Rory McIlroy was passed by Jordan Spieth in the Official World Golf Ranking in 2015. Now in 2016, McIlroy appears to be trying to get back on top by stealing a move by golf’s current No. 1.

On Wednesday, McIlroy posted this video of him practicing his putting ahead of this week’s WGC-Cadillac Championship. Look closely and see if you notice anything different in the four-time major winner’s stroke:

McIlroy is putting cross-handed, or left-hand low. It’s the way Spieth, widely considered the game’s best putter, rolls in so many putts.

Rory has never been considered one of the game’s best putters (he ranks a dismal 189th in strokes gained/putting in four events this season), but he sure is rolling them nicely in that video. Again, though, we’re talking about practice. We’ll have to wait and see if — and how well — McIlroy uses the new method in competition. He tees off at Doral with Jason Day and yep, Jordan Spieth, on Thursday morning.

UPDATE: Rory McIlroy confirmed on Wednesday that he will use a left-hand low putting style in the WGC-Cadillac Championship.

“It’s a drill that I’ve been doing for awhile because I feel like my left hand sort of controls my putting stroke, and that’s the sort of lead hand for me, and I felt like over the past few weeks, my right hand was becoming a little bit too dominant,” McIlroy said.

“I practiced over the weekend just with left below right and it felt really, really good. I’m going to give it a try this week and see where we go with it. But it felt really, really good. Roll of the ball is really good. The contact is much better, and it really just takes my right hand out of it.”

For now, McIlroy, who only needs the Masters to complete the career grand slam, is intent on sticking with this altered putting method.

“I feel like it’s something I’m going to stick with regardless of what the outcome is tomorrow or this week or next week,” he said. “I really do feel like it helps me put a stroke on it that I want to. It’s a great feeling. I feel like it gives my putting stroke a bit more of a better rhythm, as well, a better flow. Yeah, look, if it doesn’t work right from the get-go tomorrow, you’re not going to see me on Friday morning putting conventional again. It’s something I’m going to stick with for awhile.”
