Russell Henley has set the pace at the Tour Championship with an outstanding nine-under-par 61 in the first round, establishing a two-stroke lead. The 36-year-old American, already secured in the U.S. Ryder Cup team, showcased his precision with 207 feet of putts, including seven birdies and an eagle, all without a single bogey.

However, Scottie Scheffler, the world number one, is hot on Henley's heels. Scheffler, aiming to become the first player to defend a FedEx Cup title, carded a seven-under-par 63, positioning himself ominously in second place. His birdies on the 15th, 17th, and 18th holes were crucial, with a scrambling par on the 16th proving equally pivotal.

Robert MacIntyre of Scotland and Tommy Fleetwood of England are tied at six under, alongside two-time major winners Collin Morikawa and Justin Thomas, as well as Patrick Cantlay. Rory McIlroy, the world number two, struggled on the back nine, finishing with a 66 after a fortuitous birdie on the 18th.

With 22 of the 30 players under par, the competition remains fierce. The course, affected by recent heavy rain, allowed for preferred lies, enhancing the players' performances. As the tournament progresses, all eyes will be on Henley and Scheffler, with more inclement weather forecasted for Friday, prompting an earlier start for the second round.
