Gloucestershire moved up to second place in Group A of the Clydesdale Bank 40 after overcoming Worcestershire by four wickets in a low-scoring encounter at Cheltenham.
Captain Alex Gidman starred for the Gladiators, taking 3-20 with the ball to restrict Worcestershire to 144-7, and then steering his side past the victory target with an unbeaten 33.
The two points gained sees Gloucestershire leapfrog Middlesex into second spot, just two points adrift of Netherlands with two games in hand.
Australian Phil Hughes continued his impressive form for Worcestershire with an unbeaten 64 after the Pears had been inserted on a damp track.
The tone of Worcestershire's innings had been set by the very first ball of the match from Ian Saxelby, though, which Moeen Ali edged through to wicketkeeper Jon Batty.
Soon it was 21-3 as Vikram Solanki miscued a pull shot off Liam Norwell to James Fuller at mid-on and James Cameron was caught behind driving at Norwell for a duck.
Gidman claimed the wickets of opposite number Daryl Mitchell, Neil Pinner and Gareth Andrew to reduce the Pears to 89-6 in the 29th over as Hughes began to run out of partners at the other end.
The left-hander eventually reached his half-century off 93 balls, including four fours, and finished unbeaten on 64 from 108.
Gloucestershire threatened to make a mess of the run chase when they plunged from 51 without loss to 81-5 in reply, only for Gidman to steady the ship.
The Gladiators skipper shared a key sixth-wicket stand of 47 with Ed Young (28) as his side won with 12.5 overs to spare.
Spinners Moeen Ali (3-33) and Brett D'Oliveira (2-35) had threatened to bowl Worcestershire back into the game, but Ed Cowan (29) and Hamish Marshall (26) had given the hosts a brisk start chasing down their modest target.
