Sharp as ever in the first PGA Tour event of the year, Jordan Spieth capped off the third round Saturday with a 10-foot eagle putt for an 8-under 65. He had a five-shot lead over Brooks Koepka going into the final day at the Hyundai Tournament of Champions.

Spieth ran off four straight birdies on the front nine to keep control, then showed off an exquisite short game on the back nine.

Koepka, despite failing to birdie two of the par 5s, had a career-best 63 and at one point got within one shot of Spieth. But the world's No. 1 player holed a 50-foot birdie putt, hit a daring flop shot behind the 15th green to set up birdie and finished with the eagle.

Spieth was at 24-under 195.
