Well, looking over the last decade or so these players debuted at these ages w/Twins: 20 - Rivas 21 - Ortiz, AJ, Hunter, Guzman, Santana, Adam Johnson, Mauer, Liriano, Casilla, 22 - Milton, Radke, Lohse, Rincon, Cuddy, Morneau, Kubel, Durbin, Crain, Garza, Gomez, Revere, Ramos, Hendriks, Arcia 23 - Mays, Romero, Restovich, Baker, Perkins, Slowey, Benson, Parmelee, Hicks 24 - Dougie Baseball, LeCroy, Jones, Kielty, Bartlett, Boof, Span, Plouffe, Pinto 25 - Koskie, Guerrier, Neshek, Blackburn, Valencia, Waldrop, Swarzak, Gibson 26 - Buchanan, Ford, Duensing This obviously isn't everyone - no need to look at Morales or Miller but it's a decent list. Not sure age tells us much. Obviously, the better players got up faster, which isn't surprising. (I think everyone except Hendriks and Casilla in the 22 or younger groups had been ranked in the top 100 at some time). I tend to think that the Twins are more willing than other teams to let "old" prospects contribute. (In the 24 and older group only Gibson - who had TJ surgery - was ranked by baseball america, I believe). It looks like the Twins have tended to get the franchise type players and the first division complementary players get their feet wet by 22 and hope to establish them within two years of that. I guess I'm just not sure that the Twins have been holding elite talent back. I know some people thought Cuddy should've been a regular before 05/06 and injuries held back guys like Kubel and Gibson and some guys struggled after being called up (Hunter, AJ, Johnson).
