Sussex newcomer Aaron Thomason scored a superb 90 on his first class debut to secure a draw.

He frustrated Worcestershire’s last-day push for victory in the drawn Specsavers County Championship match at Kidderminster.

Thomason, signed this week after being let go by Warwickshire, came to the wicket with Sussex on 314-8 20 minutes before lunch – a lead of 186 and still nearly 70 overs remaining.

But he batted with great authority and shepherded last man Abidine Sakande in adding 82 for the final wicket to take the game away from the home side.

It was a record tenth-wicket partnership for Sussex in matches against Worcestershire.

Thomason, who played only white ball cricket during his spell at Edgbaston, was eventually last out – bowled by Brett D’Oliveira – after hitting four sixes and 11 fours in his 115 ball knock.

He kept the strike so effectively that Sakande, who ended on five not out, faced just 26 balls during a stand spanning 18.5 overs.

The outcome might have been so different had Worcestershire keeper Ben Cox been able to hold onto a difficult chance away to his left offered by Thomason when on two off Ed Barnard.

Worcestershire were left a target of 297 in 40 overs and lost the wickets of Josh Dell (15) and Callum Ferguson (13) in reaching 82-2 before the two sides shook hands with Daryl Mitchell unbeaten on 34.

Sussex had resumed on 236-5 and Worcestershire made encouraging early progress.

Laurie Evans added only seven more runs to his overnight 106 after Sussex resumed on 236-5 before he edged Ross Whiteley through to keeper Ben Cox.

It ended a partnership of 61 with David Weise.

The second new ball became due after 13 overs and brought two further breakthroughs.

Worcestershire club captain Joe Leach struck in his second over when Wiese (47) was trapped lbw.

The 300 came up in the 97th over before Chris Jordan (8) also became an lbw victim to Ed Barnard at 314-8.

At that juncture it all pointed towards a potential Worcestershire victory and a further scalp came just after the resumption when Ollie Robinson (23) cut a short ball from Whiteley to backward point.

But Thomason had other ideas and, with the support of Sakande, ensured that an early finish was the likely outcome.
