Jon Baker's final round at Boavista Golf & Spa Resort completed a TEG 3 with the best or tied-best score in every round. His level-net 0 was the best score in the field. The Trophy is his, for the first time.

The round turned through holes 7 to 9, where he picked up four shots against par. The key blow was a net birdie on the par-5 8th, one of the hardest holes on the course, delivered off nothing more exotic than a gross par. He then went through the 8th and the 9th without dropping a gross shot. It was control, applied without ceremony, on an afternoon when three other men were being dismantled by the 17th.

It left Jon Baker as Trophy leader after the round, with David Mullin leading the separate Green Jacket race. Baker's overall Trophy lead grew to 18 shots by the finish. He began the day in front and ended it further in front, which is what four rounds as the field's best or joint-best will do. It was his seventh visit to Boavista. Not a course best for him this TEG. Enough to finish the job.

The 17th at Boavista carries stroke index 17. Officially, it is the easiest test on the course. In round four of TEG 3 it worked its way through the field like a man collecting a debt.

Henry Meller ran up a 12. David Mullin carded a 9. Stuart Neumann arrived last and posted a 10, a sextuple bogey against a par of 4. Three players, one hole, no survivors.

Neumann's was the most costly relative to expectation, six shots added to par on a hole with almost no business allowing it. It stood as his worst score against par of the round. The wider damage of his day was already done by the time he got there, which is its own kind of mercy. None of it changed the shape of the race. Jon Baker stayed clear at the top of the Trophy, Mullin still led the Green Jacket, and Meller remained anchored to the bottom of the Wooden Spoon. The 17th simply took what it was owed from three separate men in one afternoon. That made it the defining scene of the round.

Gregg Williams closed out round four at Boavista with a gross 35-over. It was the worst gross score recorded in the five-man field that day. It was also his third-best net round in seven, which tells you where the pain was living.

The round rested on three quadruple bogeys, spaced out like scheduled maintenance. A 9 at the par-5 3rd. An 8 at the par-4 7th. Another 8 at the par-4 12th. Between the first two, holes 4 to 6 went unexpectedly well. Three straight bogeys, and with strokes received, three shots gained against par. Williams had found the one register in which he was competent, and then left it.

The finish offered nothing. He bled nine shots over the closing four holes. Double bogeys at the 15th, 16th and 18th, with a triple at the 17th sitting in the middle of them. The 15th is Boavista's hardest hole and the 18th one of its toughest, so at least the collapse had taste.
