The case for Serena Williams
Serena Williams won her first major at the 1999 US Open at age 17 and her 23rd — the Open Era record for any player, man or woman — at the 2017 Australian Open while roughly eight weeks pregnant. Between those bookends lies the most sustained excellence in women's sports history: 23 Slam finals won from 33 contested, 319 weeks at No.1 including a 186-week consecutive run that tied Steffi Graf's record, four Olympic gold medals, and two separate 'Serena Slams' (holding all four majors at once) completed eleven years apart, in 2002-03 and 2014-15. She won majors as a teenager and in her mid-thirties, beat No.1-ranked opponents across three different decades, and returned from a 2011 pulmonary embolism to compile arguably her best stretch, going 3.5 seasons from 2012 with a match record above 90 percent. Her serve is widely considered the greatest shot in the history of women's tennis. On dominance relative to field, she has a case for the top spot on any list.
The case for Pete Sampras
Sampras retired with what was then the men's all-time record of 14 majors, and the record most likely to survive the Big Three era is still his: six consecutive year-end No.1 finishes, 1993 through 1998, a run of sustained supremacy no man has matched before or since. His seven Wimbledon titles in eight years (1993-2000) were built on the most complete serving game the sport had seen — not the fastest serve, but the best-disguised, backed by a second serve routinely rated the greatest ever and an attacking all-court game that made him nearly unbreakable on fast surfaces. He spent 286 weeks at No.1, won 64 titles, and ended his career with a perfect exit: winning the 2002 US Open, beating Agassi in the final, and never playing another match. The gap in his record — no Roland Garros, with just one semifinal there — is why he sits near the bottom of this list rather than the middle; on everything but clay, he was the standard his successors chased.
