Roger Federer

Roger Federer, who regained the world Number One ranking last month, is on a quest to make history in the California desert by winning an unprecedented sixth Indian Wells title. The 36-year-old Swiss marvel continues to defy the aging process, claiming his 20th Grand Slam title and sixth Australian Open crown in January. He has enjoyed a perfect start to 2018 by winning both events he has competed in and taking his career singles title tally to 97. "He shows there is no limit," said third-seeded Grigor Dimitrov on Wednesday.
