Dickerson, a 20-year-old junior at the University of Florida, came from 1-down through 15 holes in his match against Brian Nosler to win 1-up.
The match was marked with a bit of controversy, as neither player would concede short putts, but it ended in unparalleled drama, as Dickerson rallied with a Tiger Woods-like flair.
The Hilliard, Fla. native pumped his fist after holing a long chip shot for birdie at the 16th to even the match, and then drained a 40-foot bomb for birdie at No. 17 to pull 1-up.
When faced with an 8-foot putt for par to seal the deal at the closing par-3 18th, he sunk it.
Similarly, Hamilton came back on the back nine in his win Saturday, but it wasnt so much for great play as it was for poor golf from his opponent Manuel Merizalde.
One-down through 11 holes, Hamilton, 24, won four straight holes by simply making pars, as Merizalde struggled with three bogies and a double-bogey.
The Columbia native attempted a comeback with a hole-winning birdie at the 16th, but could not muster any more firepower, finally losing 2-and-1.
The final match is set for Sunday, and will be contested over 36 holes at East Lake.
Both Hamilton and Dickerson received invites to next years Masters Tournament with their semifinal wins.
Sundays champion will also gain entry into the 2002 British and United States Opens.
