Lower-tier side Glow-Lamp Academy edged Accra Hearts of Oak 2-1 in a preseason friendly in Abreshia on Wednesday morning.
Abubakar Traore shot the Phobians in the lead after a frantic start to the game before Solomon Kojo Antwi restored parity for the hosts to end the half 1-1.
Both sides had more than enough chances to win the game after the recess but the most decisive touch of the second half was by Rashad Baba Sulley who scored to secure a famous victory for the Academy lads.
