He's not the highest-ranked player in this week's field, but Phil Mickelson will likely draw the biggest crowd at the CareerBuilder Challenge as he makes his first start of 2018. Here are a few early-round, marquee groupings to watch as players battle the three-course rotation in the Californian desert (all times ET):
12:10 p.m. Thursday, 11:40 a.m. Friday, 1:20 p.m. Saturday: Phil Mickelson, Zach Johnson
Mickelson is making his fourth straight trip to Palm Springs, having cracked the top 25 each of the last three times. In addition to their respective amateur partners, he'll play the first three rounds alongside a fellow Masters champ in Johnson, who tied for 14th last week in Hawaii and finished third in this event in 2014.
11:40 a.m. Thursday, 1:20 p.m. Friday, 12:50 p.m. Saturday: Jon Rahm, Bubba Watson
At No. 3 in the world, Rahm is the highest-ranked player teeing it up this week and the Spaniard returns to an event where he finished T-34 last year in his tournament debut. He'll play the first two rounds alongside Watson, who is looking to bounce back from a difficult 2016-17 season and failed to crack the top 50 in two starts in the fall.
11:40 a.m. Thursday, 1:20 p.m. Friday, 12:50 p.m. Saturday: Patrick Reed, Brandt Snedeker
Reed made the first big splash of his career at this event in 2014, shooting three straight rounds of 63 en route to his maiden victory. He'll be joined by Snedeker, whose bid for a Masters bid via the top 50 of the world rankings came up short last month and who hasn't played this event since a missed cut in 2015.
1:10 p.m. Thursday, 12:40 p.m. Friday, 12:10 p.m. Saturday: Patton Kizzire, Bill Haas
Kizzire heads east after a whirlwind Sunday ended with his second win of the season in a six-hole playoff over James Hahn in Honolulu. He'll play alongside Haas, who won this event in both 2010 and 2015 to go with a runner-up finish in 2011 and remains the tournament's all-time leading money winner.
