Jordan Garrett re-wrote the county age group record books with an unbeaten double century for Oxfordshire Under 17s against Bucks in the ECB Championship.

The Great & Little Tew batsman, 15, smashed an astounding 208 not out to help Oxfordshire to a four-wicket win on first innings at Aston Rowant, as they closed in on the Division 2B title.

The only previous double century-maker for Oxon Under 17s was James Cook with 200 not out more than a decade ago – against the same opposition.

But Garrett’s knock was arguably more of an achievement playing two years above his own age group.

Bucks won the toss and elected to bat before rattling up a formidable 375-8 dec in 86 overs.

Garrett and fellow Under 15 opener George Reid set up a platform on day two with 166 for the first wicket.

Reid eventually departed for 73, while Garrett continued in imperious fashion towards his maiden Oxfordshire century.

When he passed three figures, the youngster then proceeded to double that with a chanceless second hundred, his knock containing 31 fours and one six.

Oxon reached 379-6 with more than ten overs of the second day remaining in a remarkable run chase.
