An established member of the Durham bowling attack, Australian seamer Thorp qualifies as a non-overseas player through his British parents.
Having signed in 2005, he has consistently been among the county’s leading bowlers and can also contribute lower-order runs.
Thorp played a prominent role in 2008, claiming 50 County Championship wickets to help Durham finish top of the 18-team pile for the first time.
He saved his best until last with 7-88 at Canterbury in Kent’s second innings as the north-east side, on the last day of the summer, sealed a 71-run victory which ultimately earned them the title.
Another solid showing in 2009 proved his credentials as a key member of Durham's squad. He finished with 30 wickets - including two five-wicket hauls - as the club regained their championship crown.
Injury curtailed much of his season next time out, but he once again proved his worth over the next two seasons by getting back among the wickets - efforts that earned Thorp a new one-year deal in 2012.
