Why Pros Are Switching to Sweepers: LAB CEO Sam Hahn Explains

·50 min·3 clips

Lucas Glover's switch led to 2,500 sweepers sold on Monday and about 1,000 a day for 10 days.

1. GolfWell Podcast focuses on LAB CEO Sam Hahn and why Adam Scott and Lucas Glover helped bring sweeper putters into view. 2. Sam Hahn is the CEO of LAB, and the hosts use him to explain the company’s prototype history and tour feedback. 3. The episode asks why more players are switching to sweeper putters, what LAB learned from Adam Scott, and where armlock putting fits. 4. Hahn says Adam Scott first asked for a sweeper in 2019 after using a conventional Directed Force 2.1 for four or five months. 5. He describes the first builds as lead-tape-heavy prototypes because LAB did not yet have bottom weights that made balancing easy. 6. Hahn says the team moved from the DF 2.1 and the blade-one prototype into the B2 and then the B2 bomber. 7. He says the B2 design worked better for sweepers because it was symmetrical, could be scaled up or down, and could use brass. 8. Hahn credits LA Golf and OZIK shafts for changing the category because the older ski-pole shafts were steel and flexible. 9. He says the rigid carbon shafts reduced wobble, improved timing, and made long putters easier for average golfers to tolerate. 10. Hahn says a conventional 350-to-380-gram head at 44 or 47 inches feels too light, while sweepers often need at least 425 grams. 11. He says his own trial with a B2 long and an OZIK 180-gram shaft led to a month of not missing inside 10 feet. 12. Hahn says Craig Winter of the USGA told him he was anchoring because his forearm touched his rib cage below the elbow. 13. He says that rules lesson effectively ended his own sweeping run, even though he still dabbles with it. 14. Hahn says the Mez XL started as a build intended for arm locks and sweepers before Liam Bedford made a conventional-length version. 15. He says Adam Scott later called the raw-aluminum prototype 'the best performing putter I've ever used period.' 16. Hahn says Lucas Glover's agent requested a LAB sweeper, and Glover's wins in 2023 turned the model into a sales surge. 17. Hahn says the company sold about 200 sweepers from January 1 to July 31, 2023, then 2,500 the following Monday and about 1,000 a day for 10 days. 18. Hahn argues that LAB's lie-balanced geometry and low onset help sweepers feel more stable than conventional long putters. 19. The conversation is interview-driven, technical, and practical, with long explanations, rule talk, and equipment comparisons. 20. Listeners who like golf gear, putting mechanics, and tour equipment stories will get the most out of this episode. 21. Listeners who want a short, general golf chat without equipment detail will probably skip it.
