Phil Mickelson has been dropped from Saturday's morning fourballs by US captain Hal Sutton, presumably as a result of failing to win a point in his first two matches. His playing partner for those matches, Tiger Woods, will partner Chris Riley in the second match against Darren Clarke and Milton Keynes' very own Ian Poulter.
Bernhard Langer, on the other hand, is ensuring that his remaining rookies, David Howell, Ian Poulter and Paul Casey all play their first matches, while retaining the successful pairings of Garcia/Westwood and Monty/Harrington. Montgomerie will maintain his record of playing in every series since Kiawah Island in 1991, a span of 30 (and counting) consecutive Ryder Cup matches.
Giving rookies their first game in fourballs, as opposed to foursomes, is a shrewd move. It gives them a chance play their way into a match, without the pressure of knowing that every stroke they play is crucial. It also gives them marginally more Ryder Cup experience; they'll hit 60-70 shots in fourballs, and roughly half that in foursomes. Those extra few shots may count for a lot come Sunday.
