Cameron McKinley and Rhys Watson took three wickets each.
The Bulls were 0-93 at the end of play, with Mili Sepala 59 not out.
Meanwhile, Diggers Rest Bulla pulled off a miraculous victory against Woodend.

Lindon Dowsett got the wicket of Thomas Boyer before James Morley fell four runs later to Darren Quarrell. Kevin Barker then got the big wicket of Josh Eastley for 53, leaving Woodend needing four runs with one wicket in hand.
Quarrell finished the match with his seventh wicket, giving the Burras a three run win. Quarrell finished with the figures of 7-55.
