Jon Baker began TEG 6 in Catalonia with the best gross round of his career, an 18-over 90 at PGA Catalunya's Tour Course. Almost all of the good work came early, his front and back nines split by 13 shots. He steadied late, playing 14 through 17 without dropping a gross shot, three pars and a birdie at the stroke index 3 seventeenth, and taking six shots off par against his handicap in the process.

The move came in Barcelona. Even after a 9 at El Prat – Rosa's eighth, a quintuple bogey on the second-hardest hole, Baker closed with three straight net gains at 16, 17 and 18 to take the TEG 6 Green Jacket lead from David Mullin, who had held it for 51 holes since the third hole of the tournament. On the seventh green of the final round at the Stadium Course, he did the same to Williams in the TEG 6 Trophy, ending a run of 59 holes in front stretching back to the second hole of the opening round.

He was, at that point, leading both competitions. It is worth pausing on the achievement, because he did not pause on it himself.

Two holes then undid all of it. At the ninth, the hardest on the card, Baker took 10, a sextuple bogey. At the 18th he took 8. Ten shots dropped to par, on the day that mattered, having spent three days assembling something genuinely authoritative.

Henry Meller's trip to Catalonia contained both the best golf of his career and one of its more testing afternoons, 24 hours apart.

The high point came at Costa Brava on the Sunday, where Meller signed for a round of 90. On net terms it was a personal best at -5, and the gross figure of +17 was a personal best too, the first time he had assembled a full round of that quality in TEG competition. He had, briefly, the look of a man who had worked something out.

Round 3 at El Prat's Rosa course took it back with interest. Meller opened with a 10 at the 1st, a par 5 of stroke index 4, a quintuple bogey and the worst hole relative to par he had recorded. There is a certain economy in getting your worst hole out of the way before anyone has settled. It also moved him from fourth to fifth in the TEG 6 Wooden Spoon standings, a position he did not subsequently relinquish, or appear to contest. Seven holes later he ran up a second 10, this time a sextuple bogey at the par-4 8th, the hardest hole on the card. His round came in at 109.

Meller finished the tournament on +30 net against par and collected the Wooden Spoon. The two 10s in Round 3 accounted for seven net shots between them, which was most of the gap he needed to close.

The final round of TEG 6 was played at PGA Catalunya's Stadium Course, the fourth different Catalonian venue in four days and one none of the field had seen before. It took shots off all of them.

Williams received the largest invoice. He dropped 11 shots across the opening four holes, including a 9 at the par-five 3rd, then 13 more from the 6th to the 9th, where quadruple bogeys at the 6th and 7th arrived back to back. The closing five holes cost him another 14, with a 7 at the par-three 16th and a 7 at the last. He signed for 113, his highest round of the tournament by six shots on his own Costa Brava 105.

Stuart Neumann settled up early. A 10 at the par-five 3rd began a four-hole run from the 3rd to the 6th that leaked 12 shots and produced no net par at all. Four straight doubles from the 12th added eight more. That is not a collapse. That is a filing system. He came home in 100.

Jon Baker's round turned on two holes, a 10 at the 9th, stroke index 1, and a quadruple-bogey 8 at the 18th, for a 99. David Mullin fared best of the four with 94, though he gave back seven shots between the 14th and the 16th, including an 8 at the par-five 15th.

David Mullin took the TEG 6 Green Jacket at +85, four clear of Jon Baker, though the gross contest was not the procession the margin suggests. Mullin had led it since the third hole of the opening round at PGA Catalunya's Tour course, and held on for 51 holes across three days.

The lead went at El Prat's Rosa course, a Greg Norman parkland outside Barcelona and one of four Catalan venues making their TEG debut in 2013. Mullin's third round was the worst gross round of his career, +29 for a 101. The damage arrived in two instalments: a nine at the par-four 15th, a quintuple bogey and the worst hole relative to par he has recorded, and another nine at the par-five 18th. He walked off the last with Baker in front of him.

Baker had built his position early, posting a personal-best gross round of +18 on the Tour course in round one. He could not hold it. Mullin's final round at the Stadium course opened badly, a seven at the par-three 5th, four over on its own, which requires a certain commitment on a hole that short. Then he steadied with three straight pars from the 8th, worth three shots to par against his handicap. Baker's quadruple-bogey eight at the Stadium's 18th settled matters, and the Jacket stayed with Mullin.
