Athletics sign Santiago Casilla to 2-year, $11 million deal

The Athletics have agreed to a 2-year, $11 million deal with reliever Santiago Casilla, as first reported by Robert Murray of FanRag Sports. The contract includes $3 million in incentives based on games finished, pushing its overall maximum value to $14 million.

Casilla is the third free-agent addition of the last two weeks for the A’s, who also added Rajai Davis and Trevor Plouffe on one-year deals. With Oakland not being expected to contend next season, the additions may prove most valuable as trade chips at next summer’s non-waiver deadline.

Casilla, 36, returns to Oakland, where he spent six years from 2004 to 2009 before shifting to the Giants for the past seven seasons. He pitched to a 3.57 ERA while saving 31 games for the Giants last season, upping his total to 123 saves in seven years with San Francisco.

Casilla joins Ryan Madson, Sean Doolittle, John Axford and Ryan Dull in Oakland’s bullpen mix, though it’s currently unclear who will take over ninth inning duties.
