Woods and McIlory are joined by the likes of Justin Thomas, Collin Morikawa, Xander Schauffele, Tommy Fleetwood Justin Rose as some of the notable names playing in TGL, which is set to expand to seven five-player squads this year, up from six teams of four players.

Ahead of the third season getting underway this winer, Lowry was part of the first swap deal in the league's history, joining McIlory at Boston Common from The Bay Golf Club.

In exchanged, The Bay gain Boston's fourth pick in the upcoming roster formation process (which is similar to a draft), as well as the right to swap one future selection with Boston in the next three offseasons

Alongside this, The Bay also get "commercial considerations" for agreeing to the deal.

"I'm delighted to be joining Boston Common Golf. Having Rory alongside me and being part of this group makes it particularly exciting, and I'm looking forward to helping the team bring a championship to Boston," Lowry said in a statement.

Meanwhile McIlroy added: "Shane is a great friend and someone I love having alongside me in team competition."

"We've had some special wins together, including at the Zurich Classic, and I know the quality of his game and how much he cares about winning for his teammates. I'm delighted to welcome him to Boston Common Golf and excited about what we can achieve together this season."

Last season, Boston Common finished top of the regular-season table, winning four of their five matches, but lost 9–5 to Woods' Jupiter Links in the semi-final.

What is TGL and how is it played?

As it approaches its third season, TGL is set to undergo some big changes, with Motor City Golf Club set to join as the seventh team.

For each match, three players from each team will 15 holes, with the first play nine holes using alternate shots while the final six are singles.

Points are then awarded for winning holes and a closest-to-the-pin shootout deciding tied matches.
