In 2007 and 2008, Shantry progressed to a mixture of senior cricket at minor counties level with Shropshire County Cricket Club and Second XI cricket for Worcestershire. He took 7/34 for Worcestershire Second XI against Leicestershire II in June 2008,[3] and scored 88 for Shropshire against Wales Minor Counties in August of the same year.[4] Between these two feats, in July, he had appeared for Shropshire in the final of the Resource Bank Twenty20 Cup, which they lost to a star-studded Lashings World XI side despite Shantry's 3/11.[5]
Shantry made his senior debut for Worcestershire in a Pro40 match against Essex at Colchester on 23 August 2009, taking the wicket of Ravi Bopara and not batting.[6] Two days later, he made his maiden appearance in first-class cricket when he was selected for Worcestershire's County Championship clash with Nottinghamshire at New Road. In a drawn game, Shantry claimed the wickets of Bilal Shafayat and Mark Ealham, but was lbw for nought in his only innings.[7] He retained his place in the side in both one-day and four-day cricket, and so his club cricket appearances, now for Walsall, became less frequent.[2]
Shantry pressed his claims for a regular place in the side in his first game of the 2010 season, a non-first-class warm-up match against Bradford/Leeds UCCE. He claimed 5–18 in the first innings, and opened the bowling in the second innings, taking a wicket with the first ball of the innings and finishing with 7–47, to complete a match haul of 12 wickets for 65. Worcestershire went on to win the game.[8]
In September 2014, he scored his maiden first-class century (and took ten wickets in a first-class match for the first time) in a victory over Surrey that guaranteed Worcestershire promotion to Division 1.[9]
In June 2018, Shantry announced his retirement from all cricket with immediate effect, due to ongoing back injuries. In 2022, Shantry became an umpire.[10]
