For the second straight game, the Monarchs couldn't generate offense, falling to Atlantic Division-leading Providence, 3-1, at the Dunkin' Donuts Center on Sunday.
Manchester (29-26-3-4) is in 10th place in the Eastern Conference with 65 points. Manchester, with 14 games left, is tied for ninth with Albany and is three points behind seventh-place teams Hershey and Connecticut. The top eight teams qualify for the conference playoffs.
"We actually played fairly well," said Monarchs head coach Mark Morris. "The result wasn't great but I felt we competed a lot harder and tried to execute the details of the game."
Manchester opened the three-game weekend with a 3-2 home win against Bridgeport on Friday. On Saturday, the Monarchs were 0-for-7 on the power play and lost 3-0 to the host Whale.
