MESA — Oakland A’s pitcher Santiago Casilla has seen a lot in his 14-year major-league career.
At 37, he is the team’s oldest player, rejoining the A’s in 2017 after a seven-year stint in San Francisco, where he secured three World Series rings. When he returned, he wasn’t the 29-year-old who left them but a man determined to bring what he learned with the Giants across the bay.
“The big thing was just having a vision for what you want to do, how you want to be successful,” Casilla said through the translation of A’s PR director Fernando Alcala.
