|Match winner - Labi|
Jirawat Khaewboran put the home side in front on 20 mins when he headed home Labi's cross following a jinking run from the African.
Santi levelled for Suphanburi 10 minutes later with a sweetly taken free-kick.
Midway through the second period, Labi put the Hares back in front when he latched on to a weak back pass from Suphanburi's Jorrin John.
A few minutes later, the away side were reduced to 10 players as goalscorer, Santi, was sent for an early shower after receiving two yellow cards.
Despite having a man advantage, Chantaburi held on nervously for the last 20 minutes as Suphanburi couldn't force a late equalizer.
