"Graf was ranked World No. 1 by the Women's Tennis Association (WTA) for a record 377 total weeks—the longest period for which any player, male or female, has held the number-one ranking since the WTA and the Association of Tennis Professionals began issuing rankings."

Steffi dominated an era when the MAJORITY of the top 20 ALL-TIME WTA players were active & still has a higher winning percentage than Serena plus more Grand Slam titles while having participated in the same amount of Grand Slam tournaments (Over their 18 year career, they both didn't participate 11 Grand Slam b/c of injury).

Serena being ranked #1 at age 32 being special is some ole' bullshyt. Let's be honest, Ivanovic/Wozy would have been cute ball girls in the 80s/90s & Sharapova would have never sniffed the #1 ranking.

Meanwhile Steffi was setting LEGIT records against LEGENDS of the sport DURING their PRIME at the conclusion of her 18th season (the same time span as Serena's debut & her so called record).

"At the 1999 French Open, Graf fought back from a set and twice from a break down in the second set to defeat the top ranked Hingis in three sets for a memorable victory. Graf also became the first player in the open era to defeat the first, second, and third ranked players in the same Grand Slam tournament by defeating second ranked Davenport in the quarter-finals and third ranked Monica Seles in the semifinals."
