Worcestershire Seconds completed a T20 double over their Warwickshire counterparts at Kidderminster with openers Brett D'Oliveira and Tom Kohler-Cadmore taking turns at being their side's batting mainstay.
D'Oliveira scored an unbeaten century in the opening game which Worcestershire won by 11 runs and then Kohler-Cadmore hit 79 not out in an eight wicket success in Game Two.
It means the Seconds have won their last four games in the competition to revive their hopes of reaching the semi-finals with the top two in both groups going through.
Warwickshire put the home side into bat in Game One and they responded by amassing 225-4.
D'Oliveira shared in a second wicket stand of 65 in five overs with Alexei Kervezee who hit 39 off 22 balls before he was caught by Will Porterfield at mid on.
Ross Whiteley hit a quickfire 24 off 17 balls while D'Oliveira was expertly picking up singles to rotate the strike.
At this point, D'Oliveira had quietly amassed 40 from 29 balls with just three boundaries but, when he was joined by captain Shaaiq Choudhry, in the 14th over, he stepped up the pace.
He doubled his boundary total in the next over to bring up his half century from 32 balls with four fours and a six and needed only another 21 deliveries to reach his hundred with the addition of another five sixes and two fours.
D'Oliveira's stand with Choudhry (15 not out) was worth an unbroken 87 in 6.1 overs and Worcestershire had six runs added to their total as the visitors were penalised for a slow over rate.
Warwickshire also found the batting track to their liking and in reply were 148-1 after 14 overs, with both Porterfield (51 from 25) and Tom Lewis (82 from 51) going strong.
But, even with this strong platform and nine wickets in hand, the required scoring rate was still 13 an over, so risks had to be taken.
Porterfield was caught by Kervezee at long on in the 15th over to break the partnership worth 102 in 10 overs but Freddie Coleman and Lewis continued to push, leaving Warwckshire 33 to win with eight wickets in hand from the last three overs.
Lewis holed out to D’Oliveira deep in the covers two balls later for 101 but Warwickshire were still in the running at the start of the last over, needing 15 but with only three wickets down.
Chris Russell returned to bowl the final over and second ball Aaron Thomason was caught on the square leg boundary by George Rhodes and Freddie Coleman repeated the exact scenario next ball.
Tom Milnes and Tom Banton could only scramble singles from the last few balls, giving Russell figures of 2-19 from his two overs.
In Game Two, Warwickshire again won the toss but this time chose to bat and first team skipper Varun Chopra came into their side in the opening role.
Lewis was caught at cover by D’Oliveira off the bowling of Russell in the second over and Chopra and Porterfield batted at a much more sedate rate for the next six overs, putting on exactly 50 before Porterfield was bowled by Choudhry.
Chopra started to lift the pace and find the boundary and was flowing on 73 off 43 deliveries when the safe hands of D’Oliveira at mid wicket ended his innings.
Coleman (48) and Jon Webb (40 not out off 23 balls) added 60 until the former was caught at deep point by Alex Hepburn off Russell as Warwickshire closed on 184-4.
D’Oliveira was caught at mid-wicket for eight in the second over but Kohler Cadmore and Kervezee batted sensibly for the next 10 overs, adding 103 and keeping up with the rate without taking too many risks.
Kervezee found the boundary on a regular basis while Kohler-Cadmore played more of an anchor role.
Kervezee was caught at deep mid wicket by Mark Adair on 65 from 32 deliveries including one six and 10 fours.
Ross Whitelely was determined to keep the target within reach, hitting two massive sixes in successive overs, both over mid wicket.
He finished not out on 35 from 19 balls and Kohler-Cadmore remained unbeaten on 73 from 51 deliveries from 53 balls with two sixes and 10 fours.
