I recall that Sampras averaged 115mph on second serves in his 2001 US Open no-breaks QF victory over Agassi. Then he averaged 85mph against Hewitt in the final. I suspect it had something to do with the back-to-back SF-F format. If it weren't for that, I think Sampras probably would have shown up with his full-strenght 2nd serve and handled Hewitt no problem.
