Federer is such a dominant number one, standing head and shoulders above everyone else, that people sometimes forget that number ones in previous years would often be humbled. I am just wondering, how many times number one players have gotten bagelled. I know of two instances: Haas beat. Agassi 6-0, 6-7, 6-4 (Grand Slam Cup 1999) Enquist bt. Agassi 6-3, 4-6, 6-0 (Euro Card Open 1999) I am pretty sure Sampras never got bagelled while at the top. Maybe Hewitt, Rios, Kafelnikov, Rafter, Muster but the chances are low since besides Hewitt none of these stayed at the top for long.
