Rory McIlroy played 18 holes at Muirfield yesterday while in possession of his latest Nike driver.
He remained in Europe to test new equipment after missing the cut at the Irish Open.
“I went over to London after Ireland, tried a few drivers with different settings and as soon I hit it I said this is the one,” McIlroy said. “It feels great.”
Meawhile Tiger Woods may insist his injured left elbow should not cause him any trouble during the Open but the world number one was restricted to nine holes of a practice round yesterday.
