#2 Marin Cilic
Many believe Marin Cilic hasn’t done justice to his talent. The Croat was the runner-up at the 2017 Wimbledon, in which the 30-year-old lost his way because of an injury.
Cilic was a runner-up at the Australian Open last year, losing to Roger Federer in the final. He also won the Queens Club championships where he defeated Novak Djokovic in the summit clash.
The 2014 US Open champion has stated that doing well in the Kremlin Cup will give him a much-required boost for the upcoming tournaments and the Grand Slam events next year.
Cilic was a part of the Croatian team that won the Davis Cup final by beating France 3-1 last year. His sublime baseline play has always unsettled his opponents, and that combined with his powerful serve makes him a really difficult opponent to face.
