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?

Between personal observation and some internet rumblings about the quality of the technology employed by the new tech-driven indoor golf league he co-founded with Tiger Woods, Rory McIlroy decided recently to put TGL’s simulator through his own test.

McIlroy said Woods was as intense as ever for their Week 4 match, the first close one so far in the indoor sim league.
