Defending champion Justin Thomas shot an 8-under 64 to grab a share of the first-round lead with Keegan Bradley and Derek Fathauer in the CIMB Classic. Here's how things stand after one round in Kuala Lumpur.
Leaderboard: Keegan Bradley (-8), Derek Fathauer (-8), Justin Thomas (-8), Paul Casey (-7), Anirban Lahiri (-6)
What it means: Thomas shot a record 26 under par in winning this event last year. He's more than a quarter of the way toward that total through one round. Bradley, the 2011 PGA Tour Rookie of the Year, is looking to win for the first time since 2012. Fathauer is looking for his first PGA Tour win period.
Round(s) of the day: Thomas made nine birdies and one bogey. Fathauer was bogey-free, making four birdies on each side. Bradley made six birdies on the front, turned in 30 and eagled the par-5 10th, but had two bogeys and two birdies the rest of the way.
Best of the rest: Paul Casey shot 65, thanks to a birdie-birdie-birdie finish. Counting this round, Casey is 65 under in his last five tournaments.
Biggest disappointment: A 2-over 74 isn't the end of the world, but considering that Emiliano Grillo is coming off a season in which he was rookie of the year, surely he hoped for something better in Malaysia.
Shot of the day: Ernie Els chipped in for birdie on his second hole of the day, No. 11.
Quote of the day: "If there's such a thing as an easy 8-under, it was." - Thomas
Main storylines heading into Round 2: Can Thomas win this event back-to-back, as Ryan Moore did in 2013 and 2014? Can Bradley end his four-year victory drought? Can Fathauer break through for his first win? Can Casey, who has been knocking on the door for several months, finally get a win?
