MLB Prospect Power Rankings: Top 10 On The Cusp Of Reaching The Majors (April 26, 2017)

by Eric Stashin (aka The Rotoprofessor)

Which prospects are on the verge of making an impact in the Major Leagues? This weekly column will rank the ten who are closest (as well as other names that are being closely considered). Keep in mind that while talent is factored in opportunity plays a major role, so there may be some “lesser” prospects who rank fairly highly on the list (please note all stats are through Monday and the number in parenthesis is the ranking from last week):


1) Amed Rosario – New York Mets – Shortstop (NR)
Among the best prospects in the game, Rosario made his first start at third base on April 21.  That shows the concern the Mets have for both their slow start and the production (or lack thereof) from Jose Reyes.  The team is banged up and in desperate need of a spark, something Rosario could provide.  While the Mets don’t want to rush him and risk stunting his growth, they also can’t afford to see their season end in April.

For his part Rosario is tearing up the Pacific Coast League, hitting .414 with 8 RBI, 8 R and 5 SB.  He’s not going to be a source of power, at least not yet, but with 8 K over 70 AB he knows how to handle the bat and can help to set the table/score runs hitting ahead of Yoenis Cespedes and company.  Watch where he plays closely, as it could indicate how close he is to arriving.


2) Austin Meadows – Pittsburgh Pirates – Outfielder (4)
While he’s hitting .200 on the season, it hasn’t been strikeout issues (15 K over 60 AB, with just 6 K over his past 39 AB) and that’s a promising sign that things should turn around.  Meadows doesn’t bring one specific skill to the table, but the sum of the parts will certainly hold value as he profiles as a 10/15 player with a solid average (he’s a minor league career .295 hitter).  With Starling Marte lost to suspension and Adam Frazier now on the DL, the Pirates may no longer be able to remain patient and wait for the Super 2 deadline.  How long can they really lean on Jose Osuna and John Jaso in LF?  Something has to give, and that could quickly prove to be Meadows.


3) Yoan Moncada – Chicago White Sox – Second Baseman (5)
With Tyler Saladino struggling to get going the White Sox have reason to consider promoting Moncada sooner than expected.  Of course Moncada has had his issues while playing at Triple-A:

  • Strikeouts – 30.9%
  • Extra Base Hits – 1 Double, 4 Home Runs

The home runs are nice, but where are all the extra base hits?  Can he ever get the strikeouts under control (13 K in past 37 AB)?  When you look and see him hitting .300 it’s easy to think that he’s ready, but there are questions to be answered.


4) Bradley Zimmer – Cleveland Indians – Outfielder (1)
Lonnie Chisenhall and Austin Jackson have been performing, giving the Indians some short-term relief to their struggling outfield.  Neither of them are likely long-term solutions, but they will give Zimmer time to work out his obvious flaws (16 K over his past 34 AB).  He brings an intriguing blend of power and speed and there is no question that he is going to arrive and should make an impact.  Just know that with the good will come the bad (a poor average thanks to the significant swing and miss to his game).


5) Franklin Barreto – Oakland A’s – Shortstop (3)
As soon as Marcus Semien got injured the thought was that the A’s could push Barreto to fill the void.  That hasn’t been the case, at least not yet, and while there are financial reasons to keep him down there also are performance based ones.  As we noted on Monday (click here for the article) he’s struggled with strikeouts, lacks elite power and there are questions about how his speed will translate.  Don’t get us wrong as there is significant upside/value, but he’s also not a can’t miss option upon his arrival (and the team has reasons to be conservative).


6) Rhys Hoskins – Philadelphia Phillies – First Baseman (NR)
Tommy Joseph was one of the reasons the team was willing to move on from Ryan Howard (though he didn’t help his own cause).  At the same time Joseph, who was a popular “breakout” candidate heading into the season, has fallen completely flat (.200/.250/.291 slash).  Could the Phillies look to make a change before long?

Hoskins is doing what he can to force the issue, hitting .321 with 4 HR over 53 AB at Triple-A.  Perhaps more impressive is his 11 K vs. 9 BB, as that is answering the biggest question that had been facing him (21.2% strikeout rate at Double-A last season).  The ’17 success is in a short sample, but he’s showing the power was for real (38 HR in ’16) and if he can continue making consistent contact it won’t be long before he arrives.  (Note: You could argue the team is in a similar position with Cameron Rupp/Jorge Alfaro, but considering the defensive importance we’d expect Rupp to have a little bit more rope.  That’s another situation to monitor, though.)


7) Ryan O’Hearn – Kansas City Royals – First Baseman (NR)
Kansas City spent to import Brandon Moss this offseason and over the first few weeks he’s been a complete flop (.146 with 2 HR).  That’s the most likely opening for O’Hearn, even though Eric Hosmer has also struggled (.192 with 1 HR).  The team has shown it’s willingness to change things up, recently demoting Raul Mondesi, and O’Hearn is stating his case for a promotion with six multi-hit games in his past seven (overall he’s hitting .333 with 5 HR).  Even more impressive is that he has just 2 K over this stretch, which was always the biggest question facing him.  It’s a small sample and likely will prove to be an aberration, but with the way he’s hitting he may not be long for the Majors.


