Did you know that International Women’s Day, celebrated annually on March 8, was originally called International Working Women’s Day? So we want to salute those women who have worked long hours on their fields of play. First up, Skylar Diggins, who on Monday played all 55 minutes, a school record, in Notre Dame’s triple-overtime win over Connecticut. Then there’s Jiyai Shin, who went nine playoff holes (over two days) to beat Paula Creamer at the 2012 Kingsmill Championship to end the longest sudden-death playoff between two players in LPGA Tour history. Finally, here’s to Francesca Schiavone, who played a Grand Slam-record 4 hours and 44 minutes to beat Svetlana Kuznetsova and advance to the Australian Open quarterfinals in 2011. To put that in perspective, Paula Radcliffe could have finished two marathons in that amount of time, provided she kept her world-record pace from the 2003 London Marathon of 2 hours, 15 minutes and 25 seconds.
