Johnson entered the day with a one-stroke lead and remained steady at the start of the weekend, producing some impressive approach shots throughout the day:

He finished with a 65, including six birdies, putting him in good shape to possibly bring home his second win of the season.

It wasn't easy to pull away from Putnam, though, who completed a bogey-free round with six birdies.

The 29-year-old finished with a 64, tied for the best round of the field on Saturday, as he seeks his first PGA Tour victory.

Stewart Cink was the other player with a 64, becoming one of the big movers of the day while jumping from 14th place to third. He was especially impressive on the par threes with two birdies and a hole-in-one on No. 8:

With a 68 or better in all three rounds, the veteran remains in contention to bring home a title.

Trey Mullinax also rose quite a bit in the standings as well after shooting a 65.

Phil Mickelson fell far out of contention after shooting a 73 in Round 3. He had three bogeys and a double, dropping him to one-under for the tournament.

On the plus side, he did have a few highlights to help prepare him for next week's major:

There is still a tournament to win in Memphis, however, and the leaders will battle for their share of the $6.6 million purse during the final day of action Sunday.
