In August, 1987, Bulgaria's Ginka Zagorcheva ran the women's 100-meter hurdles in 12.25 seconds, breaking the world record of 12.36, set by Grazyna Rabsztyn of Poland in 1980.
A year later, Zagorcheva's Bulgarian teammate Yordanka Donkova eclipsed her record with a time of 12.21 seconds.
Donkova's world record has stood for a quarter century, and is one of 11 women's track & field records still remaining from the controversial 1980s, when athletes from eastern Europe dominated international competition.
Since then, only a handful of athletes have seriously challenged Donkova's mark. Russia's Ludmila Narozhilenko ran a 12.26 in 1992, while Australia's Sally Pearson posted a time of 12.28 in 2011. The best American effort came from Gail Devers, who ran the 100 hurdles in 12.33 seconds in 2000.
Devers' American record stood until Saturday, when Clemson's Brianna Rollins sent shock waves through the world track & field community by running a time of 12.26 seconds at the U.S Championships in Des Moines, Iowa.
For Rollins, fresh off a pair of collegiate-record performances two weeks earlier at Eugene, Ore. and competing in her first meet as a professional, it was her 20th consecutive victory. Her time was the world's fastest since Narozhilenko ran her 12.26 twenty-one years ago.
Rollins' progression is, itself, stunning. Before beginning her 2013 outdoor season at Clemson, Rollins' best time in the 100 hurdles was 12.70.
Even more remarkable is Rollins' height - she stands just 5-feet, 5-inches - and age - she's 21, still two months shy of her 22nd birthday.
She bucks the trend on both fronts.
Donkova, Zagorcheva and Narozhilenko all stand 5-9. Pearson, who will challenge Rollins in the upcoming World Championships, is also an exception to the rule at 5-6. Devers, at 5-2, defied the odds in claiming her American record in 2000.
In age, Rollins is the youngest member - by nearly four years - of the world's all-time top 10.
Donkova was 27 when she set the world record. Devers was 34 when she set the American record. The average age of the others on the world's top-10 list is 28.3 years.
Rollins says she doesn't think about setting records. Her focus is on her next race, her next hurdle, her next stride.
But it doesn't take an expert on the mechanics of hurdling to see that Rollins has the ability to run even faster than she ran on Saturday.
Unlike her nearly-flawless run in the winning the NCAA title two weeks ago, Rollins' record breaking run on the U.S. Championships was anything but clean.
Her start was unspectacular, and she touched at least five hurdles, hammered one, and still posted the third fastest time in world history.
"I don't think about records," said Rollins following her record run. "I came out here and did what I have to do.
"I just came out here and tried to focus on my own lane."
A world away, Rollins grabbed the attention of reigning Olympic champion Pearson, who posted on her Twitter account: "Looks like I am bringing my A++ game to worlds this year with Brianna Rollins just running 12.26."
It should be quite a match-up when they chase Donkova's record at Moscow in August.
