Schools Rugby: Keith Earls was the hero as St Munchin's cruised to the semi-final of the Munster Senior Cup at Thomond Park yesterday.

But he tarnished his excellent display when he was red-carded after 66 minutes when he was dismissed for punching.

Earls scored a splendid opening try after 20 minutes, which he converted, and created try number two for fullback James O'Dwyer.
