Scouting the Orioles’ Return for Manny Machado

The prospect package acquired from Los Angeles in exchange for Manny Machado is deep on warm bodies who are likely to wear a big-league uniform and produce some kind of value. One or two of those new Orioles has a realistic chance of producing two wins or better annually and making enough noise to drown out the howls of a fanbase that’s losing its most talented player since Cal Ripken.

The collection of talent sent to Baltimore is headlined by 21-year-old Cuban OF Yusniel Diaz and 22-year-old righty Dean Kremer, the latter of whom had recently been promoted to Double-A. Up-and-down utility infielder Breyvic Valera, 21-year-old reliever Zach Pop, and 21-year-old breakout performer INF Rylan Bannon were also acquired in the deal.

Diaz, whom Kiley and I saw this weekend at the Futures Game, is a career .288 hitter who leaves behind a .314/.428/.477 slash line at Double-A Tulsa. Diaz homered twice on Sunday, once to right-center, once to left-center, and had one of the better batting-practice sessions on the World team.

For all that, Diaz hasn’t exhibited much over-the-fence power as a professional, even during his 165-game stay in the Cal League between 2016 and -17. He’s an all-fields line-drive hitter who keeps his hands inside the ball and peppers the right-center-field gap. He’s much more likely to display doubles power in games, which could cap his ceiling a bit, as the offensive bar in left field, where Diaz projects due to speed and arm-strength limitations, is quite high.

There are indications that Diaz might have the means to produce offensively despite a lack of big game power. He has more walks than strikeouts at Double-A this year and could be a premium contact/on-base hitter with gap power. He’s very likely to hit and therefore is very likely to be a big-league contributor, but he looks more like a solid-average regular than a potential star based on how he’s performed thus far. Industry opinion of Diaz’s power remains closer to our preseason assessment (where we put a future 45 on it) and doesn’t correspond with the display on Sunday. If that’s what Diaz is moving forward, our 45+ FV grade is going to be light.

Dean Kremer has pretty narrow range of likely outcomes, ranging from back-end starter to middle reliever. He has a four-pitch mix led by a fastball in the 92-95 range that will touch 97 at times, as well as solid-average overhand curveball. His slider and changeup are both fringey right now, but if Kremer can improve the change and better locate his fasball to his arm side as a way to set it up, then he’ll be fine as a rotation piece. If not, he doesn’t have much recourse against left-handed hitters and would probably be relegated to the bullpen. There’s also a possibility Kremer’s breaking-ball usage and command improve to a point where he can attack lefties without the changeup, the way pitchers like Patrick Corbin, Nick Pivetta, and Robbie Ray. This is a less typical developmental path, but it is becoming more common.

The rest of the players involved in the deal are likely to fill lesser big-league roles. Breyvic Valera was acquired from St. Louis as shortstop depth after the Corey Seager injury in exchange for OF Johan Mieses. He’s a 50 defender at short and can make contact but produces so little power that he’s limited to a bench role. RHP Zach Pop is a low-slot reliever who has a spotty injury history and a violent delivery. Assuming he stays healthy, he’s very likely to be a reliever with a mid-90s fastball and frisbee slider that causes right-handed hitters’ skin to crawl.

The piece in the deal with the largest error bar is 2B/3B Rylan Bannon, who has put up huge offensive numbers at two hitter-friendly locales since he was drafted out of Xavier in the eighth round of last year’s draft. He has some power generated, in part, by a big, exaggerated leg kick and a low hand load that enables him to lift the ball despite a flat-planed swing. He’s vulnerable up in the strike zone and has middling bat control, but as a decent defensive fit at either second or third, there’s a chance he hits for enough power to fit, perhaps part time, at either position. Scouts generally have him written up as a try-hard bench piece, but this is the guy whose stats and scouting report are most incongruous of the players acquired by Baltimore.

As far as Future Values go, Diaz is a 45+ for us right now and was only left off our recent top 131 due to his lack of power output in games, which is a concern for a likely left fielder. He projects as an average regular. Kremer, Pop, and Valera are all 40 FV players, with Kremer having the best chance to outpace that mark if he develops a way to deal with lefties. Pop and Valera are high-probability big leaguers almost certainly ticketed for lesser roles. Bannon is a 35+ FV as a likely org guy with a chance to transform a few niche attributes into something more than that.

I like they got some safe players but isn’t diaz lacking a bit of upside? No real weakness and k-bb rate is a plus but no real plus tool either offensively or defensively.

Sounds like if CF then average regular but at the corner he might be more of a 4th of due to lack of power.

I agree that Diaz is a high floor, low to medium ceiling prospect. His open stance and the bail on his swing leads to a flat bat plane that limits his launch angle and power potential. His exaggerated weight transfer also means that he will struggle any time he’s fooled with off-speed pitches. I really like his eye and bat to ball skills, and it’s intriguing to wonder if he could access more power with some stance adjustments. I think he has enough arm to handle right field, but he certainly would be more exciting if he had the range for center.

I’ll take a guy who can hit first. The orioles won’t have any problems fixing his swing to generate more power. Don’t read this scouting report as the gospel. Fangraphs had Juan Soto listed as a 50FV player as well. Diaz is a 45 FV at his floor, he could certainly be more.

Soto was listed at a 50FV because he wasn’t expected to be close to the majors and had a high volatility score. Nobody ever questioned his ceiling.

https://www.fangraphs.com/blogs/2018-top-100-prospects/ Pretty sure that says MED on volatility. Colin Moran was given a 50 FV as well. I’m not sure his skills are all that different from Diaz.

