Why not call the slams "2000" then? It may be necessary for the marketing you know.
Pete Sampras holds the all-time record with 14 2000s. Many people also forget that he amassed a grand total of 5(!) WTFs.
That's right. 5 WTFs. It's incredible.
However the one minor blemish on his resume is that Sampras collected only 11 De Villiers ballsacks (formerly known as the masters series), a number long time ago surpassed by Federer.
