Reigning Open champion Zach Johnson has signed a new endorsement contract with Parsons Extreme Golf (PXG) -- which started doing business just last spring.

The new company was started by GoDaddy.com founder Bob Parsons, who also signed 2014 FedEx Cup champion Billy Horschel, James Hahn, Charles Howell III and Chris Kirk. Ryan Moore had previously been on the playing staff. Champions Tour player Rocco Mediate also endorses PXG.

Brooks Koepka, who won the Waste Management Phoenix Open, and promising 2015 rookie Tony Finau joined the Nike staff that is led by Tiger Woods and Rory McIlroy.

Cristie Kerr is among the LPGA players who have signed with PXG, which last year began marketing an expensive line of clubs that includes a $700 driver and irons that cost $300 each. A set goes for about $5,000. Other LPGA players with the company are Alison Lee, Gerina Piller and Beatriz Recari.

Parsons has been said to give his designers an unlimited budget to build the best clubs possible.

"One thing you'll see on our clubs that you won't see on any others is a warning: Our clubs are amazing but expensive," Parsons told Golf.com. "The guys we sell to mostly belong to private clubs, they're businessmen, they're a little bit older, and anything they can do to help their game, they'll do it. Often, the guys we sell to don't even ask what they cost."
