2013 was a big year for former Stanford star and 2010 NCAA champion Bradley Klahn, who won two singles titles during the year – the Aptos, Calif., Challenger and the Costa Mesa, Calif., Futures – and was the men's top prize-money winner, earning $50,606. Klahn, who reached five singles finals in all in 2013, earned a wild card into the 2013 US Open based on his summer hard-court USTA Pro Circuit results, which included his win in Aptos. He broke into the Top 100 of the ATP rankings for the first time in his career in November and is currently ranked No. 97, up 153 spots from his 2012 year-end ranking of No. 250.
