The Stash 05/11: The Top 10 Pitching Prospects to Stash

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

Every weekend I will be posting about the minor leaguers that you should be stashing on your team. These rankings are done solely for prospects who could potentially impact the 2019 season. Their ranks are predicated on when they will be called up and raw talentwe want to give you an edge in building your team throughout the year. Not all prospects need to be stashed in every league as not all league compositions are made equally.


1. Zac Gallen, SP Miami Marlins – ETA Late May


Another week of play, another week of dominance for Zac Gallen who now sports a 1.14 ERA and a 55:8 K:BB ratio over 47.1 innings. Opposing hitters are hitting a paltry .121 and is averaging just under 3 hits per game. Gallen has the lowest ERA, most innings pitched, and most strikeouts of any pitcher with at least 20 innings under their belt this season. While his .153 BABIP and 93.8% Left-On-Base rate will both regress, Gallen has become a must-stash as he continues to force Miami’s hand to call him up as Sandy Alcantara and Trevor Rogers continue to struggle.


2. Jesus Luzardo, SP Oakland Athletics – ETA Late June


Little has come out about Jesus Luzardo’s progression over the past two weeks, but given his initial 4-6 week timeline has now come and gone, the question remains when he will start his rehab in the minors. He will need to build his arm back up after a serious shoulder injury and should spend at least a month in the minors before Oakland would consider a call-up. In the spring he threw a 0.93 ERA and 15 strikeouts over 9.3 innings. Until there is more information, stand pat.


3. Dylan Cease, SP Chicago White Sox – ETA Mid July


Dylan Cease struck out five batters in his sole game this week but was pulled after 4.1 innings after it took him 84 pitches (57 strikes) to do so. He let up four hits and three walks over that span, although letting up only 1 run. Cease is unlikely to be called up any time soon, with the best estimate being after his Super Two date in July.


4. Mitch Keller, SP Pittsburgh Pirates – ETA Mid July


Mitch Keller labored through his sole start of the week, throwing 83 pitches (only 47 strikes) over only 3 innings, where he also walked four and struck out 4. Poor control continues to erode Keller’s season, since arriving in Triple-A last season, Keller has had a double-digit walk percentage and frequently struggles to go deeper into games because of his pitch count. He strikes out batters at an elite rate (11.57 K/9 this season) but has been unable to find sustained success in Triple-A.


5. A.J. Puk, SP Oakland Athletics – ETA Late July


A.J. Puk began throwing to hitters in Extended Spring Training this past week, starting his road to recovery from Tommy John surgery that will take a lengthy rehab, about a month, before Oakland would consider a call-up. As Puk has never thrown above Double-A ball, where he has only 64 innings under his belt, Oakland might be even more patient with Puk’s return.


6. Forrest Whitley, SP Houston Astros – ETA Mid July


While Forrest Whitley’s obscene 7 home runs in 18.1 innings is likely contributing to his ballooned 10.80 ERA (backed up by a 4.9 BB/9 rate and a 47.4% left-on-base rate), the short term concern is about Whitley’s use in 2019 is Houston using bullpen outings to manage his workload. It is increasingly likely that Whitley will not get a role in the majors until late in the season and that, if he did earn a role in 2019, it would be in the bullpen. Whitley’s future is still one of high whiffs (11.78 K/9 despite the above), which will keep him on radars despite his early struggles.


7. Brendan McKay, SP Tampa Bay Rays – ETA Late July


Tit-for-Tat, Brendan McKay has been one of the best pitchers in Double-A so far this season (alongside Matt Manning). McKay sports a 1.82 ERA and 47 strikeouts over 29.2 innings. While his ability to be a two-way player never came to fruition, as a pitcher McKay is lights out. Tampa Bay has moved McKay rapidly through their system, his longest stint in any given level was 9 starts (in 11 games) in High-A last year. If McKay keeps this up he should ascend to the Majors sometime this season.


8. Austin Voth, SP Washington Nationals – ETA Early June


Austin Voth has had a seemingly uninteresting season so far this year, but a 28.9 K%, a .390 BABIP, and a 2.73 FIP paint a picture of a pitcher that has been dominant on the mound with a large degree of bad luck. In 29.2 innings, Voth has only walked 7 batters to 37 strikeouts. Washington has a need for new blood with Anibal Sanchez and Jeremey Hellickson both better in some other capacity. Voth has made slow adjustments over the past few seasons and is looking more like a fantasy-worthy starter than ever before.


