Those working at the headquarters of Callaway Golf were treated to a nice surprise on Wednesday.

Fresh off his British Open championship, Phil Mickelson stopped by the company’s California office with the Claret Jug and proceeded to let every employee hold it, according to Chad Coleman, Callaway’s head of social media. Mickelson, who used Callaway clubs and balls during his three-stroke win at Muirfield over the weekend, sure knows how to give back to his sponsors.
