Slusser Reports:
- Now top pitching prospect Michael Ynoa, the 17-year-old sensation from the Dominican Republic, is out of action because of elbow soreness.
- According to assistant general manager David Forst, Ynoa had an MRI exam last week that will be reviewed by Drs.
- Ynoa had been doing a throwing program at the A's minor-league complex in Phoenix and there was hope he would pitch in the Arizona Rookie League this summer.
- "We're in the process of determining how severe it is," Forst said.
