Gareth Delany's flying start at the top of the order propelled Ireland Wolves to a 51-run win (DLS) over Bangladesh A at Malahide to level the series and set up a decider at Malahide on Friday.
The Leinster opener smashed 37 from just 15 balls, hitting 5 fours and 2 sixes as he and Stuart Thompson added 58 in just 28 balls in a partnership which set the tone for the innings.
Thompson hit 47 from 38 balls (5 fours, 1 six) adding 75 win 55 balls with William Porterfield, who found the boundary seven times in his 45.
The Irish finished strongly, adding 68 in the last six overs with Kevin O'Brien's 30 from just 13 balls the highlight - he hit 3 fours and 2 sixes before being run out, while Andy Balbirnie (18) and Simi Singh (12) kept the momentum going to the end.
A final total of 202 for 6 was always going to be a challenging one for the tourists, and so it proved as the Irish got off to a strong start.
The bowling unit reduced Bangladesh to 67 for 7, with two wickets apiece for David Delany (cousin of Gareth) and Andy McBrine.
Simi Singh, George Dockrell and Barry McCarthy all claimed one apiece - the latter thanks to a superb piece of athleticism by Stuart Thompson, who leapt to prevent the ball going for six, parrying the ball back into play for Gareth Delany to claim the catch.
It was reflective of the Wolves' play on a day where everything went right for them.
Bangladesh rallied to 104 for 7 in 15 overs before a heavy shower finished play - Ireland 51 ahead on DLS.
"It was again brilliant to bounce back and all our batters fired from ball one," said skipper Andy Balbirnie.
"Special mention to Gareth Delaney who came in for his first game of the series and set the tone with the bat.
"All the bowlers did well and took wickets when asked, which was backed up with our fielding. A real complete performance going into the final game."
Ireland Wolves Head Coach Pete Johnston paid tribute to his team, and also to Malahide for hosting the extra match at short notice after Wednesday's match was washed out.
"Firstly credit to Malahide Cricket Club for facilitating today’s refix and also our Manager Chris Siddell and Events Team who all worked closely together. I thought Head Groundsman Philip Frost produced an outstanding T20 pitch.
"As a team we have spoken about playing this format with freedom and enjoyment. I thought Gareth Delany and Stuart Thompson set the tone with their partnership in the first 6 overs and all the batters after that carried on in the same vein putting pressure on the bowlers with all of the top 4 passing 30 with healthy strike rates.
"It was particularly pleasing to see the boundary count so high pushing 30 and almost double what we got in the last T20, that clearly is the difference. Passing the 200 mark on good pitches is exactly what we need to be doing to become competitive in this format on the World Stage.
"I thought the Bangladesh seamers hit some good Yorkers and managed to find reverse swing, so it was far from easy out there today.
"Taking four wickets in the power play with the ball was again a positive point of difference and our bowlers who nearly all contributed with wickets backed up the batting performance, while in the field we took our chances and created an outstanding play between Gareth Delany and Stuart Thompson combining for a catch on the ropes.
"We will rotate a couple of players in the final game and try out some different combinations, but we will be ready for what should be a really competitive series decider."
Play in the decider at Malahide gets under way at 4pm.
