According to Bryson he got a new shaft
DeChambeau sent a member of his team to grab a replacement shaft from his car while he continued to play the seventh hole and had it replaced before he reached the par-3 8th hole.
“The head is fine, it’s just the shaft. That was weird, swinging too hard. I guess it’s all those swings I put in. Glad I can replace it, that’s awesome. That’s a nice break,” DeChambeau said on course.
“I think it is so funny. It was bound to break. I’ve been using it for a long time. Got a lot of good use out of it.”
In fact afterwards DeChambeau said the shaft had lasted over a year and had been put through its paces a significant amount.
“This material isn't going to last forever, no matter how strong you make it, but that thing has lasted over a year swinging it over 200-mile-an-hour ball speeds. I'd say it's done pretty dang well and to be able to put another shaft right back in and have that thing perform amazing, it just shows how amazing that company is,” DeChambeau said of the Cobra SpeedZone driver.
On his first swing on the long par-4 ninth with the new shaft DeChambeau pounded his tee shot 327-yards into the fairway and would walk off the hole with a birdie to turn at three under, just two shots off the lead.
“The nice part about it is that I've used that shaft on the practice range this week, testing, just making sure I have backup shafts. I pretty much do that every week for the most part because I know I'm swinging it this fast, something is going to happen sometime,” DeChambeau added.
