Owies

Two closers on contenders have boo-boos:

Billy Wagner is having his shoulder examined later today; and

Kerry Wood is heading to the DL with a blister on his finger.

Neither of these seem serious at first blush -- Wagner's is obviously a scarier thing -- but if one or both of these guys miss extended time, whoever doesn't panic and do something like sign Joe Borowski will have the inside track on the NL pennant.
