Woods earned medalist honors as he fired a 7-under-par 65. That earned him $200,000.
'I'm playing better,' acknowledged Woods. 'It's a good sign. Hopefully, I have a good practice session this week and head up to Augusta.'
Each golfer played two singles matches. A win was worth one point, a tie 1/2 point and a loss zero points. There were 20 points available on Tuesday and once Isleworth reached 15 1/2 points, they won the Tavistock Cup.
Woods was paired with John Cook on Tuesday and they faced Lake Nona's captain Ernie Els and 52-year-old Champions Tour star, Mark McNulty.
Woods made some pars out of the gate on Tuesday, but rolled in a 25-foot birdie putt at the fifth. He added a short birdie putt at six, then birdied the seventh to make the turn at 3-under par.
At the 10th hole, Woods hit a long drive, then pitched 10 feet short of the flag. He ran home the birdie putt, then added another birdie at the 14th when his 20-footer found the bottom of the cup.
He closed with a 10-foot birdie putt at the last for his 65.
That gave him victories over both Els and McNulty. Els shot an even-par 72 and McNulty was the surprise of Tuesday with a 4-under-par 68. They both lost to Woods, but beat Cook, who only shot a 76.
'It was one of those deals,' admitted Els. 'Today wasn't a great day. It was great seeing Tiger play. He was hitting it so good. And so was the old man.'
Isleworth's captain struggled mightily in the opening match. Mark O'Meara shot an 8-over 80 and lost both matches to Lake Nona's Trevor Immelman and Maarten Lafeber. O'Meara's partner Arjun Atwal went 1-1 after he shot an even- par 72 to lose to Immelman's 68, but trump Lafeber's 74.
Match two saw Isleworth sweep all four points in a somewhat shocking manner. Charles Howell III fired a 4-under 68 and Stuart Appleby managed an even-par 72. They upstaged the higher-ranked duo from Lake Nona as the feature a pair of top-10 players. Retief Goosen carded a 1-over 73 and Sergio Garcia only posted a 2-over 74.
Robert Allenby of Isleworth fired a 4-under 68 to topple both Justin Rose and Ian Poulter of Lake Nona. Rose fashioned a round of 1-under 71 and Poulter was one stroke higher. Craig Parry of Isleworth also shot a 72 to lose to Rose and halve with Poulter.
Robert Damron of the Isleworth team was the low man in the fourth match. His 1-under 71 was good enough to knock off both 2003 British Open champion Ben Curtis and Graeme McDowell. Curtis (73) and McDowell (74) both earned victories over Lee Janzen, who struggled to a 3-over 75.
This was Isleworth's second victory in three tries. Last year, the teams tied as darkness forced the stoppage of a playoff. The Isleworth squad each pocketed $100,000 for the win.
