Chad Campbell

The 34-year-old Texan made his debut on the losing US side at Oakland Hills in 2004, where he lost twice in the fourballs, but defeated England's Luke Donald in the Sunday singles.

Two years' later he achieved a notable half against the feared Ryder Cup pairing of Colin Montgomerie and Lee Westwood, partnered by Vaughan Taylor, but this time fell to Donald in the singles as Europe once again prevailed.

Campbell is a big-hitter, who Azinger believes can take advantage of the open Valhalla layout and bring a calm consistency to proceedings.

His selection alongside Steve Stricker, JB Holmes and Hunter Mahan was seen as the biggest surprise of the four wildcards, however, and Campbell will feel he has a point to prove when the action gets under way.

"I picked three guys that had never played Ryder Cup before and I thought Chad had experience and played well this week. I knew he was the right guy," Azinger said.