9. Logan Allen, SP San Diego Padres – ETA Late June


Removing Logan Allen’s first two starts of the year (where he let up 12 runs in 5 innings)we get a pitcher with a 2.19 ERA and 27 strikeouts over 24.2 innings. This line still accounting for a 3 home run game that netted him 4 earned runs in only 1.2 innings. Allen has been either dominant or wildly inconsistent, but worthy of a place in San Diego. Cal Quantrill has had two acceptable games in San Diego and as a whole, the team’s rotation has performed well so far. There is no clear path for Allen at the moment, but will be on the tip of the team’s tongue should the need arise.


10. Rico Garcia, SP Colorado Rockies – ETA Late July


Aside from Matt Manning and Brendan McKay, there has been no better pitcher than Rico Garcia. Breaking out so far this season (and doing so at age-25), Garcia has a 1.71 ERA and 42 strikeouts over 31.2 innings. A healthy 53.1% groundball rate is a particular highlight given his home park will be Coors Field.  While some regression will be headed Garcia’s way, Colorado has a profound need for starting pitching with German Marquez the only starting pitcher with a sub-4.00 ERA and Jon Gray the team’s only sub-5.00 ERA starting pitcher.

    Would you drop Stripling for Gallen in a 14-team H2H points league? I’ve been holding Stripling since he lost his rotation spot.

    • Chucky says:

      Interesting. I like Stripling over Gallen if for no other reason, you know someone in that rotation is going down. Gallen isn’t even on the 40 man roster. But that’s a book keeping technicality. Interesting dilemma.

  2. Bruce says:

    Is there news on Triston McKenzie’s return and status? Assuming he pitches well when he plays, is he a reasonable candidate to make this top 10, or has he dropped too far because of the injuries and time missed?

    • Brennen Gorman says:

      He started throwing on flat ground this past week, still no clear timetable for a return. I do not see me including him on the list this year, even were he to return and get promoted in September (which I am skeptical about) – I would imagine it would be in relief.

  3. Jim says:

    Part of Keller’s control issues I believe are him incorporating a new pitch to his arsenal and he’s getting a feel for it.

    • Brennen Gorman says:

      In some outings, maybe, but in his most recent he only threw it 7 times – could be a mental thing, but it is not used enough to justify his ball count.

  4. D says:

    Drop josh James for Gallen at this point? Just not sure he would get the call over Whitley if something happened opens up? Separate question, would it be silly to stash Nate Pearson and drop Jesus Sanchez now—Pearson has #1 upside? I already have Soto, Robles, Haniger and Rosario manning the OF (this is a dynasty where we can keep NA prospects)

    • Brennen Gorman says:

      I would – at this point James would need to be stretched out to do a spot start and Houston called up Corbin Martin to fill the open roster spot with Collin McHugh going to the bullpen. I do have a batter bias when it comes to filling a dynasty bench, but I do not think that would be a bad swap.

  5. Josh says:

    Why did Thorpe drop out? Less likely of a call-up, or did he bomb since the last list?

    • Brennen Gorman says:

      He bombed in a big way, to a degree given his other struggles this season make it far less likely to get a call any time soon. Had toyed with keeping him on the list at 10, but I would rather add him back after a few solid starts.

  6. Brett says:

    Drop Josh James for Corbin Martin?

  7. Sam says:

    Hey Brennan!

    Would you drop Luiz Gohara on a prospect roster for Zac Gallen?

    Love the website and all the content you guys put out!

  8. Rance says:

    Just recently found this list. Had already been sitting on Cease and Luzardo. Wasn’t even aware of Gallen. Good article though, 4 years into a dynasty league will keep it on my favorites tab moving forward.

  9. Paul Widener says:

    What’s the problem with Taylor Widener? He was lights out in spring training.

    • Brennen Gorman says:

      Lights out in Spring Training, but now has one of the highest ERAs in all of Minor League baseball, he’ll need to string together a few solid outings before returning to the Stash.

  10. Ben Sullivan says:

    Hi Brennen,

    Since your a Tigers fan when do you think it is a good idea to stash Casey Mize. I’m in a keeper league that you can only keep 7 people. Should I drop Forrest Whitley for Mize right now?

    • Brennen Gorman says:

      I do not think Casey Mize is worth a Stash, at least not yet. He’ll be a September call-up at best and I think there will be plenty of other pitchers worth stashing between then and July/August. Might be worth it given your league composition, but hard to say without more. I would drop Whitley for Mize.
