Buckingham Brown & Nichols School (Cambridge, Mass.) lefthander Andrew Chin, a Boston College commit, will undergo Tommy John surgery and miss the rest of the season, Baseball America learned Thursday.

A 6-foot-1, 180-pound lefty, Chin went 7-0, 0.78 with 68 strikeouts in 45 innings for BB&N as a junior. But Chin hadn’t thrown much this year as he nursed the elbow injury, and there had been some speculation that Chin would need surgery.

The injury won’t do much to temper the hype around this year’s class of high school hurlers from Massachusetts, which is considered historically strong, but it might affect Chin’s draft stock. Chin was rumored to be a tough sign before the injury, and now he won’t be able to throw for about 10-12 months. It wouldn’t be entirely unprecedented for a team to take a high school pitcher from the Northeast coming off an injury, though. Just last year the Indians selected Suffern (N.Y.) High righthander Robbie Aviles, who had a partial ligament tear and needed surgery, in the seventh round.

When healthy, Chin sat at 86-90 mph and touched 92 with his fastball, threw a fringe-average curveball and showed feel for a changeup. He had a deceptive delivery with a three-quarters release point and impressed talent evaluators with his ability to compete.

One national league scout told Baseball America that, if Chin fully recovers, he could be a top-three round selection after spending a few years at Boston College.
