"Especially after today with the way I felt, the way my command was, I 100 percent believe I can get big league hitters out right now," Chamberlain said. "That's half the battle, saying you can do it. We're over that hump. I felt like today was my best day, overall." Chamberlain dislocated his right ankle bouncing on a trampoline with his son on March 22 and expects to see game action within two weeks. The right-hander was coming back from elbow ligament-replacement surgery at the time of the ankle injury.
