Three goals in the last 18 minutes gave Joe Public a 4-2 victory over M&M Harvard, their second in as many matches in the bmobile National Super League, on Sunday at Trinity College Ground in Moka.
Glen Walker drew level for Harvard in the 35th, after Antoine's tenth minute effort, and on the other side of half-time, Shatton Ollivierre sent Harvard ahead in the 60th. But Thornhill's brace tilted the match in Joe Public's favour, handing them the victory.
That result leaves Joe Public second in the standings on goal difference to Economy Strikers, whose two first half goals handed them a 2-1 triumph over winless ALCOA Carenage United at the Sangre Grande Recreation Ground.
T&TEC are third, also on goal difference with the leaders, after eking out another come-from-behind win against the Defence Force.
Sherman "Ants" Phillip sent the Army-Coast Guard men ahead in the 20th, but the "Electricity Men" had two first half goals from Kefim Williams and Gerron McKnight to earn the win at the Manny Ramjohn Stadium, Marabella.
Club Sando were also winners, coming away from Canaan in Tobago with a 3-2 victory over 1976 Phoenix Sports Club thanks to a Malon Lewis double and another goal from Kyle Morgan.
The other two matches ended in draws, with East West Coaching School holding Harlem Strikers 0-0 at Frederick Settlement for their first Super League point, and it was 1-1 between Queen's Park Cricket Club and WASA FC at St Anthony's College Ground in Westmoorings.
The next round of matches will be played on Sunday.
