Tom Haines ended the first day 105 not out in Sussex’s first innings 239 for 3 against Surrey at The Kia Oval.
It was the 21-year-old Haines’ second first-class hundred and he featured in century stands with both Aaron Thomason and Delray Rawlins as Sussex made an impressive start to the final round of Bob Willis Trophy fixtures after winning the toss and opting for first use of a slow-paced pitch.
Rawlins made a punchy 65 from 88 balls, launching both Moriarty and Scott Borthwick’s leg spin for straight sixes, while Thomason’s 49 in an unfamiliar opening role was another important contribution to the Sussex cause.
At stumps Haines had faced 216 balls, hitting 14 fours and batting with great self-discipline throughout a day of only five hours’ playing time, because of a 12 noon start following Surrey’s floodlit Vitality Blast fixture against Middlesex on the ground the previous evening.
Surrey’s bowlers had little to encourage them in the conditions, with 52 overs of spin employed by Rory Burns, but the sluggish surface did not prevent Overton, who had looked fairly innocuous in a new ball spell of 4-0-20-0 on his red-ball Surrey debut, from peppering both Haines and Rawlins in a five-over late afternoon burst that was markedly more hostile.
Haines had initially been joined in a determined first wicket stand of 102 by Thomason, who fought his way through 115 balls after being promoted to open following Phil Salt’s call-up into England’s white-ball squad.
But soon after Moriarty had Thomason leg-before in the 33rd over, pushing crookedly forward, Sussex also lost Harry Finch for 1 when off spinner Amar Virdi won a deserved lbw verdict during a skilful 11-over afternoon spell costing just 22 runs.
Rawlins had just hit Moriarty for his first six, followed by one of his eventual six fours, when non-striker Haines and the bowler exchanged words and the match was held up while Neil Bainton and Ben Debenham, the umpires, spoke to both players and Surrey captain Burns.
Overton, who then replaced Moriarty for the 45th over with Sussex on 134 for 2, almost immediately hit Haines on the grille of his helmet and then Rawlins on the body as he worked up some real pace from around the wicket to the two left-handers.
But Rawlins responded with a gorgeous off drive for four and Haines also pulled Overton, who has left Somerset in search of regular red-ball cricket with Surrey, to the ropes in the best passage of cricket of the day.
Virdi, though, emerged as Surrey’s most successful bowler of the day, returning after tea to have Rawlins caught by Will Jacks at short leg after a partnership with Haines of 116 in 30 overs.
