Shin-Soo Choo has been shocking manager Manny Acta during his recovery process after having surgery on his left thumb at the end of June.

The original prognosis was that Choo would miss eight to 10 weeks, but just a little more than a month later, the outfielder took his first swings in the batting cage and immediately made an impression.

"I can't believe how quick of a healer this guy is," Acta said. "He seems a lot closer than we would expect at this point by the way I saw him swing the bat, so that's good news to us."
