Top MLB Prospect Call-Up Radar Report, Week 15

As Andrew Heaney proved, not every prospect is a success in his first taste of the major leagues.

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

Highly regarded youngsters like George Springer, C.J. Cron, Marcus Stroman, Jonathan Singleton and Gregory Polanco have been starting for their respective clubs for quite some time now. Others like Oscar Taveras, Taijuan Walker and Kevin Gausman (no longer prospect eligible) have been shuttling up and down between the minors and majors.

With less than a month to go until the trade deadline, there should be plenty of promotions of prime prospects once the wheeling and dealing opens up 25-man roster spots. That's just what's starting to happen with the rebuilding Chicago Cubs, who announced Wednesday they've brought up infield/outfield prospect Arismendy Alcantara.

Also on Wednesday the Boston Red Sox decided to designate veteran backstop A.J. Pierzynski for assignment, according to Gordon Edes of ESPN Boston. They'll be turning the job over to prospect Christian Vazquez, a stellar defensive catcher who can handle the bat.

As we saw with Andrew Heaney of the Miami Marlins and Domingo Santana of the Houston Astros, not every call-up works out right away. Heaney, a 23-year-old left-hander, went 0-3 with a 6.53 ERA in his first four big league starts. Meanwhile Santana, a 21-year-old outfielder, went 0-for-13 with 11 strikeouts in his initial four games. Both received return tickets to Triple-A to work on some things.

Regardless, they could be back in the bigs soon enough and more impact young talent will join the mix. 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.
  • 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 15 of the 2014 MLB season.
