The same guy who is leading the FedEx Cup race is also on top of the leaderboard after two rounds at the Tour Championship. Here's the lowdown heading into the weekend at East Lake:
What it means: Johnson and Chappell have separated themselves a bit from the field as DJ looks to follow up his win two weeks ago at the BMW with a win at East Lake. Johnson just needs to finish in the top 5 to win the FedEx Cup and the $10 million bonus, but he will no doubt be focused on winning his fourth title of the season.
Round of the day: Russell Knox may not be heading to Hazeltine next week, but he's right in the mix for a solid finish to his career season after a 4-under 66. He recorded a birdie and a bogey on the front nine, and then Knox came home with four birdies to finish at 1 under, six shots off the lead.
Best of the rest: Johnson was heading for at least a 66 of his own, but he stumbled coming in. He made two birdies on the front and two more on 10 and 11 to reach 8 under par. Johnson hit a wayward drive on 17 that led to a bogey, and he didn’t take advantage of the par-5 18th. Still, a 3-under 67 gave him the lead after two rounds.
Biggest disappointment: He came into the week "cautiously optimistic" about his ailing back, but world No. 1 Jason Day didn't even make it through two rounds. Day hit his tee shot into the water on the par-4 8th hole, and then he hit another driver for his third shot out of the rough. Day released a statement that read "He withdrew as a precautionary measure. Jason should be fine with some rest after a long break in the offseason.”
Main storyline heading into Saturday: Will anyone challenge Johnson and Chappell over the weekend? Chappell has yet to win on Tour, so Johnson clearly has the advantage against his playing partner. But Casey (No. 5 in FedEx standings) and McIlroy (No. 6) have been solid in the playoffs and have a chance at the $10 million if Johnson falters.
Shot of the day: McIlroy went flag hunting with his second shot at No. 12:
Quote of the day: "That’s been the biggest thing is just putting in the work.” – Johnson
