Wildcard Scott Verplank said he had asked United States captain Tom Lehman to play him in the afternoon foursomes on Saturday but finished up sitting out another session.
Unlike fellow wild-card Stewart Cink, who will now play five matches out of five, Verplank has had only one run out, a 2 and 1 Saturday morning fourball success over Padraig Harrington and Henrik Stenson in which partner Zach Johnson closed the match down on the 17th by chipping in.
Lehman decided to put out Johnson in the afternoon instead of Verplank, who admitted his young partner had been the dominant member of the team.
A clearly emotional Verplank said his omission was a blow, telling a news conference: "I didn't know (about Lehman's decision). If he was choosing between me and Zach, Zach played good, but I didn't know it was coming down to that.
"I'm sitting in here but I sat in here all yesterday, too. I did win one point today, the only chance I got.
"I would be lying to you if I told you I wasn't disappointed and feel like I should have another chance or two. But I'll have another chance tomorrow and hope we still have a chance as a group to win.
"If we win this, captain Lehman is going to look pretty much like a genius and that's what I'm hoping.
"He came up at 13 and told Zach he was playing with so-and-so and I said: 'Well am I playing this afternoon?' and he said: 'No.'
"I said: 'We're going to win our match, I'd like to play, but he already had it set."
Johnson was paired with Verplank's fellow wild-card Cink in the second day foursomes.
Lehman, who described Verplank as the perfect player for the K Club when he selected him last month, also held back rookie Vaughan Taylor, giving him his first outing in Saturday afternoon's foursomes.
In stark contrast European captain Ian Woosnam used all 12 of his players on both days - with all of them contributing to the points tally.
