The number one prospect in all of Major League Baseball injured his left thumb last week during play in the Arizona Fall League. Red Sox farmhand Yoan Moncada did not suffer any broken bones, but he will miss at least a couple of games before retuning to the lineup. The 21-year old Cuban had a left hand injury last year in the Instruction league as well. The Red Sox are hoping that the AFL action will restore Moncada's confidence after a dismal—strikeout-laden—end to his 2016 major league stint (which started out hot).
