Yusniel continues his slide in the prospect pecking order on the Orioles. Not good for Yusniel but good for the O's.

He's No. 6 in Baseball America's rankings that came out today.


  1. BA Grade: 55. Risk: Very High
    Tool Grades: Hit: 55. Power: 50. Run: 50. Fielding: 50. Arm: 60.

    Track Record: Signed out of Cuba by the Dodgers for $15.5 million after the 2015 season, Diaz has spent three seasons in the U.S. trying to translate his considerable tools into consistent production. After being acquired in the Manny Machado trade in July 2018, Diaz impressed in his first big league camp with the Orioles, but a hamstring injury early and a quadriceps injury late limited him to 76 games in a stop-and-start year at Double-A Bowie.

    Scouting Report: Diaz has been trying to find a swing path that best utilizes his plus bat speed since turning pro. He’s found success closing his stance and standing closer to home plate to cover more of the plate, but he’s still prone to selling out for pull power. He produces with runners in scoring position and will take a walk. Overall he projects an above-average hitter with 20-home run power. Diaz is capable of filling in at center field but is best in right field, where his average speed and plus arm profile. His in-game habits and overall instincts are inconsistent, but his pregame work draws praise from coaches.

    The Future: Diaz has the tools to be an above-average everyday player, but hasn’t consistently shown the production for it. He’ll start 2020 at Triple-A Norfolk and will be in position to make his big league debut.

Baseball America came out with its Mid-Season prospects top 30s for every team.  They didn't match my Orioles rankings exactly, but they did have Diaz, Mountcastle, and Hays slide.  

The new list is much better than it was before this season.

1. Rutschman

2. DL Hall

3. Grayson Rodriguez

4. Yusniel Diaz

5. Mountcastle

6. Hays

7. Gunnar Henderson (2nd round pick)

8. Hunter Harvey - obviously the depth isn't there when the oft injured Harvey still resides in the top 10.

9. Dean Kremer - I like this guy, as I've said before

10. Michael Baumann

It will be interesting to see the other movers before next season's pre-season list, because the Orioles signed around 30 international free agents.  Six of their 30 have no BA scouting report.  Imagine going from one of the bottom 5 minor league systems a year ago to one of the top half this year.  It's a long way to go to reach the level of the tampa-bay-rays.

After some injuries in the first half, Diaz is finally hitting for the AA Baysox.  255/336/485 with 9 HR and 12 doubles, 3 triples.  

Austin Hays is back at AAA Norfolk too after a few weeks on the shelf.  he too has 9 HR and 12 doubles, but worse stats across the board: 234/283/467.  

Ryan Mountcastle has moved to 1B and his power seems to be to the point that he can hold down the position.  As a 22 year old at AAA, he's hitting 300/322/499 with 16 HR and 18 doubles, walks be damned.

DL Hall came in as the Orioles top pitching prospect and he's doing okay.  His walks are a little out of control. High-A 3.57 ERA with 87 Ks and 44 Walks in 58 IP.  

But, they've all been jumped.  Not only is Adley Rutschman #1 on the Orioles' list, but their 1st round pick from last year has jumped too.  At age 19, Grayson Rodriguez is carving up low-A with a 2.15 ERA, 87 Ks and 22 Walks in 67 IP, after throwing a 1.40 ERA in limited action in Rookie Ball last year.  DJ Stewart is hitting 303/410/576 at Norfolk.  He's had a couple tastes of coffee (I wouldn't call them cups yet).  He looks like a legit DH candidate.  Second round pick Gunnar Henderson probably is ahead of the guys from the top of the list this spring too.

Rebuilding takes a while.  The guys in the high minors aren't the future of the Orioles.  They are the next couple of years.

Hit his 6th HR in AA.  Still only 241/318/445 in 137 AB.

After coming off the DL he's finally hitting in AA.  Maybe I'll take a ride out to Bowie to see him in person.

Yusniel Diaz, RF, Orioles. It's going to be a rough year in Baltimore, but it will be a little easier if some of the Baltimore's young prospects step up. Diaz has impressed so far. He went 2-for-3 yesterday and is hitting .471 (8-for-17) so far.

Copying from Eugene's post in the archive -- BA's assessment.

The Future: In terms of ceiling and present pedigree, Diaz is a
peerless talent among position players in the Orioles’ system. He’s the
closest thing to an everyday impact player that the farm system boasts,
and even if he doesn’t show his entire range of skills immediately upon
his arrival to the majors—which could be as soon as early 2019—Diaz is
the type of player who will contribute enough to stick and grow into an
above-average everyday player. He may push for a roster spot out of
spring training, but with several other young outfielders on the roster
already, Diaz may have to wait his turn at Triple-A Norfolk.

So, a bright light for sure on the Orioles. Measured against all the other prospects in baseball?

Where Diaz ranks on the top 100 lists

Baseball America: No. 37

Baseball Prospectus: No. 44

Baseball HQ: 54

Rotowire: No. 33

No one puts him among the elite. Everyone thinks he's going to be a solid player. His ETA is 2019.

If even one of these minor league gurus ranked him in the top 25, I'd make him an R1 in the software. But no one does and I'm making him an R2.

Doesn't mean he'll be available in the second round; he won't be (if he starts the year in the minors). Just means he's unlikely to be an impact player. Not this year.

Now, if he has a nice spring training but starts the year in the minors anyway, to delay the clock, I can always change him to an R1 in the final update.

Another factor: if the elite prospects, like Vlad Jr. and Eloy, actually start the year in the majors, I'll want to bump Diaz to an R1.

It's all relative, no? If the R1s are bought in the auction, the best R2s in the reserve draft get promoted to R1.
