GOLF: You might think it's all over, but we're not too sure. Neither is Roger Mullarkey, our leader going into the final week of the 2002 Golf Masters, nor Pat Callanan, his closest rival. True, Roger extended his lead over Pat to almost €74,000 at the weekend, but, he points out, with some trepidation, there is a man who has it in his power to scuttle his Golf Masters-winning hopes and dreams: Padraig Harrington.

"If Harrington wins in Mount Juliet I'm blown out of the water," Roger admitted. "If Harrington wins in Mount Juliet Roger could end up with nothing," added Pat, aware of that old Golf Masters' rule: "an Irish player winning any of the events staged in Ireland shall receive €400,000". Pat has Harrington in his second-placed team, Roger doesn't.

In all, four of our top 10 managers have Harrington in their line-ups going into the American Express World Championships, a bonus tournament offering one-and-a-half times the regular prize money: Pat, third-placed Vincent Maloney, Brendan Hill in fifth and Pat Corby in ninth.

None of the top 10 has the second Irish player in the Mount Juliet field, Darren Clarke, in their teams, but the man in 19th place will use his final transfer to bring Clarke in for the last hurrah. And that man is? Pat Callanan.

"There's no doubt, if Darren Clarke won at the weekend it would turn it all upside down," said Pat, "you'd probably have three unheard of teams coming from nowhere. If either Clarke or Harrington won I'd be in with a shout, but I'd still prefer to be in Roger's position, €74,000 ahead."

So, how are you Pat? "Not too bad," he said, "but I was better two weeks ago." Back then, of course, Pat was sitting pretty at the top of the leaderboard, where he'd been for eight uninterrupted weeks, but then Roger's Razor Sharp found a bit of form.

Now Pat's doing the chasing and, barring Clarke triumphing at Mount Juliet and catapulting his 19th placed team into reckoning, he is dependent on Harrington, Vijay Singh and Eduardo Romero winning €74,000 more than Justin Leonard, Robert Allenby and Thomas Bjorn, Roger's representatives this week (like the rest of the top 10, both managers employ Fred Funk, so his form this week is largely irrelevant).

Roger, how are the nerves? "Not too good. Harrington's the big worry. I know he's had his injury problems but you just don't know what he's capable of this week. Bar him winning it I should be okay, but I'm not counting any chickens - he if does win it I'm finished. And then there's Darren Clarke - if he wins €400,000 then the current top three could disappear."

Pat is hoping to get down to Mount Juliet on Sunday, where he can remind Harrington and Clarke, in person, just what's at stake here. Roger is planning on watching the All-Ireland final on Sunday, but suspects he may miss the bulk of it, too busy keeping an eye on events in Kilkenny. Good luck to all: ye're in for a hell of a week.

We have a tie at the top of our weekly leaderboard but know the name of only one of the managers, Ciaran McCallion. The other manager has until tomorrow (5.0) to declare himself (ring 01-2844060), providing his or her pin number for proof of identity. At that point we will set a Ryder Cup-related tie-breaker for the managers. If we don't hear from "No Name Given" by then the weekly prize will go to Ciarán.
