If you are a prospect hound, the past week has made some sort of live baseball package a must for any connoisseur. On Thursday, the Kansas City Royals called up Eric Hosmer, arguably the best hitting prospect at the upper levels. On Saturday, the Atlanta Braves called up Julio Teheran, arguably the best pitching prospect at the upper levels, while the next day the Boston Red Sox promoted shortstop Jose Iglesias, the best defensive shortstop in the minors.
The Teheran and Iglesias promotions require little analysis. Teheran's start against the Phillies on Saturday was the product of a doubleheader and the fact that his turn was up in the Triple-A rotation, while Iglesias is a temporary fill-in for the injured Marco Scutaro and there just to provide late-inning defense and speed off the bench.
Hosmer is a different story. He's not only in Kansas City far earlier than expected; he's presumably here to stay. But was the timing of the move a sound decision by the Royals or something they will regret down the road?
