If this all plays out the way the Cubs hope, their collective journey will reflect that of Javier Baez, with failure preceding great success. The middle infielder started terribly in Triple-A this year, but as player development executives will tell you, this is a good thing, really. Because slumps in the big leagues are inevitable when your swing isn't right or you struggle to adjust to how pitchers are adjusting to you, and you have to learn how to dig your way out.

Baez did that at Triple-A Iowa, gradually learning to lay off pitches out of the strike zone, learning that if you ignore the slider in the dirt, it gives you a better chance to get pitches in the zone. This is a message reinforced by the Cubs' new minor league hitting guru Manny Ramirez, who seems to have had an immediate impact on the young players he has worked with and has been impressed with Baez's skills, which have blossomed.

Think of Baez as the college freshman who got a lot of C-minuses in the first marking period but now has graduated from Triple-A with honors: Despite being more than five years younger than the average player in the league, Baez racked up 23 homers and a .510 slugging percentage.
