We are busy getting ready for book shipping day here, so I'm going to go the discussion question route for a few days to keep you guys busy. Next week we'll get back into a normal rhythm.

Today's question is about lefty prospects Martin Perez of Texas and Christian Friedrich of Colorado. I rated them both as Grade A- prospects in the book. Perez is younger and has a better physical upside, but Friedrich is no slouch, is more polished, and put up excellent numbers last year.

Disregarding the effects of pitching in Texas and Colorado, who would you rather have?
