Jordan Spieth is back to defend his title at the Valspar Championship at one of the best courses on the Florida swing. Here are the marquee groups at Innisbrook Resort. (All times Eastern)
Graeme McDowell, Patrick Reed, Hunter Mahan, 7:56 a.m. Thursday off No. 10
McDowell already has a win this season at Mayakoba, plus top-5 finishes at Sea Island and the Honda Classic. Reed, No. 10 in the world rankings, is looking to bounce back from a WD, MC and T-52 in three of his last four starts. Mahan, however, has dropped all the way to No. 87 and hasn't finished better than T-43 in four starts in 2016.
Jordan Spieth, Bill Haas, Henrik Stenson, 8:07 a.m. off No. 10
The defending champion is "struggling" after a T-21, MC, T-17 in his last three starts. But don't fret, Spieth fans, he already has a win and two other top-5 finishes this year. He kick started his incredible run last year at this event, and don't be surprised if he puts up a spirited defense this week. He'll be joined by Stenson, who is coming off a T-28 at Doral and Haas, who has made five of seven cuts this year.
Jason Dufner, Justin Thomas, Russell Knox, 12:46 p.m. off No. 1
Dufner, a winner already at the CareerBuilder, just missed out on a top-10 finish at Doral. Thomas has made three straight cuts after two straight MCs at Sony and Phoenix. He also finished T-10 last year at Innisbrook. Knox, two spots behind Thomas in the OWGR at No. 33, hasn't recorded a finish better than T-26, but he did win the WGC-HSBC Champions in November.
Matt Kuchar, Ernie Els, Louis Oosthuizen, 12:57 p.m. off No. 1
Kuchar is making his ninth-career start at the Valspar. He's only played four events this year, with his best finish a T-8 at Riviera. Els has dropped all the way to No. 208 in the OWGR and is still seeking his first top-10 since the 2014 Hong Kong Open. Meanwhile his fellow countryman Oosthuizen has quietly had a nice start to the year. He's recorded a win in Perth and three other top-15 finishes.
