The visiting team got their first two goals of the match through New Zealander Simon Child, in the 5th and 47th minutes, before India international Harmanpreet Singh reduced the margin for Mumbai with a penalty corner goal in the 51st minute.
Any hopes of Mumbai coming back and drawing the game through a late goal as they did in their opening game against Punjab Warriors was botched when Australia’s Jason Wilson
found the mark two minutes from the end – the visitors’ third field goal of the game – to complete the rout.
Delhi had beaten Mumbai by the same score-line in their first-leg encounter and the victory was their second in five games in the tournament, both notched against Mumbai.
Mumbai continued to remain winless in the league following their third loss in five games and remained at the bottom of the six-team table.
Delhi were clearly the superior team, faster on the ball and faster to recover after staving off a raid.
Their current India players – skipper Sardar Singh and right back Gurbaj Singh – controlled the flow of moves beautifully.
Up front, Child, Steven Edwards, Wilson and Akashdeep Singh looked sharp.
Mumbai, on the other hand, lacked in speed and cohesion and could not penetrate the rival circle as they wanted to do.
Australian Glenn Turner again looked a forlorn figure up front without adequate support from the rear.
The opening goal of the game came as early as the fifth minute.
