Ireland needed 18 overs on the final morning to secure a 63-run victory over hosts Zimbabwe in their one-off Test in Bulawayo on Monday.
Matthew Humphreys finished with 6-57 as he took two of the three wickets Ireland required after Zimbabwe resumed on 183-7, chasing a target of 292 to win. They were bundled out for 228.
Zimbabwe’s faint hopes rested on Wessly Madhevere, who was 61 not overnight, but he was undone by the second new ball when Humphreys bowled him for 84.
The teams begin a three-match one-day international series in Harare on Friday.
