Back To News Stories 12Jun2019 By : Titleist Australia The new Titleist T100, 620 MB and 620 CB irons will make their tour debut at this week's U.S. Open®, marking the first opportunity for players to use the new irons in competition. The three new iron models follow the successful introduction of the new TS2 and TS3 hybrids and U-500 and U-510 utility irons at the recent Memorial Tournament. Validating product performance across the worldwide professional tours is a critical step in the development of all high performance Titleist golf equipment. Based on initial tour player testing and feedback, the new lineup is poised to continue Titleist's run as the most played iron on the PGA TOUR for each of the last five years and 14 of the last 15 seasons. Titleist Tour Representatives and members of the Titleist Golf Club R&D team will be on site at Pebble Beach, fitting players into the three different iron models and gathering additional feedback. Stay tuned to Titleist.com.au and Titleist's social channels for updates as this process continues over the coming weeks across the worldwide professional tours.
