Yes this is just the list of guys 21 years old or younger that were called up this year. (Its not like people have just started the Jenkins, Culpepper request to have them up since the deadline, it seems to have been a recurring theme for a while now, No?) Teams have called up players like Jenkins and Culpepper and given them a chance for as long as I have been watching baseball, Some at the beginning of the year, some in the middle and some in end, but sure lets move the goal post to teams don't do it at this time of the year, and ignore that 11 players similar to Jenkins have debuted in the majors this year, and dozens of guys Culpepper's age have a well.
Didn't Cleveland call up Angel Genao today, he is a 22 year old SS (younger than Culpepper),
