Resilient Armagh hit back to seal progress in Schools Cup
Harry Burbridge gave Belfast High School an interval advantage but Armagh struck back with three tries to qualify for an away game at Limavady Grammar.
The visiting try came following a scrum around the '22' for No 8 Matty Gregg and Jamie Gallagher to carry before centre Burbridge cut through to score.
The lead at the halfway stage should have been greater but their place kicking was poor.
Armagh coach Gareth Beggs said: "We levelled just into the second half when fifth former Christopher Jennings showed his potential when he scored.
"It came at the right moment and was followed by constructive forward work that led to our tight-head prop Phillip Matthews scoring for Michael Thompson to convert. Then an excellent break by Matthew McSorley allowed him to touch down beside the posts for Thompson to again convert and we were 19-5 in front."
In the last play, Belfast High gained a consolation try when a quickly taken penalty saw Tyler Arnold dash over. Belfast High coach Mickey Rainey said: "It was a well contested tie but we missed too many scoring opportunities and you just cannot afford that if you are to progress."
Beggs added: "We are now away to Limavady and it is a long journey. Home advantage means so much but we will be prepared for whatever they throw at us."
