We also have Greg Jones, Eddys Leonard, Freddy Zamora and Ethan Murray to account for.
Of the 2003-2004 birthday men being considered for AAA (Burke, Pratt, Adams, Lara), I assume Pratt (120 career AA games, potential first AAA game at age 21.62 years) is the most likely to be rostered there, following the Turang career path (73 career AA games, first AAA game at age 20.70 years).
I agree that the Burke vs. Adams placement decision looms large, but maybe we'll give Adams some more opportunities at third base to retain the flexibility to keep them both in AA to start the season.
