The disappointing performance of the Twins prospects made me curious to see how the Twins compared with other teams in bringing good players to the majors. The quickest way to do this comparison was to look at the number of players receiving votes for Rookie of the Year since 2000 by team and to see, on average, what percentage of the votes they received. I then created a product of the two to power rank the teams.
Guess where the Twins finished. For those of you with short attention spans, they are last. They have produced the worst assemblage of rookies in the major leagues since 2000 according to Rookie of the Year voters. (The list of those Twins rookies receiving Rookie of the Year Votes since the year 2000 is at the bottom.)
You can't claim market-size bias on this information as the team at the top of the list is the Tampa Bay Rays. It just simply looks like the Twins do not bring players up to the majors who are ready - or all that good - and this has been the case for the entirety of the 21st century.
