A superb bowling and fielding performance by Manchester kept them in the hunt for the second promotion place in the Greater Manchester Amateur Cricket League.
Offerton had no answer to the searing pace of Huddy Lieberman who was almost unplayable and conceded just nine runs from his 10-over spell.
Harry Rosenblum took advantage as he picked up 4-22 from five overs and David Cohen and Shaia Rabinovitz each chipped in with a couple of wickets as Offerton gave away some of their wickets far too easily.
Youngster Gaskell top-scored with 26 coming it at no. 9 to hold up the Manchester advance.
Set a target of 117, Manchester openers Ray Tammam and Steve Glicher calmly went about their task putting on 55 for the first wicket before Glicher fell having scored 20.
The rains then came which threatened to derail the innings, but after a 40-minute wait, Tammam carried on the attack, finishing on 32 not out as Manchester easily reached their revised target of 87.
