THONGSBRIDGE battler Nathan Sinclair is aiming to topple the No1 seed today and land himself the 18s title at this year’s popular Sellers International.

It’s the last day of competition at Huddersfield Lawn Tennis and Squash Club, where 984 new balls have been used over the past seven days.

All the remaining finals will be held today – the men’s and ladies singles are due on court at 2.45 – and there’s some fantastic action in prospect.

Sinclair – who was beaten by brother and No1 seed Dan in the main singles draw – has been in excellent form in the 18 years and Under section.

And he took part in the match of the tournament so far when defeating Joseph Babbington-Allen to move through.

It took the three hours and 15 minutes to settle the issue after Babbington-Allen took the first set 6-4 and then the second went to a tie-break which Sinclair took 12-10.

Having been taken to the brink, he then won the third set 6-4 and will now play Simon Howson of Sheffield, the No1 pick, in the final.

Howson knocked out Thongsbridge’s Andrew Atkinson, who had got to the semis by knocking out Harry Edwards 7-5 6-1.

In the Boys 14s, No5 seed Ben Kirk is into the final after knockout out No2 Adam Bowen 7-5 6-3.

Kirk will play No1 seed Troy Dixon of Oxfordshire, who went through comfortably 6-2 6-0 against Johnny Carmichael-Plester of Norfolk.

Charlotte Bradshaw of Huddersfield remains on course in the Girls 14s after successive victories against higher-rated players. The 14-year-old from Linthwaite now meets No1 seed Lydia Burrows in the last eight.

Holly Horsfall of Thongsbridge also made the last eight and had a walkover into the semi-finals.

Charlotte Kershaw (Huddersfield) bowed out in the last eight of the Girls 18s when losing 6-2 6-0 to Lancashire’s Natalie Wall, while Yorkshire’s Molly Reed went through after beating No4 seed Louise Holtum 6-1 6-2.

Batley’s Katie Jessop is through to the semi-finals in that section after a 6-0 6-4 win against Yasmina El Sayed and she will play Sarah Kidd of Lancashire, who had a walkover.

In the men’s doubles, Nathan and Dan Sinclair made sure Thongsbridge were represented in the semi-finals, where they will play Paul Jepson and Andrew Lee.

Marsden’s Sean Stafford and Phil Warley (who meet each other in the singles semi-finals) are also through after beating host-club pairing Pete Vann and Stuart Gill. They will now meet Chris Harper and Andrew Westmoreland for a place in the final.

In the ladies doubles, the pairing of Charlotte Kershaw (Huddersfield) and Holly Horsfall (Thongsbridge) are up against No1 seeds Louise Bottomley and Caroline Mount of the home club in the semis.

Kershaw and Horsfall beat Charlotte Bradshaw and Hannah Byram 6-1 6-1 to book their place. Carrie Wagstaff (Batley) and Victoria Cran (Huddersfield) beat Stephanie Carter and Emily Young to reach the semis, where they face Holmfirth duo Susan Brass and Gillian Kilner.
