    TD Top Prospects: #7 Adalberto Mejia


    John  Bonnes

    Cloudy bad seasons are supposed to provide some trade deadline silver linings. Left-handed starting pitching prospect Adalberto Mejia is the shiniest bauble the Twins acquired at last year’s deadline, but that’s about the only time you’ll see the adjective shiny in a sentence about Mejia. His strength is that he’s very likely to contribute to a MLB organization, rather than dazzle with enticing upside.

    The Twins acquired Mejia last year when they traded Eduardo Nunez to the San Francisco Giants. Mejia signed with the Giants in 2011 out of the Dominican Republic, was in Low-A ball by 2012 and has basically climbed a level per year. The exception was a repeat of AA in 2015, which was likely the result of a 50-game suspension for using a banned stimulant.

    He’s had decent overall success – his career ERA in the minors is 3.70 – and was well-regarded but the southpaw with the low to mid 90s fastball never posted eye-popping numbers. That changed a bit last year for the 23-year-old as his strikeout rate in AAA climbed to more than one per inning and his walk rate plummeted to 1.9 BB/9. The prevailing theory was that the hefty Mejia’s improvement was at least partly due to losing some weight and gaining some conditioning in 2016.

    What’s To Like

    He checks a lot of boxes. He’s left-handed. He’s had success and been fairly durable. He’s just 23 years old. Last year he had an awfully good strikeout and walk rate despite moving up to AAA. He has a decent fastball and a slider that he can use effectively versus left-handers (who had just a .548 OPS against him last year) and a changeup for right-handers (.694 OPS against). Finally, he’s very close to major-league ready right now, if he’s not already there.

    What’s Left To Work On

    What you see is what you get. There isn’t a lot of upside here; Mejia's fastball isn’t likely to get any faster and the other pitches, while good, aren’t great. There will always be concerns about his conditioning. His walk rate and strikeout rate in AA in 2014 and 2015 were both pretty pedestrian, so it's essential he carry 2016 forward. His stuff suggests he’s unlikely to make an immediate positive impact in the majors; there are probably going to be some additional growing pains.

    What’s Next

    Mejia has an outside chance to break camp with the Twins, but he’s arguably eighth in the pecking order for the rotation’s five spots. Instead, it is far more likely that he’ll return to Rochester as a starting pitcher and compete for a chance to fill in a rotation spot when it becomes available. I’ll be surprised if Twins fans don’t see him at some point this year.

    There really is no hurry here. Mejia is just 23 years old and he has two option years left. Development is still the priority for Mejia, unless the Twins end up with a far more competitive team than we expect.

    Long-term, his upside is that of a durable and effective mid-rotation left-handed starting pitcher, which would have enormous value for the Twins. At the very least, a career as an effective left-handed reliever appears within reach, especially if he can pump up that fastball a bit in shorter stints.

    For some reason left handers seem to be able to pull this off. David Wells, CC Sabatthia, Carlos Silva, Eddie Guardado.

     

    Also, for some reason velocity tends to play up for lefties.

    I didn't realize Carlos Silva was amphibious...I mean ambidextrous... I mean left handed.
    I like Jay and Gonsalves better, but what I really don't like is the logjam in MLB that needs to be cleared.  Jay, Gonsalves, Berrios, May, Mejia would be a nice rotation to see at the end of the year.  It's time to quit investing in old and average (or worse) and start getting these young arms ready to compete.  In addition, teach Duffey a third pitch, like coaches are supposed to do.  I want coaches to do their job and get us set up for a good number of years to be competitive.  The bats are lining up, lets get the arms ready too and if we suffer some this year at least we have the potential for next year and beyond.  What is Vogelson, Santana, Santiago going to do for us in 2018 and beyond?

     

    I like your post. And I agree with it for the most part, but also have to disagree a bit. I agree there is a bit of a logjam for the rotation. Not including fringe guys like Vogelsong or a sudden, unexpected promotion of a minor leaguer, a healthy Hughes, (at some point), Santana, Gibson, Santiago, Haley, May, Duffey and Berrios give 8 legitimate SP options. So you are correct there is a bit of a logjam, and I'm actually glad we didn't invest in any additional FA options. But we are uncertain on Hughes, for now. Berrios is still very young and has options if it's decided to go another right to begin the season, and a couple of these guys could also see themselves in the pen.

