I know we've talked before about the difficulty of moving relievers up during the season. There are good guys up in Pawtucket, and many relievers don't have true upside, so it's better to have a strong bullpen than push them forward mid-season. However, with a guy like Bayer, who is recently drafted, would the Sox hope for some upside, and test it in a higher level this year? If he were to move up, I'd rather see him jump to Salem, where the bats would be more advanced, rather than merely move to Greenville, where the competition is similar at this point in the summer to the NYPL. Also, I'd of course want to see a little more out of him before being considered for a promotion.
