Fleetwood comes into the WGC-Mexico Championship at a career-high of 11th in the world rankings after successfully defending his title in Abu Dhabi, finishing sixth in Dubai and fourth in last week’s Honda Classic.
The 27-year-old was a 200/1 outsider when he finished second at Chapultepec GC behind world number one Johnson 12 months ago, but is rated just a 16/1 chance to go one better this year.
“The year’s been great so far,” Fleetwood said.
“It was important, after having such a good year, to keep going, just like (Honda Classic winner) Justin Thomas has done this year.
“He just keeps progressing and that’s what you hope to do and what you’ve kind of got to do. So far so good, but you can never take your foot off the gas, you have to keep going.
“My game is getting better all the time. I’m consistently working hard and I feel like I’m always doing the right things. My confidence is up. You’ve still got to play well, but I think when you play well you have that belief in yourself that you can do the whole week and you can be there at the end and you can win.
“That’s the big thing. I’m just very, very comfortable with where I’m at and sort of my practice off the course, everything. Your performance is a result of your practice so everything I’m doing I just feel very confident that I’m doing the right things.”
Fleetwood will partner Masters champion Sergio Garcia and Sweden’s Alex Noren for the first two rounds in Mexico City, where 11 of last year’s top 20 were European.
“It is a very European layout,” Fleetwood added of the par-71 course which measures 7,330 yards, but whose highest point is more than 7,800 feet above sea level. “Last year it just reminded us of playing in Italy or some of the courses that we play.
“It’s a bit of an old-school golf course and one we’re kind of used to playing a little bit. It’s still different, it’s still a long way above sea level and the greens are a bit more slopey than what we’re used to, but the general feel when you’re walking down the fairways and seeing the tee shots is quite European.”
Forty five of the world’s top 50 are in the 65-man field competing for a prize fund of £7.2million and winner’s cheque of £1.2million, with Rory McIlroy, Hideki Matsuyama, Jason Day, Henrik Stenson and Brooks Koepka the players to miss out.
