The transition from the minors to the big leagues is not an easy transition for most players. Even first-round draft picks sometime have difficulty taking their game to the next level. The jump in talent is just that significant.
This year, quite a few rookies have made their way onto big league rosters. Quite a few have adjusted seamlessly, while others have stumbled a little bit.
Rookies in today's game are nurtured. Pitchers have innings limits and hitters are put into roles where they can succeed.
This is done either to preserve their abilities and not burden them with a massive workload, or to keep their confidence high during inevitable slumps.
These young studs will either bud into a superstar or wilt under the pressure. Only time will tell.
