Guerra.

After two seasons and 168 innings split between two-leagues in the Mets system, Deolis Guerra had compiled a decent peripheral set -  averaging  7.3 strikeouts per nine innings while walking 3.6 per nine.  Once with the Twins organization, the team assigned him to Fort Myers (HA) where, at 19 years old, Guerra was nearly three years younger than his competition last year.  In 2008, his third stint in the Florida State League, word trickled in that his fastball had lost a few MPHs and his control vanished.  In what was his worst month, Guerra threw 23 innings in August and issued 20 free passes.  Not surprisingly, his overall walk rate ballooned (4.9 BB/9) while his strikeout rate shrank (4.9).  Reports of Guerra's reduced velocity and sub-par peripheral numbers conjured up collective groans from Twins territory as the budding pitching prospect acquired for Johan Santana trade seemed like it it was heading for another prospect miss.   ...
