Brooks Koepka took a subtle dig at rival Bryson DeChambeau on Twitter on Thursday shortly after news broke that he would be without longtime caddie Tim Tucker as DeChambeau looks to defend his title at the Rocket Mortgage Classic this week. Koepka declared it "caddie appreciation day" and shared a post thanking his current caddie, Ricky Elliott. "Couldn't do it without my guy Rick! Best friend and greatest caddie to do it @RickyElliott appreciation day!" Koepka's declaration of appreciation for his caddie came on the same day DeChambeau's caddie called it quits.
