Robbie Frylinck's sensational knock was not enough as Dolphins exited the Champions League Twenty20 with a 16-run loss to Lahore Lions.
Chasing 165 after a fine 73 not out from Umar Akmal had helped Lahore to 164-5, Dolphins appeared set for a heavy defeat in Saturday's Group A clash when they were reduced to 93-9 with just 26 balls remaining.
However, Frylinck, celebrating his 30th birthday, turned things around spectacularly by backing up a bowling performance that had seen him take 3-22 with a magnificent 63 not out.
But, for all Frylinck's heroics in Bangalore, the total proved beyond the reach of Dolphins, who bowed out as Lahore regained their composure in the final overs to restrict the South African side to 148-9 and seal victory for the first time in the competition.
The win puts the Lions on six points, with their ambitions of a last-four place still intact ahead of a final group-stage encounter with Perth Scorchers.
At 34-4 in the eighth over the Lions looked to be heading towards a disappointing total, but the introduction of Umar to the crease changed the pattern of the game.
The 24-year-old hit 10 boundaries in a brutal display of hitting to rescue the Lahore innings, his partnership of 92 with the superb Saad Nasim (43) " who was eventually trapped lbw by Frylinck " helping the Lions to a score that looked improbable in the early stages of the innings.
Lahore carried the momentum from Umar's inspiring performance into their bowling display, which saw them quickly remove Cameron Delport and Keshav Maharaj for ducks and Cody Chetty for just two.
The departure of Morne van Wyk for 36 seemed to have ended Dolphins' hopes as the middle order, save for Jonathan Vandiar (29), wilted with little resistance.
Yet Dolphins found an unexpected talisman in Frylinck, whose remarkable innings featured six sixes, four of which came in a wonderful 18th over.
Frylinck was unable to complete the fightback, however, with strong death bowling from Mustafa Iqbal (2-21) and Wahab Riaz (1-31) preventing him from staying on strike as the Lions survived.
