SAN FRANCISCO -- Veteran reliever Santiago Casilla, who has spent the entirety of his 15-year career in the Bay Area, was designated for assignment ahead of the A's second meeting with the Giants on Saturday.
A three-time World Series winner with the Giants, the 37-year-old Casilla was enjoying his second tour with the A's, who originally signed him out of the Dominican Republic in 2000 under the name Jairo Garcia. His playing time, however, was gradually diminishing in Oakland, and he subsequently endured command issues, walking 20 in 31 1/3 innings while posting a 3.16 ERA.
