The explosive 22 year-old fast bowler, who can bowl in excess of 90mph, arrives at The BrightonandHoveJobs.com County Ground after a number of counties had been chasing his signature.
Mills, who toured Sri Lanka earlier this year with England Lions, began his career with Minor Counties side Suffolk before moving on to Essex, for whom he made his first-class debut in 2011. In the same season he also featured in the England setup for the Under-19s and the Development XI.
In his 59 first-team matches for Essex he has taken 76 wickets and will be aiming to fulfil his exciting potential which has seen him called up to the Lions squads over the past three years.
He will remain at Hove until at least the end of the 2016 season and said of his move, “I’m really pleased to be on board. As soon as Sussex came in for me, I knew it was a county that I wanted to join. I’m really glad it is all finalised.
“The injuries look to be behind me now and I’m really looking forward to moving down here, getting stuck in this winter and going strong next year.”
Sussex’s Professional Cricket Manager Mark Robinson said, “We’re hugely excited by the arrival of Tymal. He’s a player of enormous potential who is blessed with great pace and a true fast bowler’s frame, and we can’t wait to see him bowl next season.”
