There's nothing quite like April in Major League Baseball. Truth, for now, is in the eye of the beholder and mind of the believer. That's especially true when it comes to rookie performers who qualified for 25-man rosters out of spring training.
Without a track record of major league performance to fall back on, fans, broadcasters and analysts have a very small sample size to use when dissecting young players. Although minor league numbers and prospect rankings can be instructive in determining true value in each respective rookie class, day-to-day results have a way of fooling observers.
The season is young, but a slew of rookies have burst onto the scene across the sport. While no one can take away game-changing plays, impact innings or dazzling efforts posted thus far, we can project forward to separate these players.
Which rookies should you buy into performing well all summer? Which will soon become footnotes over the course of a long season?
Here's how the top performers in the current rookie class stand up in Bleacher Report's "buy or sell" exercise.
