Spotted: PING G400 driver
Bubba Watson is debuting a new big stick at Erin Hills...
Bubba Watson is playing a new driver at the 2017 US Open, believed to be the new PING G400 driver.
The big-hitting PING staffer has his usual pink paint job on show.
Like the impressive PING G driver, which was awarded a gold star in our 2016 drivers test, the new club seems to also have turbulators and Dragon Fly technology, while a new tungsten weight can be seen on the sole.
As soon as we have any information on the new driver, we will let you know!
