Top MLB Prospect Call-Up Radar Report, Week 16
JEFFREY PHELPS/Associated Press
Called back up just before the All-Star break, Jimmy Nelson's second start of 2014 didn't go quite as well as his first.

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 brought up infield/outfield prospect Arismendy Alcantara and right-hander Kyle Hendricks not long after trading away starters Jeff Samardzija and Jason Hammel.

Meanwhile, the Milwaukee Brewers decided that Marco Estrada had given up enough home runs as part of their rotation—his 27 homers allowed are by far the most in baseball—so they've turned to their top prospect, Jimmy Nelson. The right-hander's outing just before the All-Star break didn't go all that well, but he should get another start to bounce back.

But as was the case 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 are back in 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 16 of the 2014 MLB season.
