Five minutes later, Velazquez scored his second goal – a blistering 20-metre drive into the top right-hand corner.
Wainui started briskly, scoring 10 minutes into the match. A well-worked move through the midfield ended with winger Gonzalo Dotta making a run in behind the defence and guiding his shot into the corner of the goal.
Velazquez belted in the second goal from 22 metres, and five minutes before the break right-back Macario Mangiacabailli climbed high to head in a corner and make it 3-0.
Stirton said Alex Larkins had another good game at centre-back, Dotta caused HSOB plenty of problems on either wing, and Velazquez made things happen from midfield.
HSOB player-coach Matt McFatter said striker Oscar Williams was his side’s man of the match and right-back Robert Ford was next best in a good team performance.
“The boys were a bit unlucky,” McFatter said.
“Wainui played really well and got away to a good start but I don’t think the score reflected the game. We missed three or four chances and Wainui put theirs away.”
