The way his rehab is progressing, Taijuan Walker could return to the Mariners rotation before June is over.

The 2014 season has seen a number of notable prospects receive call-ups to the major leagues. Undoubtedly, there are more to comeand soon.

In fact, with the Super Two cutoff now in the rear-view mirror, there should be plenty of promotions of prime prospects arriving over the coming days.

Already, highly regarded youngsters like George Springer, Jonathan Singleton and Gregory Polanco are starting for their respective clubs.

Over the past week or so, the injury-riddled Colorado Rockies called up left-hander Tyler Matzek and first baseman/outfielder Kyle Parker, just as the floundering Philadelphia Phillies gave a shot to hard-throwing closer of the future Ken Giles.

The Boston Red Sox brought back third baseman Garin Cecchini, and the Miami Marlins did the same with outfielder Jake Marsnick, who debuted late in the 2013 season, to help cover for the injured Christian Yelich.

It shouldn't be long until other impact talents join the mix as well.

So, who will be the next to reach the major leagues? In order to predict estimated times of arrival in the majors this season, we've classified the prospects on this list using the following scale:

Red: September call-up, at best.

Orange: Second-half call-up.

Yellow: Call-up within a month.

Green: Call-up within a week/call-up is imminent.

Here's a look at the prospect call-up report for Week 12 of the 2014 MLB season.
