We’re debuting a new weekly feature here at GolfWRX called Numbers of Interest, with potentially overlooked items from the winning golfer’s performance, focusing on the final round. We conceive of this feature as being stats and detail heavy, which was made difficult this week by poverty of ShotLink data and the match play format. Nevertheless, here are some significant numbers and details of interest from Jason Day’s triumph.

Day’s 5&4 victory over Louis Oosthuizen in the WGC-Dell Match Play championship match is the largest margin since Tiger Woods defeated Stewart Cink 8&7 in 2008. (And that was a 36-hole match).

Perhaps the most impressive element from the win isn’t a number, detail, or the margin of victory, but the fact that Day suffered back spasms in his opening match against Graeme McDowell that were so bad he nearly had to withdraw. And it wasn’t like (no pun intended) the issues were behind him as the week progressed.

Here’s what Day said about the back following his win.

“A lot of people don’t realize that I’m — I get here two or three hours before my tee time, try and get therapy and I’m there like another hour after my rounds trying to get therapy and I’m in between rounds trying to get therapy.”

Day added that Bubba Watson’s therapist, Brian Smith, played a key role, as his is presently in South Africa.

“Our whole team, James Bradley, who is our doc on our team…and then Cornell Driessen, who is my trainer, they’ve all been in communication throughout the whole week, making sure we’re taking the right steps towards getting me back and playing.”

Regarding Day’s championship match win: From No. 4 to No. 14, where the match ended 5&4, Jason Day missed just one green in regulation.

Much attention will be given to combination of power and precision Day showcased at Austin Country Club’s 509-yard, par-4 14th hole to close out the match, and rightfully so. Day stepped up and ripped his drive 352 yards to the left side of the fairway, using his TaylorMade M1 460 (10.5 degrees, adjusted to 9.5 degrees) with a Mitsubishi Rayon KuroKage S TiNi 70X (tipped 1 inch).

Day then nipped a 109-yard approach shot with one of his TaylorMade Tour Preferred EF wedges to 2 feet, 9 inches and tapped in his TaylorMade Tour Preferred X golf ball (No. 87) to wrap up his second WGC-Dell Match Play Championship in the past three years.

But beyond the pin-seeking approach at the 14th, Day was firing darts across much of the aforementioned 12-hole stretch.

Have a look.

• No. 4: Jason Day: Shot 1 187 yds to green, 11 ft 2 in. to hole
• No. 5: Jason Day: Shot 2 130 yds to green, 2 ft 6 in. to hole
• No. 9: Jason Day: Shot 2 100 yds to green, 6 ft 10 in. to hole

The effort at No. 9 was particularly ridiculous when compared to his playing partner.

The details, via the PGA Tour’s ShotLink:

• Louis Oosthuizen: Shot 1 271 yds to right fairway, 187 yds to hole
• Jason Day: Shot 1 353 yds to right fairway, 99 yds to hole
  
• Louis Oosthuizen: Shot 2 191 yds to right green side bunker, 81 ft 1 in. to hole
• Jason Day: Shot 2 100 yds to green, 6 ft 10 in. to hole

Tough to compete with that. 

Also notable: At the 317-yard par-four 13th hole, Day went for the green with his tee shot, winding up just off the green and just over 70 feet from the flag, en route to a hole-winning birdie.

After winning all seven of his matches this week, Jason Day’s WGC-Dell Match Play record is 21-6 and his winning percentage is a superb 78 percent. The 21 victories put him sixth on the list of players with the most Match Play matches won behind Tiger Woods (33), David Toms (24), Ian Poulter (23), Stewart Cink (22), and Rory McIlroy (22)

His last 13 worldwide starts haven’t been too bad, per ESPN’s Jason Sobel.

Oh, and a final number: Day pocketed $1.62 million for his winning effort.
