Jamual McAlister was MVP, with 28 points, eight rebounds, seven assists, and three steals. The 5ft 10ins guard set the tone for the game by opening Trinity's account with a well worked fast-break lay-up.
To be fair, the MVP could have also gone to Rafi Jalloh (28 points) or Isaiah Alakui (24 points), who also played exceptionally well.
Causing trouble for Northampton was Ethan Round, who left the court with a consolatory double-double of 33 points and 10 rebounds.
The first half ended with Trinity sitting comfortably 18 points ahead.
Isaiah Alakui made a lovely pop-pass assist to Rafi Jalloh to split the defence for a lay up, before Round nailed a turn-around jump shot to bring the half to a close.
However, the lead was already too large for the boys in red to chase down. Trinity then stayed in control for the rest of the game.
Wow. One for the ages.

CoLA's success knows no bounds, with the Southwark academy's girls team also winning their under-17 final.
