Tanjong Pagar United made the trip to the Clementi Stadium for the second Group B match of their StarHub League Cup campaign against Tampines Rovers on Sunday evening.
The Stags dominated the proceedings and deservedly came out 2-1 winners, courtesy of a first-half brace from Aleksandar Duric.
Ismael Benahmed pulled one back in the closing seconds of the game but there was not enough time to complete a comeback.
