Winner's Bag: Jordan Spieth, U.S. Open

Jordan Spieth fired a final-round 69 to win the U.S. Open by one shot over Dustin Johnson and Louis Oosthuizen for his second straight major title. The 21-year-old made one change to his bag setup for Chambers Bay, replacing his 20.5-degree Titleist 915H.d hybrid with a Titleist 712U utility iron (3-iron) to account for the firm course conditions. 

"Sometimes I'll switch between a driving 3-iron or a hybrid," Spieth said. "If it's firm and windy, driving 3-iron is perfect for me."

While Spieth used the utility iron to hit a number of key shots, it was his 15-degree Titleist 915F fairway wood that helped pull off the shot of the tournament. 

Following a double bogey on the 17th hole, Spieth found the fairway with his drive on the par-5 18th and took dead aim from 285 yards with the fairway wood, watching as his ball settled within 15 feet of the hole for eagle. 

"I said, ‘Put it in the fairway; give yourself a chance,’" Spieth said. "It got right up there on the upslope; I couldn't have placed it in a better spot. The next 3-wood … very, very pure. Any little bit of breeze up there held it up. For how undeserving maybe after I played 17, that break was on 18, for it to funnel down and then to stay up by a foot on that ledge … I just wanted to get a good putt."

Spieth put the 3-wood in play last August, a few weeks after Titleist introduced it to staff players. The re-designed 915F fairway wood (175cc) features an Active Recoil Channel (ARC) in the sole that runs from the heel to the toe — closer to the leading edge — that increases ball speeds while also reducing spin. 

To increase ball speed even further, Titleist added a Carpenter 455 face insert — the thinnest the company has used for a fairway wood. The 915F creates slightly more spin and a higher launch angle than the more workable 160cc 915F.d.

Here's a look at the rest of the equipment in Spieth's bag.
