No need.
And if you're using O2 absorbing caps...do not pre-sanitize. The first liquid contact those caps should have is with your bottled beer.
Actually this isn't exactly true...On Basic brewing a few weeks back the host contacted the maker of Oxygen Absorbing Caps (Crown Beverage), and actually recommended you santize them quickly, evidently the "Oxygen Absorbing Effect" of the caps is not immediate and they need to be wet for a period of time before the magic happens, like days.

They recommend sanitizing ONLY the caps you are using, and sanitizing just before bottling.
Me personally, I sanitize....the beer is going to be moved from your bottling station to where you are going to be storing them, you are bound to be sloshing them a bit, it is inevitable that your beer will come in contact with the cap. (We often have recommended to roll the bottles back and forth to re-suspend the yeast if they aren't carbing.)
So I really don't see why you wouldn't sanitize the caps...to me it's not worth the risk NOT to.
Here's a thread we put together of tips to make bottling easier.

Plus in the case of commercial breweries, don't they
pasturize the beer after it has been bottled? So everything is getting sanitized?
