A stunning unbeaten century from opener Josh Cobb guided Leicestershire to a six-wicket win over the Unicorns in Yorkshire Bank 40 Group C.
After the Unicorns made a healthy 253-8 from their 40 overs, Cobb's 128 off just 108 balls helped steer the Foxes to victory at 256-4 with an over to spare as he and Shiv Thakor put on an unbeaten 136.
It was the 22-year-old's second ton in as many days after he scored 130 in the victory against Somerset on Sunday and contained four sixes and nine fours.
Tom Lancefield's 58 had helped the home side set a potentially testing target at Wormsley but Cobb and Taylor steadied the ship after Leicestershire had been 120-4.
Cobb and Niall O'Brien (24) put on 66 for the first wicket before the Irishman came unstuck off the bowling of Aneurin Norman with Vishal Tripathi taking the catch.
Greg Smith scored 14 before he fell lbw to Luke Beaven and Joe Burns followed for just four as Keith Parsons took a catch off Norman.
And when Matthew Boyce was bowled by Michael O'Shea to leave the Foxes 120-4, the Unicorns may have just been sensing their first win of the season.
But Thakor (64) provided able support for Cobb and sealed the win with a four off the bowling of Devon Endersby.
