I know the Oregon Ducks' logo is an O and an alternate logo for the Baltimore Orioles says "O's".
I think that may be it for major American sports (not sure though), but there's probably more in smaller or international leagues.

A noob looks like Stuart O.
Overstock .com has the big red O as its logo.
