Jake Arrieta

The 2014 Chicago Cubs broke camp in Mesa, Ariz. this week with several unanswered questions in regard to their final 25-man roster. There are several position battles which will involve players who are on the cusp of making the major league squad. 

Which players currently on the roster bubble are going to have a tough time making the team?

Let's take a few moments to examine the players that project to be locks to make the team. 

Finding a bunch of players on the verge of a "breakout" season isn't necessarily all that hard. Finding a bunch of almost universally-undrafted players who are on the verge of a "breakout" season? That's a little tougher.

Anyone can make a case for the Rays' Matt Moore, the Cubs' Anthony Rizzo or the Mets' Matt Harvey, all young promising players ready to take the step from good to great as breakout candidates in 2013. But each of them were selected in every draft out there, often in the middle rounds.

Baltimore Orioles starting pitcher Jake Arrieta has thrown just one good game over the course of the last month and a week.

Considering that Arrieta was the Orioles' Opening Day starter, and that the young man was supposed to step up and take on the role of being the club's ace this year, that's pretty pathetic.

Josh Hamilton hit for the "cycle" Tuesday night against the Baltimore Orioles. But when the ball flies out of the park, they don't let you stop at first, second or third.

Hamilton hit four two-run home runs against the shell-shocked Orioles. He finished a perfect five-for-five with eight RBIs.  He now sits at 14 homers on the year with 36 RBI and appears to be steam-rolling toward another MVP award.
