Tom Alsop has joined Sussex on a full-time basis after impressing in the first two months of a season-long loan from Hampshire.
Alsop, the wicketkeeper-batter and former England Lions player, has averaged 31.30 in the early stages of the County Championship season, including a hundred against Middlesex, and hit 65 off 30 balls on his T20 debut for the club against Kent last week.
"To sign permanently for Sussex is great news," Alsop said. "I've thoroughly enjoyed my time with Sussex and I'm glad that I have made a decent start to the season in both formats of the game.
"I'd like to thank Hampshire and I'd like to say a massive thank you to the coaching staff at Sussex for believing in me and to everybody else who has made me feel at home so quickly."
Alsop was a product of Hampshire's pathway system and played 146 games for them across formats, with his innings of 72 in the 2018 Royal London Cup final - which Hampshire won - among his best moments for the club.
His form as a young player earned him England Lions call-ups in 2016-17, and Giles White, Hampshire's director of cricket, said he had made "a significant contribution across all formats".
Sussex said in a statement that Alsop had signed a two-year permanent deal which will become active upon the completion of his loan deal in November.
