The Stash 6/9: The Top 10 Hitting Prospects to Stash

Brennen Gorman looks ahead, detailing the top 10 hitting prospects to stash in 2019.

Every weekend, I post about the minor leaguers you should be stashing on your team. These rankings are done solely for prospects with the potential to impact the 2019 season. Their ranks are predicated on when they will be called up and raw talent—we want to give you an edge in building your team throughout the year. Prospects are a great way to stay ahead of the curve once the most notable prospects are called up. Not all prospects need to be stashed in every league, as not all league compositions are made equally.


1. Yordan Alvarez, OF/DH, (Houston Astros) – ETA Mid June


After going a season-high nine games without a home run, Yordan Alvarez came back with a vengeance, mashing three home runs over his last five games. Alvarez has hit 23 on the season with a .343 batting average in Triple-A ball. His Super Two deadline may have passed, or it will soon pass, at which point Houston will have little rationale to keep Alvarez down any longer. He is the best player in the minor leagues and should be universally stashed.
Authors Note: Yordan Alvarez was called up—go get him, y’all.


2. Kyle Tucker, OF, (Houston Astros) – ETA Late July


As of writing this, Kyle Tucker only played four games this week, but also hit four home runs this week—adding on two stolen bases as well. He now has 20 home runs on the season and is well on his way to 20 stolen bases (currently with 14). Tucker has been elite for the past month now and unlike Yordan Alvarez is already on the team’s 40-man roster (having played in Houston late last season). Despite injuries on the major league club, even to those playing his natural position in left field, Tucker has not received the call, making it difficult to project when the team will finally pull the trigger. Regardless, Tucker has reached a point where he has been too hot to not stash in deeper leagues.


3. Luis Urias, 2B, (San Diego Padres) – ETA Mid June


Luis Urias will be on his way back to the major league soon; San Diego GM A.J. Preller was quoted by the San Diego Union-Tribune as saying “I think he’s on a really fast track… we just wanted to… make sure that he was in a good spot, so that when he came back and hit (against) the better quality big-league pitching, we felt like he was in a really balanced position and in a powerful position.” Urias has slashed .370/.472/.647 since May 1 with seven home runs and four stolen bases. While the power might not last, Urias has built a case for himself as a high floor bat that can chip in across the board.


4. Carter Kieboom, 2B/SS, (Washington Nationals) – ETA Mid July


Carter Kieboom remains stone cold, batting .192 over his past 15 games with a sole home run and no stolen bases. With Brian Dozier raising his batting average high enough to at least start flirting with the Mendoza line, Kieboom is unlikely to see a promotion soon. Washington is not likely to compete this year, so the team has little reason to rush Kieboom. His long term prospects are still phenomenal, but in the short term, it will be a waiting game.


5. Bo Bichette, SS, (Toronto Blue Jays) – ETA Late June


Bo Bichette finally began his rehab assignment on Friday, after spending the last seven weeks on the Injured List on a projection that initially called for four to six weeks. Toronto has been all-in on calling up their young talent this year and Bichette would be the last big name Toronto has to call up this season. Toronto could manipulate Bichette’s service time as they did with Vlad Guerrero Jr. given Bichette has missed most of this season and is considered to be one of baseball’s top prospects, but with Toronto shifting Lourdes Gurriel Jr. to the outfield, the team seems to be clearing the way for Bichette now.


6. Jorge Mateo, SS/2B, (Oakland Athletics) – ETA Early July


Jorge Mateo continues to roll on, grabbing another home run and a stolen base while batting .320 this past week. Mateo is on a 14-game hitting streak that includes eight multi-hit games.  Mateo is incredibly aggressive, leading to a paltry 4.3% walk rate, but has maintained his 5% strikeout reduction from last season, leading to a spike in his OBP. Jurickson Profar is batting .192 this season at second base in Oakland; Mateo would be an upgrade both over Profar at second base and over Marcus Semien as the team’s leadoff hitter. Mateo has little left to do in the minor leagues as this is his second full season in Triple-A and has managed to only improve his second time around.


7. Ryan Mountcastle, 1B/SS/3B, (Baltimore Orioles) – ETA Late July


Impressively, Ryan Mountcastle mashed three home runs last Sunday and continues to hit well with a .313 batting average-to-date. His aggressive approach and walk rate is a red flag to sustained success, as his 3.1% walk rate drives a rather average .335 OBP. Mountcastle is a bat-first prospect and has been shifted around the infield as the team tries to figure out a landing spot for him in the Majors.


8. Jake Rogers, C, (Detroit Tigers) – ETA Late July


Jake Rogers has gone cold over his past seven games, batting .120 without a home run or extra base hit. Rogers is still operating on a small sample size in Triple-A after decimating Double-A and earning a promotion in late May. Unless Rogers picks it up over the next few weeks, a prospective mid-summer call-up will quickly become a September call-up.


9. Ian Miller, OF, (Seattle Mariners) – ETA Early June


Mitch Haniger ruptured his testicle on Friday and will be on the Injured List indefinitely for now. Ian Miller has been rock solid in Triple-A this season and plays Haniger’s natural right field position. Miller is slashing .296/.348/.505 this season with six home runs and 16 stolen bases. His strikeout and walk rates are excellent (18.9% and 7.9% respectively). Seattle could do much worse than having Miller fill in for Haniger while he recovers (God Bless).


10. Yadiel Hernandez, OF, (Washington Nationals) – ETA Late July


Yadiel Hernandez has undoubtedly been one of the best—and certainly one of the more overlooked—bats in the minor leagues. He is slashing .368/.455/.698 with 16 home runs and five stolen bases, capped off by a 14% walk rate to a 16.9% strikeout rate. Hernandez is 31 years old, so his dynasty prospects are not as high as his redraft potential, but with Washington set to implode around the trade deadline, Hernandez could be getting his chance soon.

A lifetime Tigers fan (oh boy) getting ready to watch some good minor league baseball for the next few years. Liquor lawyer by trade, consumed by baseball statistics for pleasure? Yep. Seems about right.

      • Brennen Gorman says:

        Yeah – I’ll add a note to the article, he got called up after I had submitted the article to my editor. I think he will do fantastic – irrespective of the fact he is on Houston, I am aggressively pursuing him in any league I do not already have him.

  2. Greg says:

    Why isn’t hiura on here?

  3. Jack says:

    For Tucker, isn’t Super 2 the determiner as to when he gets the call? Figure 15-20 games from now?

    • Brennen Gorman says:

      Could be tomorrow, could be September. Since he started heating up, there is no reason to keep him down other than the success and contracts of his MLB compatriots.

  4. Lassetjus says:

    Would have thought Keston Hiura would have made this list.

  5. Chucky says:

    Is Luis Robert too far down the food chain to be listed?

    • Brennen Gorman says:

      I think so, September at the earliest and given we’re three months out, I do not advocate stashing players that far out as the bench space in most leagues is too valuable a tool in the interim.

  6. Swfcdan says:

    Bad year so making some moves to improve my farm hopefully getting Soroka (yipee!) and Xavier Edwards. Like those guys?

    Drop contenders are (need 2 obv), can you rank by droppingness:
    Corey Ray
    Daz Cameron
    Tristan Lutz
    Luis Rengifo

    Also will Zack Collins ever get the call? Improved his slug .100 this year and still got good potential in OBP leagues. Have heard his D has improved too.

  7. Swfcdan says:

    Also received another offer. You prefer Kieboom or B McKay moving forward? Both close and both great prospects, just depend on needs?
