On Monday, the pitching schedule was posted in the clubhouse at Bright House Field. It said that Cole Hamels would face hitters in a live bullpen session for the first time this spring on Thursday.

Thursday arrived, and it wasn't the persistent rain showers that cancelled the throwing session. Hamels was simply not strong enough to throw.

After throwing three bullpen sessions in his quest to join the Grapefruit League rotation in mid-March, Hamels suffered a setback on Saturday when he said his body felt fatigued after throwing off the mound.

"I believe I threw 35 pitches," Hamels said. "To my body it felt like a thousand."

Hamels won't throw off the mound again until next week. Originally, it was asummed Hamels would be able to join the rotation after missing just a start or two in April.

That timetable has changed.
