Rookie all-rounder Sajeevan Sajana hit a six to give defending champions Mumbai Indians a nailbiting last-ball win in Friday's Women's Premier League season opener.
Sajana took the crease in Bengaluru with Mumbai four runs behind the Delhi Capitals in a rerun of the inaugural season's final last year.
Captain Harmanpreet Kaur had been caught at long-on for 55 after attempting a boundary on the penultimate ball.
Sajana then danced down the track, bringing Mumbai to 173-6 and sealing a four-wicket win.
The 29-year-old, a captain for state side Kerala, had been scooped up by Kaur's team in December at the bottom end of the player auction price band.
England all-rounder Alice Capsey top-scored for Delhi with 75.
The WPL was first staged in 2023 and has already proved popular with fans and a lucrative earner for India's cricket board.
Franchise rights were auctioned off last January for $572.5 million, while media rights for the first five seasons were sold to Viacom18 for $116.7 million.
The two deals made the WPL the second-most valuable women's sports league after the WNBA women's basketball in the United States.
