Cole Hamels said he won't throw off the mound for at least another week after suffering from fatigue following his latest throwing session.

The left-hander entered camp behind schedule after dealing with biceps tendinitis that began in November.

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

Hamels went 8-14 with a 3.60 ERA in 33 starts last season.
