Roger Federer helps launch 2018 Laver Cup in Chicago

The Laver Cup was a hit last year, and now Roger Federer is hoping it proves popular on U.S. soil. The 20-time Grand Slam champion made his first-ever visit to Chicago on Monday to promote the second Laver Cup, a team competition that debuted last year in Prague. Federer, shaking off a three-set loss to Juan Martin del Potro on Sunday (18 March) in the final at Indian Wells that ended his 17-match winning streak, was joined by tennis legends Rod Laver and John McEnroe, along with young Australian star Nick Kyrgios. Federer's management team was instrumental in launching the Laver Cup, which pits Team Europe against Team World. After its third year, he said he'll entertain possible changes to the format.
