The PGA Tour has won their first legal battle against the controversial LIV Golf brand, with a judge ruling on Tuesday that LIV Golf players are not eligible to play in the FedEx Cup starting this week.

Specifically, Talor Gooch, Matt Jones and Hudson Swafford were the three golfers seeking the temporary restraining order to play at the FedEx St. Jude Championship – but a judge ruled that their cases did not prove they were victims of "irreparable harm" due to their highly paid contracts.

The LIV Golf lawyers argued that the FedEx Cup is about "more than money" – even going as far as calling it "the Super Bowl of golf", and comparing former FedEx Cup winners to all-time greats Jack Nicklaus and Greg Norman.

They claimed the PGA Tour was attempting to use monopoly powers to stamp out fair competition, to which the PGA lawyers countered with the facts that five of their top-10 most famous players – based on their Player Impact Program – have already jumped ship, and that Gooch, specifically, signed a contract worth significantly more than the $18million awarded to the winner of the FedEx Cup.

LIV Golf were queried about how they could project a 20 per cent market share while also calling the PGA Tour a monopoly, and that being a monopoly is not illegal, only using monopoly powers against another organisation is.

The judge explained that the breakaway golfers would have ample opportunity to play on the alternate tour; that their upfront LIV Golf contracts took into account the possibility that they would not be eligible for the FedEx Cup and/or major championships; and that the inability to win even more money does not constitute "irreparable harm".

Some other interesting tidbits were revealed during proceedings, including a direct contradiction from a prevalent storyline about the LIV Golf contracts.

LIV Golf lawyers claimed that prize money won from tournaments would be "recouped against the LIV contracts" – with a clip emerging immediately afterwards showing an LIV Golf spokesperson specifically saying during a news conference featuring Pat Perez and Brooks Koepka that all prize money would be "in addition to the contracts".

Their lawyers also confirmed that all 48 spots had been filled for next LIV Golf season, and the judge indicated that the larger-scale antitrust trial would be tentatively scheduled for September.

Matt Jones eased to victory at The Honda Classic by five strokes for his first PGA Tour title in seven years.

Not since the 2014 Houston Open had Jones won on the PGA Tour, but the unheralded Australian golfer ended his agonising drought on Sunday.

Jones carded a final-round 68 to reach 12 under overall and tie the largest margin of victory at The Honda Classic in Palm Beach Gardens, Florida.

The 40-year-old mixed five birdies with three bogeys as he claimed his second Tour title after taming PGA National, while booking a spot at next month's Masters.

"I've had some tough times between that and now," a tearful Jones said after finishing ahead of Brandon Hagy. "It's pretty emotional… seven years.

"I just worked hard, working out with my coach back in Australia and it's paid off.

"It was probably the calmest I've been at a golf tournament for four straight days. You can't get a tougher golf course to win on than this one, in these conditions.

"To be able to do that is something that I can build on for the rest of the year hopefully."

Hagy's runner-up finish capped a memorable week for the 30-year-old California native, who closed out the tournament with a four-under-par 66.

The American entered the field on Wednesday as second-to-last alternate when Kramer Hickok withdrew and then shot a career-low 62 on Friday.

Hagy secured his first top-two finish and second career top-10 performance in his 81st start on Tour.

Chase Seiffert (64), Brendan Steele (65), Denny McCarthy (67), Russell Henley (68) and C.T. Pan were tied for third, six shots adrift of Jones.

Defending champion Im Sung-jae posted a 70 in the final round to finish seven strokes off the pace.
