Sanchez just finished his year 25 season in AAA.
He has shown little to no power, but a decent average.
Has a low on-base percentage and minimal slugging.
Unless the Sox have a multitude of utility injuries or just flat out rebuild, I don't see him sticking in the majors.
He just doesn't have what it takes offensively to stay long on a 26-man roster.
Lenyn Sosa and Romy Gonzalez probably have better shots.
