World Twenty20 debutants Oman stunned Ireland by two wickets in a thrilling last-over finish on Wednesday with lower-order batsman Aamer Ali's 32-run blitz achieving the target with two balls to spare.

Batting second, the team from the Gulf state scraped to 157 for the loss of eight wickets with two balls to spare after the Irish had put on 153 for the loss of five wickets.

Oman openers Zeeshan Maqsood and Khawar Ali provided a 69-run opening stand only to see the middle-order give it away with the side reeling at 90 for five after 14 overs.

Aamer, who hit five boundaries and a six in his 17-ball stay, then stitched a crucial sixth-wicket stand with Jatinder Singh as Irish medium-pacer Max Sorensen failed to stop 14 runs from the last over.