8) Reynaldo Lopez – Chicago White Sox – Starting Pitcher (8)
Whether it will be Reynaldo Lopez or Lucas Giolito who first gets an opportunity when a need arises in Chicago’s rotation can be much debated.  The fact is it will likely come down to whose turn fits into the rotation best, as neither are impressing early on at Triple-A.  They both have significant upside, but they need to start showing it.  Once they do they will fly up the rankings, but for now we are going to have to wait for their arrival.  While Lopez remains the name listed here, consider it a shared spot.


9) Nick Pivetta – Philadelphia Phillies – Starting Pitcher (NR)
He’s already primed to take the spot of Aaron Nola, who was recently placed on the DL, but yesterday’s rain out keeps him down in the minors for another few days (and therefore keeps him eligible for this list).  In his three starts at Triple-A Pivetta has been tremendous, with 24 K vs. 2 BB over 19.0 IP.  That’s a significant step forward for a player who owns a minor league career 7.5 K/9 and 3.1 BB/9.  It’s fair to wonder if the inflated numbers are nothing more than a small sample aberration.  Throw in his career 1.00 GO/AO, which indicates potential home run issues, and there are significant risks.  Still, small sample or not, his start to the year makes him an intriguing potential option.


10) Dinelson Lamet – San Diego Padres – Starting Pitcher (NR)
He has opened eyes over his past two starts, racking up 22 K over 12.1 IP at Triple-A.  Of course he also a 9.5 K/9 across three levels in ’16, with a 3.7 BB/9 and 0.88 GO/AO being the biggest questions.  His control is still a question (9 BB over 20.0 IP), though it’s not a terrible number and he’s generating an extreme amount of groundballs (1.67 GO/AO).  You put that package in San Diego, and you get an intriguing pitching prospect who could arrive in short order given the questions in San Diego’s rotation.


Honorable Mention – Brandon Woodruff – Milwaukee Brewers – Starting Pitcher (NR)
Woodruff isn’t the Brewers’ best pitching prospect (those honors go to Josh Hader), but it’s easy to envision Woodruff being the first callup.  He’s only allowed runs in one of his four starts at Triple-A, posting a 1.61 ERA and 0.99 WHIP over 22.1 IP.  He hasn’t shown significant strikeout stuff (17), but he has strong control (6 BB).  He has shown more strikeout upside in the past (9.82 K/9 over 113.2 IP at Double-A in ’16) and also more groundball stuff (1.09 GO/AO this season, 1.19 in ’16).  We obviously need to have some reservations, with the strikeouts struggling thus far, but the upside and opportunity (Milwaukee starters own the fourth worst ERA in the league) are there.

  1. Steve says:

    Really like the inclusion of Rhys Hoskins this time around… there is a real lack of youth at the 1B position across the league and it feels as though the position is just waiting for the next few young stars to break in at the position. He could be one of them.

    I think Hoskins will get the call this year, he is 24 years old, so you can’t keep him down much longer or you will eat into his prime. 14.3% BB with 17.5% K at AAA in 17 games excellent even for a small sample. His walk rate has improved at every level every year, and his strikeout rate has gone north of 20% only once (AA last year).

    The question to me that will have a big impact on him this year is when does he get the call? Considering the Phillies org, I would be stunned if they called him before Super 2. But once Super 2 timeframe hits I’d say it’s fair game.

    Bellinger and Hoskins could be the youth wave at 1B that the position needs.

    • Rotoprofessor says:

      I agree with you on having to wait until Super 2, but you never know. Don’t forget to add Vogelbach into the youth infusion as well

  2. David says:

    Sweet Lou Brinson not even in the top 10?? He’s a top 5 talent, 5 tool player, and tearing up the minors.

    • Rotoprofessor says:

      He is, but the Brewers do have a lot of outfielders and they are going to give Domingo Santana and Keon Broxton a chance to get right. Brinson will be on this list before long

  3. HH says:

    What about Derek Fisher OF Hou? Their OF is a little banged up and could use his power speed combo.

    • Rotoprofessor says:

      I highly considered putting him on there actually, but the fact that they haven’t added him yet tells me they aren’t rushing to. He may make the cut next week

  4. bartonrp says:

    How about Daniel Palka (Twins)? Only Eddie Rosario or Kennys Vargas stand in his way….

    • Rotoprofessor says:

      palka seems to be getting his strikeouts under control, which is the big key. If he can maintain it he will find himself on the list in short order, but it won’t be a long stay because he’ll be in the big leagues

  5. Oddball Herrera says:

    Personally, I think Baez’ leash in Chicago is a lot shorter than people assume. People are sleeping on Happ because of his cruddy BABIP but I think he’s up earlier than Brinson, Meadows Barreto etc because, like with the Dodgers and Helpings, wins mean more to the Cubs this season than economic efficiency, super 2 less of an issue for the big budget teams

    • Rotoprofessor says:

      That’s fair, and if there was an obvious fit for playing time I’d fully buy into Happ getting promoted sooner rather than later. Just hard to see where the AB come from right now with Zobrist/Baez/Russell on the roster. In a few weeks, if everyone is still struggling, the thought of a promotion will be that much greater.
