The 2014 season has seen a number of notable prospects receive call-ups to the major leagues. With the final month and the corresponding roster expansion approaching, there will be more to come—and soon.

September brings with it 40-man rosters, so Monday should be filled with prospects getting promoted.

During the past week or so, Jorge Soler and Daniel Corcino debuted, among a handful of others.

Soler, as you might’ve heard or seen or read, hit a homer in his very first plate appearance with the Chicago Cubs on Wednesday. Corcino, a right-hander in the Cincinnati Reds’ system, hurled a perfect inning on Aug. 26—which just so happened to be his 24th birthday.

Meanwhile, outfielder Randal Grichuk and reliever Heath Hembree returned to contribute yet again to the St. Louis Cardinals and Boston Red Sox, respectively.

Highly regarded youngsters such as Marcus Stroman, Jonathan Singleton, Oscar Taveras, Ken Giles and Javier Baez have been seeing regular time for their respective clubs for quite some time now. Others, such as Mookie Betts and Taijuan Walker, have been shuttling up and down between the minors and majors for much of the year.

More young impact talent will be joining the mix too. Who will be the next to reach the major leagues? In order to predict estimated times of arrival this season, we’ve classified the prospects on this list using the following color-coded scale:

  • Red: September call-up, at best.
  • Green: Call-up within a week/call-up is imminent.

Here’s a look at the top prospect call-up report for Week 22 of the 2014 MLB season.
