Ryder Cup Foursomes Draw:Three-time major winner Padraig Harrington will be in the top match alongside Sweden's Robert Karlsson when the European team get their Ryder Cup campaign underway at Valhalla tomorrow morning.
Harrington and Karlsson will take on the American pairing of Phil Mickelson and Anthony Kim in the first match of the weekend as the visitors start their bid for an unprecedented fourth consecutive title.
As to who hits the first shot, Harrington and his partner have yet to decide with the Dubliner commenting: "We have got to do a little bit of thinking on that. Think about it and see what we are comfortable with. The course seems to set up where it is not obvious to go one way or the other.
"Robert has been playing great all year and he is certainly somebody I looked to play with and he looked to play with me. While you can't make too much of a deal out of the first session, momentum is always nice to have on your side."
Next out will be Henrik Stenson and Paul Casey, who face Justin Leonard and Hunter Mahon, before the all-English pairing of Justin Rose and Ian Poulter tackle Stewart Cink and Chad Campbell.
The final match of the morning foursomes sees the vastly experienced team of Sergio Garcia and Lee Westwood take on the veteran American Jim Furyk and his partner Kenny Perry.
The European pairings are exactly the same as those that team captain Nick Faldo had unwittingly allowed to be caught on camera yesterday.
Only the order of those involved was different, with Poulter and Rose elevated up the order while Graeme McDowell and Miguel Angel Jimenez will now not see any action until the afternoon fourballs at the earliest.
Faldo had tried to laugh off his slip-up yesterday, suggesting the sheet featuring the pairings was the players' "sandwich list" before having to confess that he had been caught out.
It gave opposite number Paul Azinger a heads-up on what Faldo's thinking was before the handing in of their line-ups at lunchtime in Louisville today.
Many thought Faldo would start with Garcia and Westwood, but he said: "It's pretty tough to push a three-time major champion out of his seat."
America have not won the opening session since Kiawah Island in 1991 and the last time they even shared it was 11 years ago at Valderrama. In the last three matches fourballs have come first. Azinger, as the home captain, has changed that in the hope of improving matters.
Garcia and Westwood, though, bring with them two formidable records — both together and separately. As a partnership in 2002 and 2004 they have played six, won four, halved one and have lost only to Woods and Davis Love in fourballs.
Garcia has a perfect eight victories from his eight foursomes, while, equally incredibly, Westwood has won his last 10 games — only two short of Arnold Palmer's record unbeaten run in the event.
