Michael Dunlop won the Open race while brother William took the Supersport 600cc honours at Saturday's Skerries road races.

Michael, riding his MD Racing Superstock BMW bike, overhauled long-time leader Derek Sheils to take the flag by 0.5 seconds after seven laps.

William had to settle for third in that event but went on to win the Supersport class from Derek McGee and Michael.

Davy Morgan was the 250/400cc victor, with Seamus Elliott second.
