan Dull and lefty Sean Doolittle.
Casilla, who came up with the A’s but who came into his own with the Giants, winning three World Series rings, is the fourth free agent the A’s have added this winter, joining outfielders Matt Joyce and Rajai Davis and third baseman Trevor Plouffe.
