After some shaky holes on the front nine, Kaye, from Woodholme Country Club, had not made Klein's tour easy, closing with 12 straight pars to finish 74217. Michael Kuntz of Woodholme wound up third, 73-218.
The final putt by Klein, a Gilman School senior who had missed the cuts in his two previous appearances in what is considered one of the premier amateur events in the state, clinched the victory.
However, the one he made the hole before might have been the decisive stroke of the day.
Klein missed the green at the par-3 17th and chipped to 15 feet, but when he stood over it, Kaye already was in with his par.
"Fifteen feet downhill with a break," Klein said, and he rolled it in for a par.
Jim DeBusk (220) of Chantilly Manor, a perennial contender in this event, and Britt Sloan (222) of Prince George's shared the day's low round with 70s.
A lightning storm forced a suspension of play for 1 hour, 25 minutes. The delay came with the leaders on the ninth tee.
Kaye, bidding to end a series of close but non-winning performances in this tournament, knocked Klein out of the lead with a birdie at the opening hole, but a bogey at the second, a double bogey at the fifth and another bogey at the seventh helped drop him three behind the eventual champion at the turn.
At that point, Klein was plus-1 against par, followed by Sheldon Kalish (plus-2), Buddy Peoples (plus-3), Kaye (plus-4) and Kuntz (plus-5) after starting the round with double bogeys at the first two holes.
Peoples took himself out of it with a double bogey at No. 11, and Kalish did likewise at No. 12. Despite playing his last 16 holes 2-under, Kuntz had too much ground to make up on the leaders.
Klein, who had tightened the chase with a 76 after his opening 67, seemingly brought the field back into it again when he bogeyed the 10th and 11th holes, shrinking his lead to a stroke.
Klein then made three straight pars, birdied the 15th and bogeyed the 16th to set up the dramatic finish in front of 200 spectators. Meanwhile, Kaye had kept his string of pars intact with two marvelous up-and-downs at the 14th and 15th holes.
"I was basically playing for the middle of the greens, looking for pars, but willing to go for a birdie if the opportunity was there," Kaye said. "I was looking for Justin to come back to me, but he didn't crack. He played well, especially considering the circumstances."
Klein was just glad it was over. Ahead of him is a tournament today and a 36-hole qualifier for the U.S. Juniors tomorrow at Green Spring. After that, he's looking at some hard-earned beach time.
Peoples, of Crofton CC, who has been as high as a tie for second in this event, finished fourth, 74219, and Don Bachtell of Fountain Head CC used a par-matching 71 to share fifth with DeBusk at 220. There were two other 71s -- Joe Franz of the CC of Maryland, 221, and Gary Moore, Crofton CC, 226.
Larry Storck of the CC of Maryland, second in three of the previous four years, never really had a chance to improve on that record after an opening 77, and he wound up tied for 16th with 225.
