Astros Prospects: MLB Pipeline releases the new Top-30 list.

The prospects who stayed the same.

Rankings from MLB Pipeline.

#1 Francis Martes

#2 Kyle Tucker

#10 Miguelangel Sierra

#21 Brady Rodgers

The constants.

There was little doubt here with the top two Astros prospects were. When Callis joined us on Talking Stros, I joked with him about Tucker needing to be first on the list. Last year, we were saying that A.J. Reed should have been number one over Bregman. A year later, Callis was right, but who would have seen Bregman make the jump he did last year?

Martes threw batting practice yesterday to George Springer and Josh Reddick. According to Brian McTaggart, they both described his stuff as ‘electric.’ Reddick told reporters that he sees the Johnny Cueto comp while Springer offered a Michael Pineda comp. Either way, he will be in the Astros rotation at some point this year.

Tucker has been compared to Ted Williams. While that paints a beautiful picture, we must caution ourselves with his potential. Hinch said that he would like to see Tucker get some at bats this Spring, but says he’s a year away from the MLB.

Rodgers should have moved up the rankings with his performance in Triple-A last year. However, he struggled in his brief stint in 2016 versus big league hitters. Part of his success has come from working with Jeremy Booth with Program 15. His future with the Astros could be decided this year.

Sierra is the first of the many shortstops on this list after being signed by the Astros in the 2014 International signing period. Via MLB Pipeline, he was the most fundamentally sound players available at the time and has grown some power as he matures. He is only 19, so he will take 2-3 more years to be MLB ready.
