First round co-leader Alvaro Quiros stumbled a bit on Friday, recording a one-over 73. The Spaniard stands at six under through two rounds.
Then, there's a group of three golfers tied for fifth at five under par. They include former Masters champ Fred Couples, who shot a four-under par 68.
Other notables include defending Masters champ Phil Mickelson, who shot an even-par 72 Friday and remains at two under. Tiger Woods is still on the course and is at two under par after nine holes in his second round.
