We still don't know when Player X is going to get called up, as injuries and ineffectiveness at the big league levels -- and the constant service-time calculations -- can play a far larger role in these decisions than simply a prospect's performance.

One thing we can get some clues from, however, is the flurry of promotions that come at midseason. Here are 10 players who recently were promoted, and a breakdown of how that affects their path to the majors.

Jackie Bradley, OF, Boston Red Sox
Nobody should have been surprised to see the Red Sox select shortstop Deven Marrero in the first round this year, as they've made a habit of selecting players who entered the spring as a potential top-10 pick but then slipped. Anthony Ranaudo hasn't exactly worked out, but Bradley sure has so far. After showing a line drive bat, outstanding approach and hitting .359/.480/.526 in 67 games at high-Class A Salem, he was moved up to Double-A Portland. A plus defender in center, Bradley is suddenly on pace to reach Boston by next September, if not earlier.
