UL had six points to spare over the hosts, who found things far more difficult than they did in the semi-final against Athlone IT.
Michelle Browne, who scored 2-9 against Athlone, had to be content with 1-1 here, but with both her and Lyng’s goals coming in the first half, it was 1-5 to 1-2 for UL at half-time.
In the second half, they were to add six more, with Lyng and Fiona Lafferty leading the scoring charge, but in defence they were miserly.
Full-back Sabrina Larkin, corner-back Alison Walsh and Mary Ryan at centre-back were all excellent as CIT were restricted to just two points in the second period, and Lyng was rewarded for her brilliant weekend afterwards when she was presented with Player of the Tournament.
In the Purcell Shield, a 59th-minute goal from Keelin Bradley gave Queen’s University, Belfast victory against NUI Maynooth, as they ran out 1-8 to 0-8 winners.
In a tightly contested first half, the sides were level on no less than four occasions, Queen’s going in leading 0-6 to 0-5 at half-time thanks mainly to the accuracy of Collette McSorley, though Louise Walsh seemed to be on a one-woman quest to kept Maynooth in the game.
After the break, Queen’s continued to hold their lead until three points in six minutes, two from Walsh and one from her namesake Catherine, put them 0-8 to 0-7 ahead with only 10 left.
It was the same with the clock showing 59 minutes, but then Bradley found the net to give Queen’s a two-point cushion and McSorley wrapped matters up in injury time.
