Ian Westwood edged a boundary off the last ball to earn Warwickshire a tie from an eventful Twenty20 Cup game against Gloucestershire at Bristol.
The visitors needed 82 off their last six overs to reach a target of 159, and almost got there thanks to Tony Frost's 53 off 33 balls.
Gloucestershire's total of 158 for 4 was built around an opening stand of 60 between Craig Spearman and Hamish Marshall, who top scored with 46.
Durham cruised to a six-wicket victory against Leicestershire at Grace Road. A fifth-wicket partnership of 52 in four overs between Dale Benkenstein and Albie Morkel saw Durham through to their second win of the week in the Northern Division.
South African all-rounder Andrew Hall was the star of the show as Northamptonshire hammered Worcestershire by 33 runs at Wantage Road.
Hall – who had hit an unbeaten 66 in Northants' 182 for 4 – took six wickets at a cost of only 21 runs in his four overs as Worcestershire slumped to 149 all out.
Northants are top of the Midlands, West & Wales Division after two victories from as many games.
Kent opener Joe Denly struck 52 from only 33 balls as they beat Surrey by 13 runs at The Oval.
