The accolade follows being named Gloucestershire player & bowler of the year, and is further reward for a fine season by the 32-year-old, in which he claimed 64 first-class wickets.
Kirby has performed magnificently for the Shire this season, and led the line wonderfully well with his raw determination providing some memorable spells throughout the season, most notably his 5-44 in the second innings against Kent at Beckenham, when he fought Glos back into the match despite a good batting wicket and unbearably hot conditions.
Steve Kirby is a fantastic character to have on a cricket field, always wears his heart on his sleeve and will hopefully continue to spearhead the attack next season.
