I like Kepler, but I have to agree. It is a little early to believe that Kepler is a cornerstone. Polanco has hit at every level. His future looks very promising. And Vargas has a .392 OBP in 108 AB. This guy should be getting playing time to see if he can keep his production up to anywhere near what it has been. Sano, Buxton, Berrios. Next level, Polanco, Vargas, Shaggy and ... I would put in a couple more younger pitchers, but I cannot say I know enough about them. Gonslaves, May, Mejia?
