Picking prospects who are on the verge of "breaking out" is such a tricky thing.
Last year, Brandon Belt failed to make the Giants' list of top 30 prospects according to Baseball America. He ended the season as the team's top prospect, came into 2011 with the same status, and just a few days ago earned his first start on Opening Day, starting at first base.
Not too many people pegged him as a breakout star of 2010, and why would anyone have? Belt was a solid hitter at Texas, but flashed nowhere near the potential he fulfilled last season.
Likewise, there were few "experts" that could have envisioned the kind of bounce-back, breakout season that New York farmhand Andrew Brackman had. A year after posting a 2-12 record, a 5.91 ERA and 76 walks in 107 innings, the Yankee fireballer pitched to a 3.01 ERA in Double-A, posted a 126-to-39 K-to-BB ratio for the season and positioned himself for a big-league call-up as early as this season.
Like I said, it's a tricky game.
Keep that in mind as I present my top 30 candidates to break out this season—one from each team—with players from every level, ranging from Triple-A to the Gulf Coast League to the DSL.
