Jordan Spieth wins "Big 3" matchup on Day 1 at WGC-Cadillac Championship

March 03, 2016

The premier group of Jordan Spieth, Jason Day and Rory McIlroy didn't disappoint on Thursday at the WGC-Cadillac Championship.

Spieth was the best of the bunch, carding five birdies on the day to turn in a three-under 69, three behind clubhouse leader Scott Piercy. In it's redesign, Doral tends to favor longer hitters, seemingly a detriment for Spieth against bombers like Day and McIlroy. Yet the 22-year-old used a steady approach game to set the pace, including here on the first hole, his 10th of the round:

McIlroy played well for most of the day, hitting 15 greens. However, his new left-hand low putting grip was a bit of a disaster, converting just two putts between five and 10 feet and making just one over 10 feet.

While he was three-under through 17 holes, McIlroy threw one in the water at the last, taking a double and finishing with a one-under 71.

Day had a bit of a roller coaster round. Dealing with flu-like symptoms, his four birdies were offset by four bogeys. But, for not having his "A" game, the Australian will take his 72 at Doral's difficult set-up.
