MELBOURNE, Australia (AP) - Tiger Woods and Steve Stricker might not be playing together in every match at the Presidents Cup.

Woods and Stricker became the first partnership in 30 years to win all four matches in any cup competition two years ago in the Presidents Cup. They lost only one out of three matches last October in the Ryder Cup.

Woods says Stricker appears to be hitting the ball as well as ever. But he says the pairings are not set in stone. One possibility is for Woods to play with Dustin Johnson in the fourballs competition.

Johnson and Phil Mickelson, close friends who play against each other in practice rounds on the PGA Tour, did not pan out well at the Ryder Cup. Johnson says he and Mickelson play better when they compete against each other.
