Surrey 189 for 9 (Jacks 86, Harmer 3-44) triumphed over Essex 176 for 8 (Rossington 78, Jordan 3-34) by 13 runs.
Will Jacks smashed five sixes in an electrifying 86 to solidify Surrey's lead in the Vitality Blast South Group, ensuring a home match in the quarter-finals. Jacks' 46-ball innings, featuring five sixes, included a pivotal 63-run partnership with Jordan Clark over five overs, setting a record for the sixth wicket against Essex. This recovery was crucial after Surrey experienced a mid-innings slump, ultimately posting 189 for 9 and winning by 13 runs.
Surrey's innings faced challenges from Essex's spin duo, Matt Critchley, who claimed 2 for 22, and Simon Harmer, who achieved his season's best with 3 for 44. Paul Walter contributed by taking two late wickets, ending with 2 for 26 and increasing his season tally to 15.
Adam Rossington's valiant effort to secure Essex’s third win in four days and advance to the knockout stages fell short. Rossington scored a 49-ball 78, including five sixes, but his dismissal dashed Essex's hopes. Essex now needs at least a point from their final match against Hampshire on Friday to reach the quarter-finals.
Chasing a target of 190, Essex lost Dean Elgar in the third over when he hit Clark to cover point. However, Rossington and Michael Pepper quickly accelerated, with both batsmen lofting Sam Curran for sixes in one over to square leg, reaching fifty inside five overs.
Pepper, having scored a century at Hove just 24 hours earlier, surpassed 500 runs in this season’s Blast upon reaching 12. Unfortunately, he added only 15 more before skying Cameron Steel to short extra cover. Steel struck again shortly after, bowling Charlie Allison with a delivery that stayed low.
Steel intensified the pressure on Essex by conceding only seven runs in his first two overs, before Rossington hit him for a six over long-on after reaching a 33-ball fifty.
Clark got lucky with a full-toss that Walter sent skyward, allowing Rory Burns ample time to catch in front of the stumps. Critchley soon followed, lifting Chris Jordan to deep midwicket.
As Jordan and Curran restricted Essex to single-figure overs, the required run rate climbed to 15 with 47 runs needed from the final three overs. The target became unattainable when Rossington was dismissed in the 18th over, hitting Curran to the mid-off boundary.
Surrey, batting first on a used wicket, initially progressed smoothly, reaching 62 at the end of the power play with the loss of Dom Sibley, who was lbw to Shane Snater. However, their momentum was disrupted when Critchley and Harmer took three wickets in eight balls, halting their mid-innings runs.
Laurie Evans was bowled by a turning delivery from Critchley, while Harmer dismissed Burns and Curran on consecutive balls. Burns was clean-bowled outside his bat, and Curran misjudged his first ball and was lbw.
Jamie Overton displayed aggression, hitting a six off Luc Benkenstein over midwicket and another boundary past the bowler. Yet, he soon picked out Eathan Bosch on the long-off boundary, giving Critchley his second wicket.
Throughout, Jacks steadily accumulated runs. He had already hit Harmer for a huge six, launched another off Snater, and reached his half-century with a straight six off the Essex captain. Jacks added two more sixes off consecutive balls from Harmer but was caught on the boundary attempting a third, at cow corner. His sixth-wicket partnership with Clark was pivotal in getting Surrey back on track.
After Jacks' departure, wickets fell rapidly as Clark, Jordan, and Tom Lawes were all caught in the deep.
