Over the first 10 days of 2017, we're examining the Top 10 players on the ATP and WTA tours—how will they fare during the new season? All of the previews can be found here.
Like Kei Nishikori, Marin Cilic has followed in the late-blooming footsteps laid down by Stan Wawrinka and Andy Murray. At 28, the Croat is coming off the best year of his career. In 2016, he finished a career-high No. 6 and won two titles, including his first Masters 1000 in Cincinnati. Unlike in 2014, when he won the U.S. Open and then quickly faded, Cilic was a force throughout the season, right down to its closing weekend when he led Croatia in the Davis Cup final. Along the way, Cilic recorded wins over Murray and Novak Djokovic, and nearly topped Roger Federer at Wimbledon.
