Development comes at its own pace, not the schedule you need, so it’s important not to rush prospects just because they are talented, shiny, or could help your big league team be more competitive sooner.
It’s also far from an exact science, since some prospects jump from AA to the big leagues, others find AAA to be a big step from AA, some are ready to thrive in the big leagues at age 22 while others need to marinate until their mid-20s before making that sudden leap.
The A’s would love their best prospects to get to Oakland sooner rather than later, with the “Matt clock” ticking — Chapman and Olson are in their first of 6 years of contract control, meaning they will not likely share too many charter flights with the likes of Austin Beck and Lazaro Armenteros.
