• Melvin said Tommy Milone, who was skipped in the rotation because of multiple rainouts this week, would throw to Minor Leaguers in Arizona on Sunday before making his A's season debut on Friday.
"It's been a while since he's pitched," Melvin said. "I think it'll be good for him to face some hitters, and he'll be that much more ready for his next start on Friday."
• Right-handed starter A.J. Griffin will stay in Oakland to rehab his injured elbow while the A's travel to Minnesota for the season's first road trip. Melvin estimated it would be a week or two before Griffin resumed throwing.
"He's just going to start his strengthening here soon," Melvin said. "Up until this point it's been rest, but now he'll start the strengthening portion of it."
