Adam Scott was recently spotted using an AutoFlex SF505XX shaft in his Titleist TSi4 driver at this years Farmers Insurance Open at Torrey Pines. The sight of both this new shaft, and a first glimpse of the TSi4 has started the rumor mill running about when we can expect to see the new additions to the Titleist TSi driver lineup.

Whilst the AutoFlex shaft is unlikely to be a stock option its interesting to see Scott putting this in play. AutoFlex stated that they constantly look to “challenge the conventional wisdom of golf” and have produced shafts that are incredibly light and flexible. It’s be reported that Scott has been testing the shaft options since as far back as last years Masters.


After the huge success of the TSi2 and TSi3 driver release people are already looking towards when the Titleist TSi1 and TSi4 drivers will accompany them. Originally the TS2 and TS3 drivers were released on the 28 September 2018, this was followed by the TS1 and TS4 that came on the 27 June 2019. With the TSi2 and TSi3 drivers their release came slightly later than September, appearing to the general public on 12 November 2020. However it’s likely this time around TSi4 will be release first, with TSi1 following after that. It could be that we see TSi4 as early as February or March 2021, with TSi1 following in the Spring.
Titleist originally added the TS1 and TS4 to the TS driver lineup in order to provide for Golfers that were topping out at the extremes of the fitting zones. They were designed to cater towards Golfers looking for more, or less launch and spin. Whilst the TS1 looked to provide a high launch with mid spin levels, packaged in a traditional 460cc head, the TS4 was the smallest head size offer at 430cc with mid launch and low spin characteristics. What we will all be watching for is if Titleist have been able to uprate the TSi4 to a 460cc head size whilst maintaining the original aim of delivering towards the the high-spin player looking to reduce spin.
Whilst the Titleist TSi4 has been spotted on the USGA conforming list there is no sign yet of the Titleist TSi1 which is due to it not currently being in play on Tour.

As soon as a release date is announced for both drivers will bring you the latest information. We’ll also be keeping an eye on the conforming lists for the appearance of the TSi1 driver.
