Northamptonshire Captain Will Young hit a superb ninth List A century but Worcestershire hauled in the chase in a DLS affected contest at Wantage Road.
Azhar Ali did most of the work for the visitors, the Pakistan veteran defying a hamstring injury mid innings to post 131 with 17 fours and one six.
He shared an enterprising partnership worth 138 with rookie Taylor Cornall who made the second half-century of his brief career to date. While Azhar fell with 29 runs still needed, Worcestershire crossed the DLS impacted line with four balls and six wickets to spare.
For Northamptonshire, skipper Will Young struck a battling unbeaten 104 from 94 balls (6 fours, three sixes) in bowler friendly conditions to help his side post a competitive 248 for four despite two lengthy interruptions for rain which reduced the game to 39 overs a side. Young was watchful early in his innings against the seaming ball and reached the boundary just twice in his first 50 runs. He kept the scoreboard ticking though, bringing up his half-century from 72 balls, before putting his foot down and reaching three figures with two legside sixes in the final over of the innings.
Earlier, put into bat under under gloomy skies, Northamptonshire lost Emilio Gay lbw to Ben Gibbon and had advanced to 44 for one when the first break for rain came.
When they came back, Ricardo Vasconcelos soon started to locate the boundary, scoring the lion’s share of an 84-run stand with Young. He smashed Dillon Pennington down the ground and played a sweetly timed late cut behind square off Joe Leach, but advanced to his half-century in less emphatic style, thanks to four overthrows. He looked well set for another big score after his century last week, playing a gorgeous on-drive off Ed Barnard and lifting the same bowler over the infield.
But Vasconcelos’ knock of 70 (80 balls, 10 fours) ended soon afterwards when Adam Finch got one to jag back sharply and hit the top of the stumps. Worcestershire collected their third wicket in the next over thanks to a brilliant direct hit from the deep courtesy of Gibbon which accounted for Saif Zaib and left Northamptonshire on 108 for three.
Young punched Leach down to backward point early in his innings, but did not locate the ropes again until he had reached 40. As he accelerated, he hit over mid-on and brought out the scoop shot in a partnership worth 114 with keeper Lewis McManus.
McManus swung high over square leg for six to bring up the century partnership off 86 balls in the penultimate over. He dispatched Pennington’s next two balls for four to reach his half-century from 47 balls before holing out in the deep.
That left Young to finish the innings in style with a four and two maximums off the final over. The blaze of boundaries saw 42 runs coming off the final 12 balls.
A few eyebrows were raised around the ground as the DLS method added just 5 runs to the Worcestershire chase, despite the major interruptions to Northamptonshire’s innings.
Brandon Glover made two crucial breakthroughs accounting first for Cornall who tamely chipped to mid-on after 83 balls at the crease. In Glover’s next over Gareth Roderick fell scooping as McManus ran backwards and took the catch to leave Worcestershire on 157 for two.
That was to be the last breakthrough for some time as Azhar and Libby shared a stand of 68. Azhar had to call Roderick back as a runner after suffering a hamstring injury, but unleashed a string of boundaries, pulling and cutting before clipping off his toes to bring up his century from just 78 deliveries.
The pair saw off a typically tight spell from Ben Sanderson, but with six runs an over needed off the final six, Azhar finally fell when he pulled Jack White to Vasconcelos who took a superb tumbling catch in the deep.
Barnard skied a catch off the final over off White, but with only one run required, it was scant late consolation for Northamptonshire who were left to rue the calculations and what might have been on a different day.
