Despite his young age, Sorrell has already been at the club for an amazing eight years.
Since breaking into the first team back in 1998, he has been a regular and has made the position his own in the last few seasons. His professionalism both on and off the pitch led him to being made a vice-captain this season and coach Wayne Shelford has no hesitation in stating that Sorrell "is a key figure in the Saracens team".
A firm crowd favourite for his hard working attitude, last summer Sorrell was rewarded for his hard work and talent by being selected in The England touring squad for the USA and has more recently been included in this summer's 70-man England training squad.
"I'm delighted that we have secured the services of Kevin," commented coach 'Buck' Shelford. "His commitment to the club gives us solidity and he's now a key figure in the squad both on and off the pitch.
"He proved to everyone what a consistent contribution he makes to the side after returning from a very serious injury to play a major role in Saturday's game. He turned over Bath possession several times in midfield and despite not having the match-fitness, hit the ground running from start to finish and showed why he deserves his call up to the 70-man England training squad."
Since joining Saracens from Campion School in Essex, Sorrell has had a very good upbringing. Playing and training alongside the likes of Steve Ravenscroft, Philippe Sella and Tim Horan, he has constantly grown as a player and now represents a solid all-round performer in the midfield.
Sorrell is currently the fourth most-capped Saracens player in the squad, with 147 appearances, behind Kyran Bracken (148), Kris Chesney (163) and the ever-present Richard Hill (226).
"I'm very pleased to have signed a new deal with the club," said Sorrell ahead of Saracens' crunch game with Bristol on Tuesday night.
"I've been at the club for quite a while now and I'm looking forward to helping the club to make progress over the next few years.
"Obviously it's been a difficult season, but I feel that Saracens have a bright future and that the ambitions of the players, coaches, staff and fans can be realised."
