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.

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?

Turns out that having Tiger Woods and Rory McIlroy on your broadcast does good things for TV ratings. Who knew? TGL's fourth week featured a series of firsts for the new tech-infused indoor golf league: both Woods and McIlroy head-to-head in a competitive match.
