Pakistan's Azhar Ali made an unbeaten double century as he helped Worcestershire rewrite the record books in an English County Championship match against Leicestershire on Friday. Azhar and former England Under-19 international Jack Haynes put on 281 for the third wicket -- a record partnership against Leicestershire, surpassing the 278 by Cyril Walters and Harold Gibbons in 1934. Their stand was the cornerstone of Worcestershire's 456 for three, a lead of 308, at stumps on the second day of four at New Road.
