TGL played for the first time on Monday night instead of Tuesday, and it allowed McIlroy, the No. 3 player in the world, time to get a decent night’s sleep—he lives five minutes from the SoFi Center—and then fly to the west coast for the $20 million signature event.

You can only imagine how the TGL technicians felt when Rory McIlroy walked into his 90-minute practice session last week with two launch monitors from his personal collection. The four-time major champion and TGL co-founder needed to put his concerns to rest before he debuted in the league: Is the simulator used for golf’s new indoor league accurate?

Tiger Woods and Rory McIlroy faced off for the first time in the TGL arena on Monday night. They are co-founders of the league through their venture TMRW Sports and put on a show. It was the league’s most competitive match yet but was not the most watched.
