Champions Whitehead took over at the top of the NIBA's table following their hard-fought win over nearest challengers Bangor at Islandmagee Road.
Even though they were missing the Beggs brothers -- Stephen and Nigel -- who were away to cheer on Northern Ireland in the 2016 Euro Championships, the east Antrim boys still had too much in the locker for their opponents.

“It’s important to pick up home points, so the seven we got against Dundonald were crucial. More importantly edges us further away form the teams at the bottom. We had a few wee slip-ups in recent weeks, so it was good to get back on track.”
Annesley Harrison was Balmoral’s top performer, skipping his rink to an impressive 33-17 win against Noel Myles.
