He can trace his misfortune back to round two, held at Himatangi, near Palmerston North, three weeks earlier.
Waitakere's Martens, riding the Yamaha YZ250 two-stroke, had qualified fastest at round two, with Lamont taking his four-stroke YZ250F to qualify second fastest that day.
Lamont then finished runner-up to Harwood in the first race in the Manawatu. But then Lamont's championship bid fell to pieces when he crashed, banged his head and failed to finish race two. That was the end of his day - he did not line up for race three in the Manawatu - and it resulted in him recording two non-scoring races, a tragedy when the entire season comprises just 12 races.
"I won two out of three races today (at Taupo) ...
"I wasn't too worried about winning the last one because I wasn't in a 'do or die' position," said Lamont.
"I couldn't gain anything more by winning the last race, plus I'd tweaked my knee. I'd win the day (with a 1-1-2 score-line) and moved myself up to third in the series, so that was enough."
