The women's 100-meter butterfly event has a new world-record holder and her name is Dana Vollmer.

While it's shocking whenever a world record is broken during the Olympic Games, the American swimmer foreshadowed this event by recording a new personal-best time in the event when qualifying for the final.

Vollmer recently explained her strategy going into the qualifying round to Karen Crouse of the New York Times, stating:

I did feel like I was kind of pacing myself and building up to get faster...I like swimming fast in prelims and then fine-tuning instead of holding back.

Her strategy paid off in a historic way when she took to the pool in the finals, where she took down Sarah Sjostrom's record set back in 2009 at the World Championship in Rome.

Americans may all be familiar with Michael Phelps thanks to his performance at the last Olympic Games, and London might provide Vollmer with the opportunity to reach his same level of fame.

The female swimmer has already built quite a resume in her career, as she was a part of the 2004 800-meter relay team in Athens that broke the 17-year record held by the German Democratic Republic team.

Vollmer is also a part of the U.S. 400-meter medley relay team that set the second-best record in the event at the 2011 FINA World Long Course Championships.

This performance adds yet another redemptive story for Team USA's London scrapbook, as Vollmer took gold just four years after failing to qualify for the 2008 Games.

Perhaps Vollmer will swap redemption stories with Kelci Bryant, who was a part of the first ever silver medal duo for the U.S. in synchronized diving after finishing fourth in Beijing four years ago.
