The groupings for the first two rounds of the Sony Open in Hawaii have been announced. Here's a look at some of the featured groups at Waialae this week:
Dustin Johnson, Zach Johnson, Johnson Wagner -- Hmm, think you can find the common thread in their names? DJ comes in fresh off his win at the Hyundai Tournament of Champions; Wagner is the Sony Open defending champ.
Keegan Bradley, Matt Kuchar, Mark Wilson -- All three are making the quick trip from Maui after playing in Tuesday's third and final round of the Hyundai Tournament of Champions.
Webb Simpson, K.J. Choi, Vijay Singh -- All three golfers draw big galleries, but Choi -- who won at Waialae in 2008 -- may be the most popular of the three in Hawaii.
John Huh, Jonas Blixt, Tommy Gainey -- Each one broke through with his first TOUR win in 2012. Who'll make the most noise in 2013?
Y.E. Yang, Davis Love III, Mike Weir -- Each a major winner, these three have combined to make 13 appearances in The Presidents Cup.
Luke Guthrie, Scott Langley, Russell Henley -- Three rookies who start their TOUR careers with big expectations. Guthrie and Langley played collegiately at Illinois; Henley at Georgia.
