Rory McIlroy has joined World No. 1 Jordan Spieth as a cross-handed putter, for this week at least.

McIlroy lost 1.181 strokes to the field average in his cut-missing effort at the Honda Classic, but it seems that poor performance wasn’t the sole impetus for the change.

Put some good work in the last few days, ready for the blue monster this week!

“Over the past few weeks my right hand was becoming a little bit too dominant, so I practiced over the weekend, just with left below right and it felt really, really good,” McIlroy told reporters at Doral. “I’m going to give it a try this week and see where we go with it. It felt really, 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.”

As you might imagine, McIlroy hasn’t putted well at all on the PGA Tour this season. While he’s only made four starts, the Ulsterman is 189th in Strokes Gained: Putting, losing 0.543 strokes to the field. Worse, he’s 197th in putting inside 10 feet.

McIlroy lost 0.070 strokes to his average competitor last year. In 2014, he finished 41st in SG:P. The best McIlroy has ever placed in SG:P on Tour? 41st.

However, McIlroy isn’t trying a totally unfamiliar technique.

“I used it [the cross-handed grip] back in my first year on Tour, 2008, for a while but it’s a drill that I’ve always done. And I have also putted a lot with just my left hand. It’s one of those things where the drill started to feel better than the real thing so I’m just going to stick with it.”

And if you’re wondering what he’s putting with, here are in-hand photos of McIlroy’s gamer: a Nike Method Origin B201 (prototype).

There will be plenty of eyes evaluating McIlroy’s modified grip: He’s playing with Jordan Spieth and Jason Day for the first two rounds of the WGC-Cadillac Championship.
