They sign 2014 contracts actually. Unless they're older, like Mejia. They may get a taste of EXST over the offseason and its possible if they're advanced enough, they could start out in Arizona. Highly doubtful though. More than one year in the Dominican League for those 2 would be a big disappointment. FWIW, Jimenez and Torres will both show up on BA's top 30. Likely in the late teens to mid 20 range. Parks said he'll consider both for his Cubs top 15. Generally a couple of the top 16-year olds start off in the complex leagues the year after they sign (for example, Baretto is in the GCL this year), but I feel like the Cubs under Theo seem are willing to go slower. Off the top of my head, Larry Suarez, Carlos Zambrano and Felix Pie are the only 16-year olds who signed and jumped to the AZL in their first year in the Cubs system. ETA: Forgot Felix Pie. Has there ever been a team that threw an extremely talented 16 or 17 year old in Single or Double A? Is there any rare talents like that who had great success in the minors at 16, 17..?
