Surrey head coach Gareth Batty has stepped down to join Indian Premier League side Chennai Super Kings as an assistant coach.

Batty led Surrey to three consecutive County Championship titles in his first three seasons in charge and twice guided them to T20 Finals Day.

"Thank you hardly seems enough for all that Surrey has meant to me," the former England spinner told the club's website.

"The new journey is a very exciting one for my family and I, and I'm looking forward to getting going."

Batty's departure ends a 21-year association with Surrey.

He had two spells as a player, the first from 1998 to 2001 after leaving Yorkshire. He then spent seven seasons at Worcestershire before returning to The Oval in 2010.

Batty was club captain between 2015 and 2017, and in total played more than 350 times for Surrey, taking more than 500 wickets across all formats.

Batty, who played nine Tests for England, retired in 2021 and immediately joined Surrey's coaching staff.

After he was appointed head coach in 2022, Surrey became the first team in nearly 60 years to win three County Championship titles in a row.

"It is difficult to put into words just how much Gareth Batty has given to Surrey County Cricket Club, both as a player and as head coach," director of cricket Alec Stewart said.

"I have known and worked with Gareth for many years and throughout that time he has shown an outstanding commitment to this club.

"While we are sorry to see him go, I understand that this opportunity was too good for him to pass up on and will enable him to spend more time with his family outside of the IPL season."
