The Commercials club man had just entered the fray as a blood sub when he was twice involved in the move that finished with Boland goaling from close range in the 44th minute.
Within seconds he was back on the sideline, but when introduced again 11 minutes from time, Fitzpatrick fired over a point that would prove crucial.
