Wilman Diaz – Back To Prospect?

With catcher Diego Cartaya in 2018 and outfielder Luis Rodriguez in 2019, the Dodgers signed the top ranked Venezuelan prospect two years in a row. In their 2020 class, they signed another top Venezuelan prospect, SS Wilman Diaz, Maracay, Venezuela.  He was the overall #3 International Free Agent in the 2020 class.

According to industry sources, Wilman signed for $2,697,500.  The Dodgers also signed another Venezuelan catcher in the same draft group.  The #8 prospect, Jesus Galiz, signed for $812,500.

Wilman is from the same program that touted catching prospects Diego Cartaya and Yeiner Fernandez played at prior to signing with the Dodgers.

Diaz not only was MLB Pipeline’s third-ranked prospect, but additionally the highest-ranked teenager of his class. The 17-year-old’s best tool as hitting, having received a 60 on the 20-80 grading scale.

Diaz also is a capable defender at shortstop and has gotten rave reviews about his arm strength. Although he now seems to be working more around the infield.

Here is his pre-draft scouting video:


Wilman broke into the LAD Top 30 prospects at #9 in 2021.  His scouting grades were:

  • 55 hit, 50 power, 60 run, 55 arm, 55 field, 50 overall

After his first year at DSL, Wilman dropped to #25 in 2022.  His offensive scouting grades dropped while his defensive grades improved.

  • 45 hit, 45 power, 60 run, 60 arm, 60 field, 45 overall

After his 2022 season at Rookie League in the Arizona Complex League, Diaz dropped out of the Top 30 prospects.  That was reflected in the FanGraphs Scouting Report in 2023.

Scouting Reports history:

December 2020

  • Diaz has a good balance of tools, skills, athleticism and physical upside. He’s 6-foot-2, 165 pounds with a loose, low-effort swing, good bat speed and plate discipline with good performance in games. He hits for power in games too, showing the ability to backspin balls to the pull side and drive the ball with impact to the opposite field as well. He still has a lean, athletic frame with a lot of space to fill out, so his power should climb once he gets stronger. Diaz also has the athleticism and actions to give him a good chance to stay at shortstop. He takes pride in his speed, which has improved to a plus tool, and he plays under control in the field with good hands, footwork and an above-average arm.

December 2021

  • Diaz has all the ingredients to hit with advanced plate discipline, short actions and a loose, easy swing. He does a good job staying behind the ball and has plenty of room to add strength. Diaz projects to be an above-average hitter with at least average power, but he still has some swing work ahead. The Dodgers plan to work with him on staying in his legs more and keeping his hands closer to his body to create a more linear bat path. Diaz is more polished on defense. He’s a borderline plus runner with plenty of range, sure hands and plus arm strength from shortstop. He’s a good athlete who projects to stay at the position even as he adds weight and strength.

FanGraphs 2021 – Scouting Report

  • Diaz has filled out a bit in the middle and does not have the same level of rotational explosiveness he did as an amateur, when he had some of the most exciting rotational athleticism some scouts had ever seen. This may be because the Dodgers have altered his swing, especially the way Diaz uses his lower half, as a way of helping him remedy plate coverage issues they thought would come with his old swing. During 2021 instructs and ’22 spring training and extended, his feel to hit has been middling. He’s not squaring pitches up with any authority and has tended to hit a lot of low liners and grounders. His defense at shortstop has been as advertised, though, and he finds lots of creative ways to turn the baseball around to first base. The context surrounding Diaz’s current look — namely that he had a huge amateur profile (he was one of the more exciting, tooled-up players in his signing class) and is currently going through some mechanical changes — are important to consider here, but if you walked into Dodgers camp without knowing any of that, you’d think he was a glove-oriented utility prospect, similar to Jacob Amaya except several levels behind him.

FanGraphs 2022 – Scouting Report

  • An extremely high-profile amateur prospect, Diaz plays a very good shortstop, but he’s struggling to cover enough of the plate to be viewed as a potential impact player even after changes to his swing. The wowing rotational explosiveness he showed as an amateur quickly dissipated in pro ball, though some of this may have been due to the swing alteration. At this point, we’re talking about a 30-grade hitter with a 30-grade approach, someone who might be a glove-first bench option down the road barring a surprising resurgence.


