An "emotional" Rafael Nadal on Monday said he watched spellbound as Tiger Woods rolled back the clock to win a fifth Masters title and cap his comeback from back surgery.

Spain's World No. 2, a keen golfer himself, expressed nothing but admiration for Woods, who has fought through at least as many physical challenges as he has himself. "It was amazing," Nadal said as he prepared for his Wednesday start at the Monte Carlo Masters, his first event in a month since withdrawing with knee issues at Indian Wells.
