Ulster Schools started their season with a well-earned 20-7 victory over London Irish at Sunbury.
Following a Zac Jordan break, Jonny McKeown touched down after 23 minutes and the advantage was increased three minutes later when a quickly-taken Jonny Stewart penalty led to Phil Jordan giving them a 10-point advantage.
Robert Lyttle added a penalty to make the interval score 13-0 and 15 minutes after the restart, Conor Field won the touchdown following a grubber kick through.
Lyttle added the points but London Irish responded four minutes later to get on the scoreboard and avoid a whitewash when Ulster conceded a five metre scrum which led to a converted pushover try.
Manager Richard Clingan thought it was an outstanding effort against formidable opposition.
"It was an encouraging first outing and it has boosted our confidence before another difficult game at Glasgow next week and then the start of the Inter-Pros," he stated.
Meanwhile, Ulster Under-20s followed their 12-12 draw against Italy earlier in the week by overwhelming the Exiles 76-0 at Newforge.
Manager Terry McMaster commented: "It was an outstanding display of open rugby and it proved our strength in depth as only six players were retained from Monday."
Ulster now travel to London Irish next week.
There are two games scheduled for Newforge today with Ulster Under-18 Youths facing the Exiles at 11.00am.
The Under-19 XV, who won the Inter-Provincial championship last season, taking on their Exiles at 1.00pm.
