Yorkshire players celebrate a wicket during the win against Hampshire Rothesay County Championship, Division One, Utilita Bowl, Southampton (day four)

Hampshire 197 & 238: Albert 57, Bess 5-103

Yorkshire (19 pts) beat Hampshire (3pts) by 39 runs

Dom Bess delivered his first five-wicket haul of the season to hand Yorkshire a crucial victory in their nail-biting County Championship relegation battle with Hampshire. Stand-in captain Bess returned 5-103 to break Hampshire's resolve and give Yorkshire a 33-point lead over their rivals for the drop at the bottom of a congested Division One. Toby Albert's half century (57) had given his side hope of chasing 278, but they fell 39 runs short to put Hampshire in deep trouble of falling into the second tier for the first time since 2014.

The match encapsulated an incredibly tight Championship season – where six teams could still be considered in the title race and as many as seven teams are in or could get dragged into the relegation fight. Momentum had swung either way throughout the four days on a hard, dry pitch, which had both got truer for batting, but also taken more spin.

The match path had led to 172 runs still being required by Hampshire at the start of day four, with seven wickets in hand. Difficult scoring conditions meant the win was always likely to go to the side with more patience and it was Yorkshire who eventually proved decisive in the battle of endurance.

Tom Prest did not display the requisite qualities as he advanced and whipped Bess straight to mid-on to the 25th ball of the day. But Albert and Ben Brown did for over an hour. The duo showed doggedness to keep their wickets while slowly chipping away at the runs. Albert was rewarded with his fifth Championship half-century, and first since April last year, in a gritty 138 deliveries.

It appeared Hampshire had found the blueprint to grind the match in their favour, but the pressure was always there and Yorkshire's tight bowling and smart fields allowed Bess to make inroads. Bess, who was captaining with Jonny Bairstow off the field with a hand injury, had positioned a leg slip for Brown. He then floated a back of a length, which turned, caught the glove of the pulling batter and landed easily in Will Luxton's grasp.

For Albert, a deep backward point was positioned far behind square and well off the ropes. Bess' straight delivery was swept firmly straight to the fielding trap. Yorkshire had felt wronged by an obstructing the field appeal on the first day; they were further incensed with the umpires after Neal got away with edging to first slip on the cusp of lunch.

Bess drew an outside edge out of the batter and on first viewing, it appeared that the ball had bounced to George Hill at first slip. But a replay clearly showed that it had deflected off substitute wicketkeeper Fin Bean's foot rather than the ground. Their anger had subsided somewhat within 20 minutes of the interval when Jafer Chohan's half-tracker found Felix Organ's leading edge and looped up to mid on.

Neal had scored a maiden professional century in the One-Day Cup match on this pitch two weeks ago; he was now the main thorn in Yorkshire's route to victory. He batted stoically for two hours, scoring 39, but failed to keep a slog sweep down and was caught on the deep mid-wicket boundary.

There were still 43 runs needed for Nos. nine, ten, and eleven to score, but they could only combine for three of them as Kyle Abbott was lbw to give Bess his fifth wicket. Lyth rounded off the well-fought victory by bowling Eddie Jack to give Yorkshire victory in the sort of match that demonstrates why the County Championship remains, at its best, compelling.

Hampshire captain Ben Brown: "I thought we could have chased it but to be honest our batting hasn't been good enough all season. We've had an honest chat in the dressing room about not getting those top order runs, which makes it difficult to win games. You are always scrapping to catch up with the games when you aren't making those impacts. We came into the week 17 points adrift and it is 19 now. A lot of teams have beaten each other. There are still five matches to go - roughly a third of the season - it is not a time for anyone to give up or lose hope. We are flat because this was a massive opportunity with Yorkshire being around us in the table, but you can't lose hope. We need to get on a roll and go bang-bang to shoot us up to mid-table."

Yorkshire head coach Anthony McGrath: "It would have been a travesty if we hadn't have won that game. We've created about 14, 15 chances today. Credit to Hampshire, they've scrapped really well, but the effort the boys put in. Anyone who's been here for four days has seen how much we've fought. Anything can happen with five games left, so it was important to start this block with a win. We've been knocked down quite a few times, but the signs are good, as I keep saying."