Seems like prospects with plus hit tools are seeing a jump in power numbers once they reach the MLB. Maybe (most likely not) he could have a Ramiréz or Albies type breakout.

Is it stupid to think that the Orioles, who rely so much on homerun power and play in notoriously batter friendly park, just really imagine opening up his power more? Maybe a 20-25 HR guy?

Maybe this is completely naive, but I’m hoping this trade signals a shift in focus away from the low OBP, long ball hitter.

I would prefer if all baseball went that, so fingers crossed over here.

I was pretty thrilled that 2 of the 3 bats they got back are low strikeout guys.

It sounds like the Dodgers did pretty good and the Orioles just alright, then. I am curious who else they might sell (most of the bullpen, Adam Jones?) and bring in. I am a bit surprised they wouldn’t have taken the Phillie’s offer if Medina was really involved.

I disagree. I think the Orioles did better than what I would have expected. Historically, rental players don’t get the haul that most people expect. To get 5 players that will all likely contribute at the major league level for a half year of a guy they had no chance to resign; that’s a win in my book.

They didn’t. Diaz is the only one of these prospects who is “likely” to contribute at the major league level, but the other four have some chance to do so, especially since the Orioles have more needs than the Dodgers did.

I think all 5 have a decent shot of playing for the Orioles at some point. If any are above replacement level or worth playing on a team that isn’t tanking/rebuilding is the real question, but time will tell, I suppose.

With the caveat that there’s obvious variance in scouting takes, it’s worth noting that Kiley and Eric are a lot lower on Diaz than the industry seems to be. KLaw and BP both have him as a top 50 overall prospect right now. Again, not meant to say one is right and the other is wrong, but it explains why the O’s might prefer this offer to one that included Medina (if there even was such an offer from PHI).

I think you have to say that both teams did well here. Everyone has known since the offseason that the Orioles weren’t going to get a lot for Machado in his walk year. That said, given their shallow farm and a 3+ year rebuild, I think getting one player who has a very high likelihood of being an everyday starter and four others who are varying levels of interesting has to be about a much as you could hope for as a fan. And of course on the Dodgers side you get an amazing player and didn’t have to give up a Gleyber Torres caliber prospect to do it.

I think how you view the Orioles’ return depends on what you think they were offered in the offseason. I think I’d rather have Duplantier than Diaz, but perhaps the O’s saw it differently.

I think that the Dodgers did really well, but the question of whether the Orioles did well is pretty questionable since they could have gotten a lot more for him if they sold him sooner.

Would love to know what was on the table in the offseason and if they ended up taking less by being obtusely stubborn about their chances of contending when it was quite obvious to everyone else that they were DOA this year. I suspect they ended up with less but the fact that Machado rebounded offensively probably mitigated the damage and maybe they ended up with a similar return.

I wondered the same. The idea that they should have dealt him a lot sooner has some real holes. Two offseasons ago, they were coming off the playoffs and reasonably thought they were contenders. At the break last year, Manny was really struggling, with an OBP under .300 and an OPS in the low 700s. This offseason he was coming off a down year and still had only one year left on his deal; it’s still a rental. Plus we know the Dodgers would not have been interested this offseason (Turner and Seager), and I’m not so sure the Brewers or Phillies would have been either. Both teams may have been nervous that they’d make a run this year. So it’s hard to even say what the market looked like.

I actually wonder if the yankees offered more but angelos said no because it is the yankees

Uncle SpikeMember since 2020

Damn! I get that Raylan Bannon wasn’t a highly touted prospect and his numbers are likely inflated due to hitter friendly confines but those numbers are pretty eye popping. Through his first 129 games, he’s at 97 R, 30 HR, 91 RBI, 9 SB. As Eric said, he has the largest error bar of any player in the trade, but someone I would definitely gamble on. He may have the highest upside of any player in the deal.

Could just be a slow developer. Maybe he turns into a solid big leaguer for a few years. I actually like Pop a bit more than they say here, too. He’s really dominated this season – maybe a good closer for a rebuilding team. Which means trade bait again in the future lol

.367/.483/.675 at home
.227/.320/.448 on the road

Huge difference but the power seems real as is the ability to draw some walks and get on base. There’s some definite potential there.

Should add that he’s hit righties and lefties equally well which is a definite plus.

Yeah, all due respect, but slapping a 35 FV on a guy with his numbers (159wRC+)in his first professional season seems borderline stubborn. I get he’s a lotto ticket and unlikely to pan out, but there are some incredibly mediocre players with a 40 on them. A 35 is generally a non-prospect, and that’s a hard case to make for a guy who can defend in the infield and hit for power.

Ya I think a 40 is warranted. I think Kiley put a 40 on him in yesterday’s chat.

He might end up being something, but take those numbers with a grain of salt given that he was a 21 year old in Rookie ball last season and a 22 year old in High-A this season.

I agree on all fronts. I just think “might end up being something” = 40FV. It’s a tiny hill to die on and I won’t, but the grade and the description don’t (plus the numbers, as the article acknowledges) just don’t seem to match.

sadtromboneMember since 2020

I think Eric might be a bit low on Diaz, but overall, even if he’s an FV50 this seems awfully light given that the Orioles were asking for other teams’ top pitching prospect.

I don’t like the return much, but maybe that’s the best they got offered. It’s hard to believe, though.

Just goes to show that the rental market is really not what it used to be.
