Casilla, who started Wednesday's 15-11 Cactus League loss to the Cubs due to Kendall Graveman being scratched with an illness, gave up five earned runs on two hits and two walks over just one-third of an inning.
Graveman (illness) was scratched from Wednesday's major league spring start against the Cubs and instead faced minor-leaguers at A's camp at Hohokam Park, Jack Thompson of the East Bay Times reports. "He was sick yesterday," manager Bob Melvin said before Wednesday's game. "He's better today, but it was going to be a shorter day for him anyway. Based on the fact he didn't feel great it's better for us to monitor his innings."
