After seeing his opening partner Emmanuel Bawa fall for three runs, Matthew Welch added 32 runs for the second wicket alongside Panashe Taruvinga, with Taruvinga contributing just three runs before being dismissed by Jack Jarvis.
Welch then advanced passed fifty, as did Brian Bennett whose 54 off 58 balls helped Zimbabwe reach 155 in the 31st over.
Bennett was then forced to go, bowled leg before wicket by Lyle Robertson as he was replaced in the middle by another Bennett, David, who worked with Welch to move Zimbabwe closer to 200 before Welch fell for 78.
Jarvis then swung the game back in Scotland’s favour taking two wickets in two balls to reduce Zimbabwe to 221 for seven and remove the dangerous Rogan Wolhuter.
His hat-trick ball came in his next over and while he could not get the scalp of Tendekai Mataranyika he soon bowled Connor Mitchell to leave Zimbabwe reeling.
Alex Falao was the final wicket to fall as Zimbabwe ended on 248 all out, meaning Scotland would have to post their highest score of the tournament to win.
In reply, Scotland were restricted by good bowling from Zimbabwe, Charlie Tear was first to go bowled leg before wicket by Mcgini Dube before Bennett and Bawa got in on the act.
Left-arm spinner Mitchell then picked up the next three wickets as Scotland slumped to 105 for six with 26 overs remaining.
Scotland’s collapse continued as Bennet also claimed a threefer including the final wicket of Ruaridh McIntyre to bowl out Scotland for a 108-run win and to advance to the Plate League semi-finals
