Woods still working on $10m Mickelson match

"Phil and I are friends and we are always trying to make each other uncomfortable and needle each other," Woods said of his relationship to longtime rival Mickelson

Tiger Woods said Sunday that he and longtime rival Phil Mickelson are "still working" on a $10 million 'winner-takes-all' match.

"We are still working on it and it's not there yet but we are trying to make it happen," said Woods after playing several practice holes at the Carnoustie course in Scotland, where this year's British Open starts on Thursday.

"Phil and I are friends and we are always trying to make each other uncomfortable and needle each other," Woods added.

Between them, the two Americans have won 19 major championships, although Woods has 14 to Mickelson's five.

The pair's hauls include both British Open and US Masters titles.

Patrick Reed, this year's Masters champion, recently joked he would only watch Woods tackle Mickelson if they each put up their own money.

When this point was put to him on Sunday, a laughing Woods replied: "Of course, that is what Patrick would like to see and it would be good of him to put up that money."
