Trinder, 22, is in midfield alongside Matt Banahan (Bath Rugby) and Charlie Hodgson (Sale Sharks) in an experienced back line that also includes British and Irish Lions wing Ugo Monye (Harlequins).
Number eight Luke Narraway leads the side and is one of four full internationals in a young pack with hooker David Paice (London Irish), prop Paul Doran-Jones and lock David Attwood (both Gloucester Rugby).
The replacements include Newcastle Falcons scrum half Micky Young and London Irish flanker Jamie Gibson, drafted into the squad this week following injuries to the Northampton Saints pair of Lee Dickson (shoulder) and Calum Clark (back).
The side is coached by Stuart Lancaster, assisted by Jon Callard and Simon Hardy, and will form the core of the England Saxons squad defending the Churchill Cup next month.
Head coach Lancaster said: "It's a very exciting line-up with a good blend of experience and youth and we have the opportunity to measure ourselves against a very experienced Barbarians side including some of the very best players in the world on Sunday.
"It is a young England side and the match day squad has an average age of 23, but these are players who've been in terrific form for their clubs and many of them have played a major part in big games at the end of the season in the Aviva Premiership and in Europe."
