A’s reportedly sign former Giants closer Santiago Casilla

Santiago Casilla will not return to the San Francisco Giants in 2017. But the relief pitcher is reportedly close to a deal that would keep in the the Bay Area with the Oakland Athletics.

Casilla pitched with the A’s from 2004-09. He struggled in Oakland, posting a 5.11 ERA and 1.578 WHIP, striking out only 7.7 batters per nine innings.

Going to the Giants in 2010 seemed to turn his career around. In San Francisco, he had a 2.42 ERA, 1.16 WHIP and struck out 8.3 hitters per nine innings. He was one of only nine players to be a part of the 2010, 2012, and 2014 World Series championship teams. Casilla split closing duties with Sergio Romo in 2012, saving 25 games. He regained the closer’s job in 2014, saving 19 games. Casilla added 38 and 31 saves in 2015 and 2016.

The 2016 season was a disaster for Casilla, though. He was arguably the shakiest member of a shaky bullpen, blowing nine saves. Still, Casilla had respectable overall numbers with a 3.57 ERA, 1.19 WHIP and 10.1 strikeouts per nine innings.

If nothing else, the A’s have certainly loaded up on potential trade chips this offseason. Casilla joins Rajai Davis, Trevor Plouffe, and Matt Joyce as Oakland’s offseason signings.
