Andrew Putnam matched the best round of his short PGA Tour career with a 6-under 64 and tied Dustin Johnson atop the St. Jude Classic on Saturday in Memphis, Tenn.

In position to reclaim the No. 1 ranking with a victory, Johnson had a 65 to match Putnam at 15-under 195.

A two-time winner on the Web.com Tour, Putnam birdied No. 18 to tie up Johnson once again after a bogey-free round. Now he will play in the last group on the final day for the first time on the PGA Tour with Johnson.

Stewart Cink, who had a hole-in-one on No. 8, matched his low round of the year with a 64 to get to 10 under.

Ricky Werenski got to 10 under but bogeyed No. 18 to finish with a 68. He was tied with Bryan Wesley (69) at 9 under. Brandt Snedeker (70) was at 7 under.

Johnson and Putnam, a 29-year-old from Washington with two Top 10s this year on tour, quickly turned the third round at TPC Southwind into a two-man race.

Akron native Harold Varner III (72) is tied for 58th.

LPGA Tour

Sei Young Kim birdied seven of her last 10 holes for a share of the lead with Celine Herbin in the suspended second round of the ShopRite LPGA in Galloway, N.J.

Kim was 10 under for the tournament with three holes left when play was suspended because of darkness.

Herbin had her second consecutive 5-under 66.

Herbin birdied No. 18 after play resumed following a delay of nearly three hours because of lightning strikes in the area. The Frenchwoman left her job as a biochemical engineer at age 27 to become a professional golfer.

Herbin had made the cut in just five of 11 tournaments prior to this week.

Kim, a six-time LPGA Tour winner, was one of 36 players unable to complete the round.

Mariah Stackhouse (65), Annie Park (65), Ashleigh Buhai (66) and Su Oh (two holes left) were 2 strokes back. Stackhouse is trying to become the tour’s first black winner.

Two-time champion Anna Nordqvist had a 73 to drop from a tie for first to a tie for 34th at 3 under.

Champions Tour

Tom Lehman might finally get an elusive senior victory in Iowa after so many close calls.

Lehman shot a 7-under 65 to take a 2-shot lead into the final round of the PGA Tour Champions’ Principal Charity Classic in Des Moines, Iowa.

Lehman eagled the par-5 eighth and played a 10-hole stretch in 7 under before dropping a stroke on the par-4 18th. He had a 13-under 131 total, the best two-round score at Wakonda Club.

From neighboring Minnesota, Lehman has finished in the top 10 in each of his first six appearances in Iowa, but the 1996 British Open champion has never won the event.

First-round leader Bernhard Langer had a 69 to fall into a tie for second with Glen Day (68), Woody Austin (68) and Scott Parel (66).
