Mike Reid shot a two-under-par 69 Saturday and moved one shot in front of Severiano Ballesteros after three rounds of the $600,000 Westchester tournament at Harrison, N.Y.
Reid, a winner of more than $1 million who has not won in 11 years on the PGA Tour, completed three trips over the Westchester Country Club course in 203, 10 under par.
Ballesteros, a Spaniard who has won two Masters and a pair of British Open titles, surrendered the lead in a head-to-head battle with Reid and struggled to an even-par 71.
Officials questioned Ballesteros about a possible rule violation that was discussed by national television commentators.
Numerous viewers telephoned officials claiming that Ballesteros' ball moved when he grounded his club behind it while in deep rough near the 14th green.
"The ball shook a little because the grass was very fluffy," Ballesteros said. "It shook. But it did not change position.
After questioning Ballesteros and viewing film, officials determined there was no violation.
Chris Perry, son of former major league pitcher Jim Perry, had a tie for second until he put his third shot on the par-5 18th into a bunker and eventually settled for a bogey.
He finished with a 67 and was two shots off the pace at 205.
