Top MLB Prospect Call-Up Radar Report, Week 19

After a surprising call-up to the Cubs on Tuesday, Javier Baez hit the game-winning homer in his first big league game.

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 (currently on the disabled list), Marcus Stroman, Jonathan Singleton, Gregory Polanco and Ken Giles have been seeing regular time for their respective clubs for quite some time now. Others, like Oscar Taveras, Taijuan Walker and Kevin Gausman, have been shuttling up and down between the minors and majors for much of the year.

With the July 31 trade deadline now in the rearview mirror, there should be plenty of promotions of prime prospects after the wheeling and dealing opened up 25-man roster spots on teams that are selling and building for the future.

That's just what happened in Chicago, where the Cubs somewhat surprisingly brought up top infield prospect Javier Baez Tuesday, then watched him smack the game-winning home run in extra innings at Coors Field.

It was a busy week of prospect promotions overall, as the likes of James Paxton (Seattle Mariners), Kennys Vargas (Minnesota Twins), Mike Foltynewicz and Domingo Santana (Houston Astros), and Mookie Betts, Anthony Ranaudo and Heath Hembree (Boston Red Sox) all either made their big league debuts or came back up.

Meanwhile, contenders are finding ways to fit youngsters into the mix to help down the stretch. That's the story in Seattle, where the Mariners popped Chris Taylor in late July. The 23-year-old shortstop is getting a chance to prove he can be better than incumbent Brad Miller, who struggled all year in his first full season in the bigs.

Not every call-up works out right away, though, as was the case with the aforementioned Santana. A 21-year-old outfielder with the Astros, Santana went 0-for-13 with 11 strikeouts in his initial four games back in early July and was promptly demoted. He worked on some things down in Triple-A, and he's back up—for now.

More young impact talent will join 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.
  • Yellow: Call-up within a month.
  • Green: Call-up within a week/call-up is imminent.

Here's a look at the top prospect call-up report for Week 19 of the 2014 MLB season.
