Driveline Mechanics, two days ago, took a look at Joba Chamberlain’s pitching mechanics. Their conclusion:

I think Joba’s injury concerns are well-founded. He has a lot of the classic signs of hyperabduction, rushing, hung arms syndrome, and a bad followthrough. That he does a few things right and is blessed with obvious genetic gifts does not make him a good bet to avoid serious injury in the future. Throw in some conditioning concerns and you have a legitimate reason to fear for Joba’s future.

I think I liked it better when people just wanted to debate his Brad “The Animal” Lesley routine after a strike-out to end an inning rather than have any possible discussion about Joba’s mechanics being flawed.

Best approach on this one, to me? Bookmark the observation and then wait and see. Could be something here…then again, it could be nothing too.
