Old Belvedere continue to impress on their return to Division 1A rugby, moving to the top of the table after beating Ballynahinch 32-17 at Ollie Campbell Park.

Belvedere, champions of the Energia All-Ireland League's second tier last season, had two tries from powerful prop Ryan McMahon, and replacement Joe White went over for an 81st-minute bonus point score.
