Raonic, Isner, Anderson and Karlovic are almost a given.
Chardy surprisingly averages over 100mph quite often.
Harrison, Dimitrov, Berdych and Federer hit second serves pretty fast, pretty sure they've averaged over 100mph on a few occasions.
Roddick if you count players that are still ranked.
Monfils on his crazy double-faulting spree at the Australian Open got close, averaging 98mph against Lu.
