Jones finished with his best one-day figures which left the Hawks firmly anchored to the foot of the south/west division table.

The Royals, facing a victory target of 210, stormed to their second successive win with a massive 22.3 overs to spare thanks to a dazzling opening partnership worth 160 in 19 overs between Vikram Solanki and Steve Davies.

Skipper Solanki led the way with a hard-hitting 81 while Davies added to the Hawks' agony by blazing to an undefeated 76.

Earlier, the visitors, after winning the toss, had found Jones a lively handful, particularly when he picked up his last four wickets in 11 balls for just five runs.

It easily eclipsed his previous best limited-over return of three for 19 for his former county Glamorgan against Lancashire in 2005.

Hampshire batsman Greg Lamb, who top scored with 84 including eight fours off 89 balls, was included in Jones' impressive haul which saw him finish with figures of 10-1-32-5 and restricted the visitors to 209 in 48 overs.

Worcestershire never had any trouble overtaking the Hawks total thanks to Solanki and Davies.

Both completed their half centuries off 38 balls with Solanki looking destined for a deserved ton until he holed out to Dawson at long-off off Taylor after chalking up two sixes and 12 fours off 59 balls.

Davies, who finished off the job with Moeen Ali (42 not out), cracked 12 fours off 71 deliveries.
