Andy Murray is on the best run of his career despite his belief he's lost some speed.

Murray, who made history this month as the first player to successfully defend the Olympic gold medal, rides a career-best 22-match winning streak into today's Cincinnati final against 12th-seeded Marin Cilic.

The second-ranked Scot's court coverage is among the best in the sport, but Murray says he's slightly slower now than in his younger years.

"I have measured my speed over the years," Murray told the media in Cincinnati. "I'm not as fast as I was a few years ago, but I've not lost too much speed."

Still, the 29-year-old Murray's anticipation and ability to read the game make him quick off the mark.

"I'm not the fastest out of all players out tour, but I think my anticipation is what helps my speed," Murray said. "I anticipate where the ball is going to go pretty good from having played tennis from such a young age and played so many matches. That's what helps me, I think. My speed is good, but I'm not the fastest."

In a past interview with Tennis Now, Hall of Famer John McEnroe rated Gael Monfils, Murray, Rafael Nadal, Novak Djokovic, Kei Nishikori and Alexandr Dolgopolov as among the fastest players on the ATP Tour.

McEnroe named archrival Bjorn Borg as one of the fastest players he faced, credited Michael Chang for his unrelenting court coverage and also cited two-time Australian Open champion Johan Kriek as "a guy who doesn't get mentioned a lot, but Kriek was one of the fastest players of my generation."
