The second string Mohun Bagan looked to take the lead in the 14th minute but the woodwork came to the rescue of the champions of 2016 Dhivehi Premier League and Maldivian FA Charity Shield winners.
It was Balwant Singh, whose shot was tipped over by custodian Pavel Matiash.
The Maldives outfit were reduced to 10 players after Milos Kovacevic got his second booking within four minutes bringing down Azharuddin Mallick.

Mohun Bagan had another chance in the fourth minute of stoppage time but that too went abegging with Balwant's header being off-target.
