Both sides were through to the play off for the first time.
Tom Hankins took the man of the match award for a four-over burst of 6-36, including the key wicket of Sohail who was caught by all-rounder Anant Tambavekar for 69 which included three fours and six sixes on one of the largest grounds in the Bristol area.
Joe Jenkins, Tom’s nephew, earlier top scored on 62 and Tambavekar hit 30 in Lansdown’s 20-over total of 166-7.
