This trio combined for four straight victories at Colonial, with Johnson hoisting the trophy in 2010 and 2012 while Toms won in 2011 and Weekley was victorious in 2013. The player coming in with the best form of the group is Johnson, who has recorded five top-20 finishes in his last six starts and also strung together five straight top-10s at this event from 2009-2013. Toms' T-13 finish at TPC Sawgrass was a rare bright spot amid a difficult season, while Weekley finished third at the Zurich Classic last month.
This group will reunite last year's playoff participants, as Scott defeated Dufner in overtime to win the fourth and final leg of the Texas Slam. Scott was No. 1 in the world last year but now returns outside the top 10, with his putter solely to blame for his recent struggles. Dufner's lone top-10 finish this season came at the WGC-HSBC Champions in November, while Reed is making just his second appearance at Colonial after a T-46 finish in 2013.
These three have won four times on the PGA Tour since January, with Walker capturing a pair of trophies. He returns to Colonial after a T-10 finish last year. Snedeker hasn't had a top-10 since his victory at Pebble Beach in February, and his best result in this event came in 2011, when he finished T-16. Hahn has yet to crack the top 25 in five starts since his breakthrough victory at Riviera.
Spieth is No. 2 in the world and headlines this field, with No. 1 Rory McIlroy playing in Europe. He will have plenty of support from the crowds in his native Texas, and Spieth's first two trips around Colonial resulted in top-15 finishes. He'll be joined by Mahan, whose lone top-10 finish in 11 Crowne Plaza starts came back in 2011, and Stricker, a winner of this event in 2009 who last teed it up in Fort Worth in 2010.
