Last year, Gloucestershire were hammered for 230 for four by Sussex at Hove and 213 for two by Worcestershire at New Road - the highest scores of 2012.
Hampshire have beaten Surrey in their last five home encounters.
Leading 2012 wicket-takers Chris Liddle, Mitchell Starc and Reece Topley were all left-armers. Leading run-scorers Phil Hughes and David Miller were also left-handers.
The only tie in last year's competition was between Durham and Lancashire.
