OAKLAND, Calif. -- The Oakland Athletics have released veteran reliever Santiago Casilla, five days after he was designated for assignment.
The A's made the move Thursday.
Casilla is 42-31 with 144 career saves in 15 seasons, but has been up and down with the A's this year while having control issues. Used primarily in middle relief, the right-hander has a 3.16 ERA despite 20 walks and four hit batters in 31 1/3 innings. He turns 38 next week.
Casilla made his major league debut in 2004 and spent his first six seasons with the A's before signing with San Francisco in 2010.
