England Saxons duo Noah Cato and Adam Powell are among 11 Saracens players to extend their contracts at Vicarage Road..
Fellow backs Neil de Kock, Kameli Ratuvou, Rodd Penney, Chris Wyles and James Short have also committed to the Guinness Premiership club, along with forwards Hayden Smith, Mouritz Botha, Justin Melck and Rhys Gill.
Wing Cato, 21, revealed he had not hesitated in pledging his loyalty to the club, who are just a point off Guinness Premiership leaders Leicester.
"It was an easy decision for me and I'm really excited about what is happening at Saracens," Cato told the club's official website.
"We're moving forward every day and not only is it great to be part of that, but to be able to share that with a fantastic group of players who are also my friends is something special."
Centre Powell, 24, added: "I've grown up at Saracens and this is my club so I'm delighted to have signed a new deal.
"We're really set up for an exciting second half of the season."
Former Bedford second row Botha is hoping that his performances for Saracens can him go on to follow Cato and Powell in the Saxons set-up.
Botha, who was born in South Africa but now qualifies for England, said: "It was a big step up from the Championship to the Premiership this season but things have gone really well for me and I want to keep pushing that bar even higher with Saracens and maybe even pushing for a place in the Saxons squad."
