When asked how much further she felt she could go by Evert, Williams replied: “Well, it's no secret. I'm going for the gusto. I'm going to try to catch up with Steffi. But right now I'm really focused on 19, which will begin in Australia. Whether I get there or not, I don't know. But I know if I get to 19, the second it happens I will be thinking of 20.”

Williams struggled in 2014, failing to get to the quarterfinals of the year’s first three majors, but she regrouped in New York to win her 18th major title, which tied her with Evert and Martina Navratilova on the all-time title list.

Williams tells Evert that she’s got big plans for 2015, which include ramping up her serve. “I want to move a lot faster on the court,” she said. “I want to be more dynamic and just completely awesome out there. And I need to bring my serve back. My serve in 2014 was a little disappointing for me. I want my 2013 serve back, but a better version of that for 2015. I had so many double faults this year: I was hitting, like, seven in a match, and it was driving me insane.”
