The 2025 Tour Championship has produced low scores the first two days of competition at a rain-softened East Lake Golf Club with Tommy Fleetwood and Russell Henley sharing the 36-hole lead at 13 under par.

Tommy Fleetwood is back for more. His year has been defined by close calls and heartache as the Englishman tries to win for the first time on the PGA Tour.

Five shots back is Scheffler, who is trying to become the first back-to-back winner of the Tour's end-of-season, three-tournament playoff. Scheffler started the day at -7, in second place, finished it at -8 ... in sixth. Here's a look at the biggest questions with 36 holes to play:

BetMGM has Scheffler as +165 to successfully defend his Tour Championship and FedEx Cup titles, which can come as no great shock after he's won five of his last 10 starts. Three-time FedEx Cup champion Rory McIlroy is +800 and Tommy Fleetwood, who has three top-four finishes among his last five starts, is +1200.

Cameron Young keeps making a compelling case for a berth on the U.S. Ryder Cup team. On Friday, his wedges were dialed in, and he birdied five of six holes and half the holes at East Lake Golf Club in Atlanta en route to carding an 8-under 62 in the second round of the Tour Championship.

Shane Lowry was steady without firing on all cylinders in the first round of the Tour Championship at East Lake in Atlanta, the final event of the FedEx Cup playoffs with a $10 million pay-day to the ultimate winner in the limited 30-man field.

Unlike last year, Scottie Scheffler won't start the Tour Championship well under par. But the world No. 1 is still heavily favored in the revamped tournament.
