Rory McIlroy has confirmed he will adopt a new cross-handed putting grip at the WGC-Cadillac Championship.
Four-time major winner McIlroy will tee it up alongside the only two players above him in the world rankings - Jordan Spieth and Jason Day - for the first two rounds of this week's tournament at Doral.
Spieth and McIlroy each missed the cut in their last outings, at the Northern Trust Open and Honda Classic respectively, but the latter is hopeful a change of putting technique will reap rewards in Florida.
Having posted a video to Instagram on Wednesday that showed him putting with his left hand below his right, McIlroy stated at a news conference: "It's a drill that I've been doing for a while, because I feel like my left hand sort of controls my putting stroke and that's the lead hand for me.
"I felt like over the past few weeks my right hand was becoming a little bit too dominant. I practised over the weekend with left below right and it felt really, really good so I'm going to give it a try this week and see where we go with it.
"It felt really good, the roll of the ball is really good, the contact is much better and it really just takes my right hand out of it and that's really what I wanted to do.
"Everything that I have done in my putting in the last few years is all to try and lead with the left hand and really just have the right on there as more of a guide than anything else. But I felt like my right hand was becoming a little bit too active in the stroke, so this is a perfect way to deactivate that."
McIlroy has managed four top-10 finishes in the WGC-Cadillac Championship, but is still seeking to win the tournament for the first time.
Assessing the challenge posed by the 'Blue Monster' course, he added: "It is a very risk-reward type of golf course. There's a lot of water and if you take it on and hit the right shots it can give you an advantage, but again you have to pick and choose your spots - where to be aggressive and where not to.
"There's four par-fives and you want to take advantage of those, but then the par-threes are tough. It's not just 'bombs away', but at the same time I think a little bit of length can give you an advantage."
