Serena Williams has won back-to-back Grand Slam titles for the first time since she completed a “Serena Slam” and after major setbacks the past two years, she is talking about smashing some records.

Williams outlasted World No. 1 Victoria Azarenka 6-2, 2-6, 7-5 on Sunday to win her fourth US Open crown, becoming its second-oldest Open-era winner at age 30, and a 15th Grand Slam title, seven shy of Steffi Graf’s all-time record.
