The Scottish Championship side caused an upset by booking their place in the final.
Dominic Ball has suggested to Rangers' official website that the lightning start Mark Warburton's men made to the Old Firm Scottish Cup semi-final was a key reason why they ultimately managed to book their place in the final.
The Gers may have been in the division below going into the game against Celtic, but they certainly looked like the side that was sitting at the summit of the top flight rather than in the Scottish Championship, and were rewarded as they won the penalty shootout following a 2-2 draw after extra-time.
And Ball has claimed that their victory all stemmed from the momentum they got in the opening stages of the contest at Hampden Park.
"In the games that we've played when we've started really well, I think we've gone and won the games," he told the club's official website.
"So that was really important for us to go and impose our style on the game, and we did that and they couldn't live with us."
With the game being only the second meeting between the rivals since the Light Blues were demoted from the top tier four years ago, and with their opponents well on course for their fifth Scottish Premiership title in a row, some may have assumed that Rangers' game-plan would have been cagey and designed to frustrate the Hoops for as long as possible.
However, they settled into the game much quicker and were rewarded with a 16th minute goal from Kenny Miller. And while Celtic would equalise twice, it was the Gers that dominated much of the play, with their intricate passing and energy clearly taking the opposition by surprise and helping them book their return to Hampden for next month.
