Santiago Casilla designated for assignment by A’s
Reliever Santiago Casilla has pitched for a Bay Area team in each of the past 15 seasons, including this one. His tenure with the A’s apparently has come to an end. Amid several moves by Oakland on Saturday, the most significant was the team designating Casilla for assignment. Casilla, who turns 38 on July 25, has had two stints (2004-09, 2017-18) with the A’s, sandwiched around his time with the Giants (2010-16). The right-hander has a 3.16 ERA in 311/3 innings over 26 appearances this season.
