What's it really like to caddy for DeChambeau?

Nine months ago they were slowly taking Winged Foot to pieces as Bryson DeChambeau captured the US Open by six shots, now they are no longer an item. There might not be a more fascinating (and exhausting) bag to be on in the game and Tim Tucker was by the American's side for all of his eight wins before they parted company on the eve of DeChambeau's defence of the Rocket Mortgage Classic.

“I made a big mistake with my timing with it, it shouldn’t have happened that way, we should have finished out the week,” Tucker explained on Golf's Subpar podcast. “I didn’t mean to put that pressure on him, I’m sure he had a lot of pressure that week to play in the Rocket Mortgage. I regret how that all went down. I wouldn’t say [it was my decision], it was a combination. The thing I’ll say is that I have been very fortunate to caddy for this guy. He is one of the hardest workers I’ve ever seen and sacrifices everything for this game.”

DeChambeau, who would miss the cut, had Cobra's Ben Schomin on the bag – Schomin would later put DeChambeau in his place after his Open outburst on the nature of his driver. He now has Brian Zeigler by his side.

Tucker then revealed the lengths to which he would go in his work with DeChambeau, some of which are extraordinary.

He would have to factor in air and green density numbers, dropping balls on the greens before doing the same on the practice putting green to establish a base and then go from there, monitoring how changes in conditions might affect things.

“That is one of the most important things we’ve done – green density. Understanding I’m hitting a 7-iron with 6200 (rpm) spin landing into a 2% slope, it’s going to run out four yards on a 6mm green density. That’s important and it’s predictable.”

There was also mention of how he handed the putter to DeChambeau and his freezing and heating up of balls to see how the spin rates were affected.

“Bryson is very demanding. I think that’s a great attribute from an employer because it makes you get better. If you’re not getting better and learning and pushing everything you’re doing, then you become complacent and start making mistakes and you’re not continuing to grow. He makes you do that, and it’s unbelievable. He demands it from everybody. Bryson knows all the answers – I just walk him through the steps. He’s got so much going on in his brain. I’m not telling him what to do. We’re just presenting the problem and solving the problem, that’s all.”
