Rory McIlroy will likely put the TaylorMade Spider Tour Red putter in play for the first time at this week's US Open at Erin Hills.
McIlroy, who has been out of action the past month with a recurrence of his rib injury from earlier this year, has been getting to work on the greens during his break leading up to the second major of the season.
The Northern Irishman currently uses 13 TaylorMade clubs, but according to TaylorMade's Vice President of Tour operations Keith Sbarbaro, that could be about to extend to 14 with the introduction of the Spider Tour Red putter, as also used by Jason Day (red) and Dustin Johnson (all black version).
"He tested it on all the monitors and it just outperformed everything," Sbarbaro told the PGA Tour.
"Perfect speed, launch and spin with almost no sidespin. The (TP Collection) Mullen and the Odyssey (O-Works) were giving him more sidespin if he didn't hit it perfect."
The slight differences to the original Spider Tour Red version include a single black line on the crown to aid better alignment, and a "Rors" stamp on the sole.
EQUIPMENT: TAYLORMADE SPIDER TOUR RED PUTTER
McIlroy told the PGA Tour: "That's one of the reasons I went to the mallet — I sort of figured it helped me align better and helped with my aim.
"It's awesome with the Spider because you set this thing up and you know exactly where you're aiming, and it sits so square with that with that flow neck."
McIlroy had been previously using a Scotty Cameron Concept M1 putter, before moving over to an Odyssey O-Works prototype.
Should McIlroy make the change official at Erin Hills, it would mark the first time that the world's top three players - Johnson, McIlroy and Day - all use a TaylorMade Spider Tour putter.
