Surrey 525 (Burns 161, Sudharsan 105, Patel 77, Jacks 59, Farhan 7-140) and 177 for 9 dec (Burns 71, Patterson-White 5-96, Farhan 3-77) drew with Nottinghamshire 405 (McCann 154, Hameed 68, Haynes 68, Verreyne 50*, Jacks 7-129) and 121 for 0 (Hameed 61*, Slater 56*)

Surrey saw their romp towards a third consecutive Division One title lose a little momentum as they were forced to settle for a draw against relegation-threatened Nottinghamshire in the Vitality County Championship at Trent Bridge.

The result means that Surrey's lead of 35 points at the start of this round of matches, after winning seven of their previous eight matches, is cut to 24 thanks to Somerset's victory over Durham at Taunton.

At the other end of the table, after Warwickshire and Worcestershire both won, the points taken for the draw - a merit worthy achievement after trailing by 120 on first innings - leaves Nottinghamshire 10 points ahead of Lancashire in the battle to avoid being relegated alongside Kent. All sides have three matches to come.

Rory Burns made 71 to go with his first-innings 161 with Liam Patterson-White finishing with five for 94 before the declaration came, but the Nottinghamshire left-arm spinner's achievement was again upstaged by his young team-mate Ahmed, with whom he shared all 53 overs of the Surrey second innings.

Already in the record books on his Championship debut as the youngest player to bag five wickets or more in a first-class match in Britain, he achieved another mark of distinction, arguably even more prestigious, when he claimed Jordan Clark as his 10th wicket of the match.

This enabled him to replace Grace as the youngest to take 10 or more wickets in a first-class match in Britain - in fact anywhere other than in South Asia.

Grace returned the extraordinary match figures of 13 for 84 - on his first-class debut - for Gentlemen of the South against Players of the South at the Oval in June 1865, at the age of 16 years 340 days.

With a match analysis of 10 for 247 at the age of 16 years and 192 days, Ahmed lowers the record by 148 days. He bowled a staggering 76.4 overs in the match, which may be a record in itself for a debut appearance.

Surrey, who had missed out on a fourth first-innings batting point that seemed theirs for the taking, arguably made another mistake when they declared just shy of an hour after lunch.

The timing meant Nottinghamshire would have to score at more than six runs per over to win the contest on a pitch that had yielded at barely three-and-a-half all game, with the Kookaburra ball reportedly hard to get away on a slow surface.

Surrey were banking on England off-spinner Will Jacks, who had matched Ahmed by taking seven first-innings wickets, and leg-spinner Cam Steel to exploit the fourth-day pitch but Hameed and Slater were rarely troubled as neither could find a way through.

Earlier, Surrey had advanced from 13 for one overnight to 104 for four by lunch, playing in light for that period so gloomy that bowling spin was the only option for Nottinghamshire skipper Hameed.

A second-wicket stand worth 57 was broken by Patterson-White, who induced a miscue to short midwicket by Ryan Patel, following up by turning one sharply to bowl Will Jacks three balls later.

Patterson-White had Burns dropped at square leg on 39, after which the Surrey captain's stop-start dithering over a single into the offside off Ahmed saw new partner Ben Foakes run out by Hameed's throw to 'keeper Kyle Verreynne.

As the tempo increased after lunch, with Surrey now chasing runs for the declaration, Ahmed completed his 10 for the match by bowling Burns and having Clark caught behind in a botched scoop attempt.

Patterson-White raised his five for the innings by having Sai Sudharsan caught at deep midwicket and bowling Conor McKerr and Tom Lawes, for his pains getting clubbed for two meaty sixes by Dan Worrall before Burns signalled the declaration.
