Perez, 24, has seen very brief playing time at the major league level in each of the last four seasons. In 647 Triple-A plate appearances, he slashed .280/.321/.387 while adding 21 stolen bases. The Venezuelan native has split his time as a professionally evenly between shortstop and second base.
Meanwhile, the 30-year-old Herrera has delivered a career .249/.304/.343 slash line in 470 turns at bat in the majors, all compiled in sporadic action over 2012-15. He is a true utility player, having spent time at all three outfield spots and every infield position left of first base. Herrera has had some success at the plate at the Triple-A level, where he owns a .307/.375/.431 batting line in just over 1,000 plate appearances.
