Souza, Treinen, and maybe Barrett would be useful-now call-ups. Maybe Tyler Moore, also, since LaRoche has a stiff back. Souza can replace an outfielder...Werth needs a rest now and then, and Span has played a lot, as well. If Barrett has corrected the balk motion, maybe we'll see less and less of Blevins.
All good, and just at the right time.
