Nuwan Kulasekara picked up three wickets in 12 balls as Sri Lanka beat Zimbabwe by 19 runs in their fifth and final one-day international on Sunday.
Zimbabwe were chasing just 153 for victory and Keith Dabengwa (39) and captain Prosper Utseya (31) lifted them from 58 for six with a 72-run stand that left the hosts needing 23 for victory in 10 overs with four wickets in hand.
Dabengwa then stepped away and tried to carve Kulasekara through the off-side, only to be bowled.
The dismissal changed the momentum of the game as Zimbabwe gave up their last four wickets for just three runs and lost the series 5-0.
Kulasekara finished with three for 14 in nine overs, and spinner Muttiah Muralitharan completing his 10th five-wicket haul in 318 ODIs, having sparked the initial collapse.
Boundaries were a perk for both teams on a pitch that was low and slow and on which no Sri Lankan batsman, save for Angelo Mathews who scored a run-a-ball 31, looked comfortable.
