According to BRef, Kepler is actually younger for the FSL than he was for the Midwest League. And presuming he moves to New Britain next year, he'll go from 1.3 years too young in A last year, to 1.6 years too young for A+ this year, to 3.7 years too young for AA next year. I agree with you though, in the big picture, Kepler's still a work in progress, and his translation to a better power output can't be truly determined from one year in the FSL, and he's had a career characterized by fits and starts. And only playing in 61 games last year in Cedar Rapids hasn't helped his progression any, either. Yet the Twins are still showing faith in him by again sending him to the AFL. Clearly, staying healthy and continuing to show signs at the plate- like the ones he's shown since July 13- are going to be critical for Kepler in 2015- for the Twins to continue to show their confidence in his prospect status. Before this recent run, I gave him quite a bit less than a 50-50 shot that he can ever become a contributing major league starter. As of now, this latest run has been encouraging enough that I think he's now closer to 50-50 at becoming a contributing platoon starter, who in that role can potentially give you low-double digit HR and an OPS+ in the 120s. Hopefully, something clicks this fall and next spring and he raises the odds of reaching his full potential
