Newcastle Jets demolished Central Coast Mariners 8-2 in Saturday's F3 derby in the highest-scoring match in A-League history.
The second-placed visitors scored five goals in the last 37 minutes in a madcap encounter at Central Coast Stadium to conclude their regular season in style and send the Mariners to the bottom.
Ernie Merrick's side had lost their previous three games but they looked set to get back to winning ways after only 24 minutes, with Joseph Champness, Roy O'Donovan and Riley McGree putting them 3-0 up.
Connor Pain, who had earlier hit the post, got a goal back before half-time but McGree struck his second 53 minutes in to set up an extraordinary remainder of the match.
Lachlan Jackson headed in Dimitri Petratos' corner before O'Donovan struck the sixth from the penalty spot, and McGree completed his hat-trick with a composed finish 15 minutes from time.
Trent Buhagiar fired in another consolation but Petratos got in on the act barely a minute later, as the Jets hit eight goals in a single game for the first time.
15 - @NewcastleJetsFC have set the record for the most goals against a single team in an @ALeague regular season, scoring 15 goals in three games against the Mariners this campaign (5-1, 2-0, 8-2). Annihilate. pic.twitter.com/xFM0B37Jcp— OptaJason (@OptaJason) April 14, 2018
The Mariners finish bottom of the table due to Wellington Phoenix's earlier 2-1 win over Melbourne City.
Bruno Fornaroli's stunning strike put the visitors ahead at QBE Stadium before a double from Sarpreet Singh sealed the comeback win.
In the day's late match at nib Stadium, Brisbane Roar kept their finals hopes alive with a 3-2 victory over Perth Glory, who remain eighth.
Two goals from substitute Henrique, either side of a Thomas Kristensen strike, saw the visitors come from a goal down to claim the three points against a Glory side who saw a late penalty saved by Jamie Young.
Roar are up to sixth in the table but will need Adelaide United to take points off Western Sydney Wanderers on Sunday to guarantee their finals spot.
