Tom Haines took three wickets for just five runs, but it was his leadership that truly shaped Sussex's commanding performance at Hove. With England's regular captain Ollie Robinson away on international duty, Haines guided his side to an innings-and-98-run victory over Glamorgan in three days, propelling Sussex to the top of County Championship Division One with their fourth win in seven matches.

The match hinged on a single dramatic moment: the over just before lunch on day three. Glamorgan had resumed with hope, trailing by 324 runs but buoyed by memories of a miraculous rescue here three years earlier when they scored 737 in their second innings. Openers Zain-ul-Hassan and Asa Tribe batted with determined resistance, accumulating runs methodically. But when Haines turned to spinner James Coles ten minutes before the interval, the tide turned instantly. Coles dismissed ul-Hassan on his second delivery, and three overs later, Carson bowled Tribe as the last ball before lunch fell—a sequence that deflated Glamorgan's resolve before they could build momentum.

The afternoon session became a story of narrowing possibilities. Kellaway struck seven fours in his 55, while Glamorgan's batsmen showed grit, reaching 212 for three at tea. They had almost stabilized. But Sussex's bowlers were relentless. From the first ball after tea, Haines found Colin Ingram's edge, and within four overs, three more wickets tumbled. Kiran Carlson was run out by Goodman at square-leg; Sean Dickson was caught at second slip. The momentum had irreversibly shifted.

James Coles, who had smashed 224 not out on day two to anchor Sussex's first-innings total of 521, claimed crucial second-innings wickets including Chris Cooke, lbw in a partnership that had promised brief resistance. Dom Goodman, drafted in from below the squad to replace the England-bound Henry Crocombe, marked his debut with two catches behind the stumps in a single over. When Coles bowled last man Ryan Hadley, the match was over, Sussex's attack having overwhelmed Glamorgan's batting across the three days.

Tom Hughes contributed 72 runs and Haines himself scored 48, but it was Sussex's bowling depth—seam and spin perfectly balanced—that proved decisive. Glamorgan head coach Richard Dawson acknowledged the shortfall with candor: his team had scored isolated fifties but failed to construct the kind of big partnerships that had defined their victories elsewhere this season. "We know that," he said, accepting that inconsistency had cost them. "When we've won games this season we've put together big partnerships and did it consistently. But we haven't done that this week."

Haines, reflecting on the win, praised his squad's collective effort even when individual contributions seemed modest. "It was a team performance," he noted, highlighting how Jaydev Unadkat bowled 20 overs of high-quality cricket without taking a second-innings wicket—a measure of his value without the reward of figures. With an extra day's rest before Hampshire arrives at the end of the week, Sussex's bowlers can recover and look ahead. For now, they sit atop the division, their depth and balance having overcome a visiting side that came to Hove determined but left frustrated.
