Strikers gambled and held off taking the power surge until the 18th over with 33 runs still needed. It proved a masterstroke after they scored 24 runs culminating in a huge six over deep square leg from Patterson, who was unruffled by the situation.

After Amelia helped steady the ship, Heat needed a lift from Laura Harris who again obliged with power-hitting.
