Who has the best overall winning record in the 21st Century?
The answer is VENUS WILLIAMS!
Since 2000 began Venus has won 4 GS majors, 19 titles out of 34 tournaments entered (a phenomenal winning % of .559!); has an incredible overall match record of 144-15 or .906; has a combined record of 55-11 or .833 against all top 10 players (including a combined record of 16-2 against Davenport, Hingis, and Capriati, 17-2 against Seles, Henin and Mauresmo, and 9-5 against Clijsters, Dokic, and Serena. Furthermore no player has beaten Venus more than ONCE since 1999 except Serena who has the ONLY winning record against her sister during the past 32 months and even it is a mere 3-2 (by constrast Serena has won 33 fewer matches than her sister and lost 4 more matches than Venus, has won 8 fewer titles, and 2 fewer GS majors since the new century began). Venus also has a better head-to-head record overall against other top 10 players.
It should also be pointed out that Venus has the best winning percentage record in the WTA overall for GS majors, tour titles, and matches during this time period.
I mention these facts because far too many fans, media analysts, and players alike are strangely not truly acknowledging who has been the finest and most dominant player over the past three years, and because many people now seem to have the severely mistaken idea that Venus will merely be tennis roadkill for Serena from this point onward. However nothing could be further from the truth...
