Equipment Roundup: BMW Championship

Xander Schauffele made a putter change at the Dell Technologies Championship, swapping his Odyssey Works Big-T #5 mallet for the putter manufacturer's O-Works Red #7CH (34.5 inches). The two-time TOUR winner noticed an immediate improvement in his aiming but felt the ball was coming off the Microhinge insert with too much speed.

Working with Callaway Tour rep Johnny Thompson at the BMW Championship, Schauffele went to a version of the putter with a slight counterbalance in the grip. Thompson removed 10 grams of weight from the head and repositioned it in the butt end of the SuperStroke Pistol GTR 1.0 grip.

The weight shift essentially helped Schauffele take out some energy at impact and dial in his speed control.

While the change was slight, it proved to be a game-changer for Schauffele, who finished the week second in Strokes Gained: Putting en route to a third-place finish that booked his spot at East Lake Golf Club for The TOUR Championship.

Day's driver shaft: Jason Day became the third player on TOUR (joining Pat Perez and Martin Kaymer) to put Accra's 70-gram prototype driver shaft in play at Aronimink Golf Club. The Aussie, who opened 2018 with a TPT shaft in his TaylorMade M3 driver at the Farmer Insurance Open, tested the prototype on Tuesday and saw ball speeds of 181 miles per hour with a launch of 13 degrees and 315 yards of carry (345 yards total).

While the numbers were close to what he was seeing from the TPT shaft, the difference for Day was in the dispersion department, where he noticed a tighter pattern, which led to the change.

Bradley, who spent his collegiate career playing for the Red Storm, asked Odyssey reps if they could create a one-off Works 1W Armlock with the same red paint scheme.

"I know the release point and I know how it swings and my body morphed into a position where it understands where it needs to be to release the putter," Woods said.

"I've hit hundreds of millions of putts. I've had it since '99. I've hit putts with it. I just — my body just remembers it. When I go away from it — and, you know, when I was using the Nike putter I always bring it out and hit putts with it. Sometimes it works but it just feels very familiar to me."

Woods opened with 62 but struggled to replicate the performance over the next three days. He lost more than three-and-a-half strokes to the field with the putter during the second round before closing with two positive Strokes Gained: Putting rounds.
