After a day of difficult scoring at East Lake, a pair of familiar names are near the top of the leaderboard. Here's how things stand after the first round of the Tour Championship, where Dustin Johnson shares the lead in search of his second straight win:
Leaderboard: Hideki Matsuyama (-4), Kevin Chappell (-4), Dustin Johnson (-4), Jason Day (-3), Si Woo Kim (-3), Jordan Spieth (-2), Rory McIlroy (-2)
What it means: Birdies were hard to come by for the 30-man field in the early going, but eventually some of the top players in the world got it into red figures.
