Worcestershire 298 for 5 (Jones 110*, Libby 77) beat Glamorgan 297 for 7 (Tribe 122*, Hurle 56) by five wickets
A career-best List A score of 110 not out from Rob Jones guided Worcestershire Rapids to an important five-wicket win over Glamorgan which keeps them on track for a quarter-final place in the Metro Bank One Day Cup.
Asa Tribe had earlier batted through Glamorgan's innings for 122 in his side's impressive total of 297 and the visitors looked to be in control early in the reply as they reduced the hosts to 78 for 3.
A staggering fourth-wicket partnership of 172 between Jake Libby (77) and Jones anchored the run chase for Worcestershire, as they swung the momentum back in their favour. Jones hit the winning runs in the 49th over.
Glamorgan's bright start in the sunshine was only blemished by the loss of Eddie Byrom for 41.
Youngster Henry Hurle caught the eye with some expansive shots, scoring 14 off one Ethan Brookes over as the side bottom of Group A passed 100 in the 20th over.
Hurle and Tribe took a liking to a lacklustre Rapids bowling seam attack, as the pair brought up their respective half-centuries in consecutive overs, with Tribe showing his particular disdain towards any short pitched bowling, thrashing the ball through midwicket with frequency.
The second-wicket stand of 104 was ended by Brett D'Oliveira, who bowled Hurle for an impressive 56, as Worcestershire seized the initiative, taking three more wickets for just 26 runs.
Kieran Carlson was the first in a cluster of three wickets to fall, as he succumbed to Ben Allison, before D'Oliveira (2 for 46) picked up his second wicket of an instrumental spell.
Waite's metronomical afternoon with the ball saw him rewarded when Billy Root feathered a full ball behind to Henry Cullen, as the medium-pacer ended his spell shortly after with outstanding figures of 10-2-23-1.
Dan Douthwaite joined the not-out opener, and upped the ante from the get-go, taking Glamorgan beyond the 250 mark, before Tribe notched his maiden List A century with the final ball of the 46th over.
Douthwaite's cameo of 37 from 26 balls was cut short at the death, but Tribe was unbeaten on 122 to see his side finish on an above par 297 for 7.
Despite losing D'Oliveira in the first over, the hosts made an otherwise positive start to the chase, largely due to a composed knock for 19-year-old Dan Lategan, that took Worcestershire past fifty without further damage.
The 17th over of the proved costly however, as the home side lost both set batters - with Carlson taking a stunning one-handed catch at extra cover to remove Kashif for 22, before a catastrophic mix-up involving Jake Libby saw Lategan run-out four short of a maiden List A fifty.
The onus fell on Libby and new man Jones to guide the home side out of their troubling position at 78 for 3, with Glamorgan looking to take advantage of their early wickets.
Both batters shouldered the responsibility in fine style, with Jones returning to form and Libby making his way to a fourth fifty of the competition.
Their 172-run partnership was ended when Andy Gorvin took a fine catch running back over his head to dismiss Libby for 77, with the departing skipper's side still requiring 48 from the final six overs.
Jones brought up a sensational 101-ball hundred with the chase nearing its climax, but even the departure of Ethan Brookes in the dying stages did not deter the home side, as Cullen batted through with Jones to see the Rapids to a crucial five-wicket victory.
