Connacht has scored first through former Leinster man Andy Dunne who landed an 11th-minute penalty after two earlier failures.

Leinster replied in the 20th minute in unusual fashion.

Contepomi was on target with an 18-metre penalty but the wind was so strong it blew the kick back out through the posts and had referee George Clancy reaching for his rulebook before he confirmed the score.

But with that blustery wind behind them, Connacht nabbed an injury-time try.
