Zimbabwe made 144 with captain Craig Ervine top scoring on 42 and Ireland knocked off the runs with two balls to spare, setting up a series decider on Sunday.

A former Ulster rugby player, Adair faced 47 deliveries and struck four sixes and two fours at Harare Sports Club.

It was a huge change of fortunes for him as he made only five runs in his international debut on Thursday, with Zimbabwe winning by five wickets.

Adair departed after trying to clear long-on off left-arm quick Richard Ngarava, miscuing his shot and picking out Wessly Madhevere.

"My switch to cricket was purely for fun, then I started scoring runs and took it more seriously," said Adair, whose younger brother Mark was also part of the winning team.

"I took my time today and it paid off. I knew if I was patient, the boundaries would come. We pat ourselves on the back, and come back again tomorrow."

When Adair departed, Ireland were 119-3 and needed 26 runs from four overs to win. Tector departed with nine still required before George Dockrell hit a six to secure victory.

Leg spinner Ryan Burl was the best of the Zimbabwe bowlers, taking two wickets for 26 runs in his four-over spell.

With former England Test batter Gary Ballance ruled out by concussion and star Sikandar Raza playing franchise cricket in Bangladesh, Ervine assumed the mantle of chief run-getter.

Put in to bat after losing the toss and one wicket down with just six runs on the board, Ervine took charge with his 40-ball innings, which included four fours.

He was undone when attempting a scoop shot off a back-of-a-length delivery from Graham Hume, top-edging it to fine leg where Tector made the catch.

"We worked pretty hard to set a decent platform of 160, 170, 180 runs," said Ervine. "But Ireland bowled well and made it difficult for us to get boundaries."

South Africa-born Hume, promoted in place of Barry McCarthy, was the most effective of the Irish bowlers taking three for 17 while Tector took two for 22.
