Durham Cricket were unable to defend a total 0f 181 as Worcestershire Rapids picked up a nine wicket win at New Road.
Riki Wessels (74) and Martin Guptill (86) made short work of a 182 target as they galloped to half centuries off just 20 and 18 balls respectively.
Alex Lees 44, and what appeared to be a useful knock by debutant Peter Handscomb (37) were the highlights of a Durham innings that saw wickets fall at inopportune times.
But the hosts made light work of the target, reaching the total in 12.1 overs and Durham’s bowlers toiled.
The Rapids opted to bowl and Durham opener D’Arcy Short made a quickfire 23 but then turned a free hit delivery from Pat Brown to mid wicket, set off for a risky single and failed to beat Rapid skipper Brett D’Oliveira’s direct hit.
Ben Raine (6) perished in the next over when he came down the wicket to Pennington and nicked through to keeper Ben Cox. It became three wickets in three overs when Scott Steel (13) sliced Parnell to Ross Whiteley at cover.
His dismissal brought in Durham’s new signing Peter Handscomb who has replaced fellow Australian Cameron Bancroft as one of the club’s overseas players for the remainder of the season.
Handscomb and Alex Lees set repairing the early damage and brought up the half century stand in six overs.
Lees was in a particularly aggressive mood and his 44 off 31 balls included three sixes before he gave Pennington the charge and was bowled to end a stand of 75 in eight overs with Handscomb.
Handscomb (37 off 28 balls) eventually perished at long off to Guptill off Brown on his return to the attack for the 17th over.
Brown struck again in the same over when Jack Burnham (23) picked out Whiteley at deep mid-wicket before Trevaskis (6) was lbw to Parnell.
In reply, the opening pair of Wessels and Guptill made it an afternoon to forget for James Franklin’s side.
