From Lance’s Blog:
Alonso to the DL
From Jamie Ramsey of the Reds
1b Yonder Alonso (Carolina) broke his right hamate bone (a hand bone) yesterday in the nightcap of a doubleheader at Tennessee when he swung at a pitch….he has been placed on Carolina’s DL.
Guess now we know why Spotlight Player Logan Parker replaced him in last night’s game.
UPDATE: This morning’s Enquirer (6/20) is reporting that Alonso will “probably have surgery and be out at least 6 weeks.”
It also has some info on Reds #1 pick Mike Leake, who reportedly was going to be shut down with tendinitis, but threw Friday night for Arizona State.

While Lance and others keep saying hand bone, the hamate is more wrist than hand. Its not good for power anytime soon, as its known to sap a players power for about a year after its healed. No long term issues are likely though.
Ouch, Doug, that’s rough.
I changed my mind then, don’t call him up
Surgery for this actually is a good thing, it makes it heal faster. Conservative recovery is 6-8 weeks, but with the surgery he will be rehabing quicker than without it.
