For the second consecutive day, David Frost was as hot as the sultry Memphis weather, tying a PGA Tour record with his second 63 for a four-shot lead in the St. Jude Classic.
Five other golfers also have shot 126 for the first two rounds of a PGA tournament. Among them is John Cook, who set his mark in the 1996 St. Jude, also played at the par-71 Tournament Players Club at Southwind.
Frost did not play St. Jude that year, but recalled watching it on television and thinking, "How the hell can a guy shoot those scores?"
"I obviously didn't expect to shoot two 63s," he said. "Last year, I shot two 71s and missed the cut. So I was just trying to improve on last year's two 71s.
"I'm very happy with the way I've played the last two days. Hopefully, it will just snowball over the next two days."
Hal Sutton, who was tied for the lead with Frost and Tom Lehman after one round, shot a 67 and was alone in second at 12 under, four shots back.
LPGA: Jean Zedlitz, displaying unusual composure after years of failure on the tour, fired a 1-under-par 71 to grab a two-stroke lead midway through the Rochester (N.Y.) International.
"I've kind of made a commitment to myself to just go play well and have fun and enjoy it while I can," said Zedlitz, who moved to 5-under-par 139. "Whatever happens happens."
Sweden's Eva Dahllof carded a 70 to join Leigh Ann Mills and Cindy McCurdy at 3 under. Australia's Karrie Webb, the leading money-winner this year, roared into contention with a 67 that moved her to 2 under along with Liselotte Neumann and Tammie Green.
South Korea's Se Ri Pak, struggling to regain the form she displayed as a rookie last year, fired a 66 -- the second round's best score -- to claw her way back to 1 under.
Michele Redman, who had shared the first-round lead with Zedlitz, fell away with a 79. Defending champion Rosie Jones carded a 69 to get back to even par.
SENIORS: Jim Albus birdied four straight holes en route to a 7-under-par 65 for the first-round lead in the BellSouth Senior Classic in Nashville.
Albus held a one-shot lead over David Lundstrom, who got into the tournament as an alternate when Allen Doyle was forced to withdraw, and Howard Twitty, who toured the 6,783-yard Springhouse Golf Club course in a pair of spiked sandals designed to relieve his ailing feet.
Two strokes back were John Mahaffey, Harold Henning, 1997 BellSouth champion Gil Morgan, Al Geiberger and Joe Inman, who lost to Doyle last week in a playoff.
