Justin Rose isn't the only big-name pro golfer signing with Honma Golf; we know this for certain.
Paul Casey may well be one of those top-tier players to have already signed with the Japanese equipment maker.
Casey was spotted at the 2019 Sentry Tournament of Champions playing Honma equipment ahead of the year-opening event at Kapalua Resort's Plantation Course on Maui in Hawaii. Golf.com reported on the sighting based on photography from the event, specifically calling out Casey using a TW-U Forged utility iron.
The Englishman, who got into the Tournament of Champions on the back of his March win in the Tampa area at the Valspar Championship, had been using TaylorMade metalwoods and Mizuno irons.
What we don't know is if Casey has signed a deal with Honma to play their clubs, and if he has, what the structure of that deal looks like. He could be choosing to play bits and pieces of Honma Golf equipment without a contract, akin to what he's done since Nike Golf left the hard goods (club-making) portion of the business in 2016.
Over the next week, we'll have a better clue on who's signed where and for which pieces of equipment. Honma Golf, however, is looking to use capital investment further backing the company to help finance bringing on as many as four pros to establish its PGA Tour staff. If Rose is one, and Casey might be another, then who's left?
