US Open champion Marin Cilic said a pep talk in the locker room from coach Goran Ivanisevic helped him stay relaxed in the final.
Cilic said on Tuesday that before he went on court for his 6-3, 6-3, 6-3 victory over Kei Nishikori, Ivanisevic said to be sure to enjoy the title match - even if he was going to be incredibly nervous.
Speaking to a small group of reporters between TV appearances Tuesday, Cilic says his championship is "life-changing, completely" and he feels "like I was on a different planet."
Cilic is the first Croatian man to win a major title since Ivanisevic at Wimbledon in 2001. (Also read: Despite defeat, fans proud of Kei Nishikori)
