Abbott re-joined Hampshire on a Kolpak deal ahead of the 2017 season – he previously played for them in 2014 – and has been one of their foreign players since the eligibility rules changed following the UK’s departure from the European Union.
He has taken 278 first-class wickets for them at an average of 19.52 since re-applying, and is the leading wicket taker in Division One of the County Championship this season at 49 at 20.28 each.
“I’m excited to stay with Hampshire for another two years,” said Abbott. “We have a great group of players and since I joined in 2017 I have made some great friendships and memories; I am very proud to call the Ageas Bowl my home.
“We have made some great strides as a team and hopefully we can continue our success in the coming years and get our hands on some more silverware.”
Giles White, Hampshire’s director of cricket, said: “Introducing the right people to the squad is a key element to a successful team and we feel we have struck gold with Kyle. He is one of the most influential foreign players in the game. English game and has a real affinity with the club. We are lucky with him.”
