33 – Sets played in a month by American junior Lauren Davis (of which she won 32) en route to winning the Girls 18s singles championship at the 2010 Dunlop Orange Bowl and earning a 2011 Australian Open wild card – an impressive performance and workload for a junior player, with 21 matches in 28 days. The Ohio native won 25 sets in a row and had won her two previous junior tournaments before being forced into a three-set thriller in the Orange Bowl final with fellow American Grace Min. Two days after the tournament, Davis would travel from Key Biscayne to Atlanta and eventually best 2010 US Fed Cup team member CoCo Vandeweghe in straight sets, 6-2, 6-2 to earn the bid to Melbourne.