     

    Which brings up the second point. I absolutely agree that an end of the season rotation of Jay, Berrios, May, Gonsalves and Mejia would be excellent and exciting. And I see a lot of possibilities of both Santana and Santiago being moved at some point to contending teams needing additional pitching help. It would make sense not only to clear dollars and maybe get a decent prospect or two, but to make room for at least one prospect, and create a better roster opening in 2018 for a prospect, major trade acquisition or FA signing.

     

    But the counterpoint would be:

     

    1] Hughes is untraceable at this point. We're he to come back to form..at some point at least...he could be more valuable to keep.

     

    2] Almost ditto for Gibson, though less of a post-injury concern. But again, healthy, back to his 2015 form, perhaps even better, while trade able, he could also be more valuable to keep. Especially considering its a little hard to simply graduate multiple pitching prospects, with any success, all at once.

     

    3] While Jay offers a TON of potential...and I simply don't understand those that are down on him so soon...he has only a single full milb season under his belt. He is still developing a feel for being a starter and building up endurance. I think he's a full season away, at least, and I'm OK with that.

     

    I expect, and hope, that by the end of the season, we are looking at a rotation of Hughes, Gibson, May, Berrios and Mejia with an appearance for Gonsalves. Now ask me how excited I am with those 6 in the fold for 2018, with more on the way, and the possibility of a major trade or FA signing?

    That bugged me too until I learned that it was confirmed that Mejia reached his innings limit.

    He could have been called up earlier, he was already on the 40-man roster. Milone, Dean, and Albers all started MLB games for us in August while Mejia was relegated to starting in AAA.

     

    I did a little research:

    Mejia was a great get for Nunez, in my opinion... he just looks a little Mjaresque to me... not that I'm one to speak... 

     

     

    Baseball America had him as the No. 5 prospect in the Giants system at midseason last year. I don't think you should be disappointed by this.

     

    I get that people want the huge prospect upside, but as lefty with good control and the ability to miss some bats, Mejia is a very safe bet to contribute positively in some form. And based on reports I've heard about his improving slider, I think his ceiling is a tad higher than John suggests. But (as you can see from Seth's breakdown of individual rankings above) I'm higher on this one than most.

     

     

    I don't know.  We've seen a lot of "#4 starters" come through Minnesota lately who offered little or no trade value.  Milone is a good example, a guy with team control and relatively low salary.  Useful at times, contributing league-average performances at the back of a rotation, but never had much value in trade.  Some veteran arms that might fit that performance profile too: Nolasco (see what he was traded for in 2013), Pelfrey, Santiago, etc.

     

    Obviously if Mejia does well, he'll be useful and he'll have some value.  But I'd stop well short of projecting it as "enormous" or "considerable" right now.

     

    I think the difference is that Mejia is 23 (and will be this entire year) and cost controlled for years to come (including multiple years at the rookie minimum) while guys like Milone, Nolasco, Pelfrey and Santiago were more expensive with less room to develop (and perhaps closer to #5 than #4). There's a big difference between a guy you can slot in at the back of the rotation and don't have to pay for several years and a guy earning $14 million a year (or a guy with a $5-$10 million arbitration award coming).

     

    Enormous may be too much but considerable seems fair. We're all so starved for top-of-the-rotation pitching that we're not appreciating the value of a solid, cost-controlled back of the rotation arm.

     

    Dear All,

     

    Take heart. At one point in time, these were our top prospects:

    and now we see why it is we've been so bad of late.

     

    I don't know.  We've seen a lot of "#4 starters" come through Minnesota lately who offered little or no trade value.  Milone is a good example, a guy with team control and relatively low salary.  Useful at times, contributing league-average performances at the back of a rotation, but never had much value in trade.  Some veteran arms that might fit that performance profile too: Nolasco (see what he was traded for in 2013), Pelfrey, Santiago, etc.

     

    Obviously if Mejia does well, he'll be useful and he'll have some value.  But I'd stop well short of projecting it as "enormous" or "considerable" right now.

     

    There's different kinds of 4th starters. Milone has a lot more risk given his complete inability to miss bats.  Mejia has at least shown the ability to do so (so far).  Even if the end game is a 4th starter, there's a lot less risk to a guy like Mejia if he's getting 7k/9 with a decent BB rate. That type  of pitcher can be flipped for something decent at the deadline.