His 2023 start at ACL was so much better than his 2022 season that he was moved up to full season A League at Rancho Cucamonga.  Something has clicked for Wilman, as he is hitting much better at RC.  He still has a little too much swing and miss, but maybe that will come as he gets more comfortable with his new swing.

Wilman was just named California League Player of the Week.  Diaz had a great week for the Quakes, going 12-for-21 with a triple and four home runs. Diaz was assigned to Rancho Cucamonga from the Arizona Complex League Dodgers on July 18 and has not looked back.

Maybe, just maybe, Wilman can find himself back in the LAD Top 30 prospects.

Safe travels. Really enjoyed the read on Diaz. Would like to keep him at SS as long as possible. I wonder how his skill set compares to Doncon’s . . .


Scouting grades: Hit: 45 | Power: 55 | Run: 45 | Arm: 55 | Field: 50 | Overall: 45 

“Signed for $497,500 out of the Dominican Republic, Doncon has been the top performer from the Dodgers’ 2020-21 international class. He made an easy transition to pro ball in the Rookie-level Dominican Summer League in 2021, then came to the United States last year and showed increased strength and power. He finished last summer by homering three times in 11 Single-A games as an 18-year-old. 

Doncon’s combination of hitting ability, bat speed and projectable strength give him at least plus raw power that plays to all fields. He has an aggressive, pull-happy approach but also a knack for putting the barrel on the ball with a right-handed swing that he repeats with ease. While he may have to make adjustments against more advanced pitchers, he has at least 25-homer potential.

Doncon presently shows average speed and can steal an occasional base, but he projects as no more than a fringy runner once he’s physically mature. The Dodgers like his actions at shortstop, where he was more consistent in 2022 following an erratic debut, and he has the solid arm strength for the position. If he loses some quickness, second base may be his long-term home.”

He was rated considerably higher than Diaz at the beginning of the year.

Who are considered the long term jewels of the organization? I wouldn’t know, but the rankings outside the Top 10 change within the year. The best might be blocked, in which case they can be used to bring in whatever is needed. Unless of course, that piece that was deemed necessary backs away from playing with this organization.

9-10 hours!

for a soccer tournament?


A stat for Badger:

Dodgers are tied for 2nd in MLB for most shutouts pitched.


Well that no doubt helps them from dropping any further than 19th, where they are now.


Miller + bullpen were great last night.

Urias now with 14 consecutive innings without giving up a run. Apparently Urias has had a split nail on his throwing hand that has affected his pitches and has been slow to adjust to the pitch clock.

Kershaw about to return. Buehler might be ready to make a difference in the playoffs. May now with even longer bigger hair.

I’m hoping for greatness coming to 3rd base next year. Michael Busch is now hitting – .326/.433/.621/1.054. Will it be Busch or will Busch be used to get that guy?

AZ announcers said their team while winning early in the season were eager to get to the ballpark and were having fun but not so anymore. People are entertained when watching someone having fun. That kind of comment while accurate could be rightly criticized by management. I mention that in context with the Baltimore announcer that has disappeared for merely verbalizing what was on a chart prepared by statheads about the Orioles having a history of difficulty playing at Tropicana Field.

ACJeff has written about using a piggyback pitching for the Playoffs. I have suggested using it during the regular season. I like it.


Arizona has lost 8 in a row and are now a -21 RDIFF. Colorado is just a bad MLB team. We should get healthy against teams like these.

I think it’s possible, even likely this staff will pitch better the rest of the way.


The part of me that is resistent to acknowledge the Padres’ slo-mo collapse is the list of teams above them vying for WC3.

I just don’t believe in any of those teams. I guess baseball is now the NBA, with bad teams making the playoffs.

Re: Wilman Diaz
How do you have a slash line of .373/.403/.716/1.119, yet strike out almost 40% of your plate appearances and walk less than 6%.
Seems like his stats are pulling in two completely opposite directions.

I can see what the appeal was when they scouted him, both offensively and defensively. Now, we just need to cut down on those k’s.


Answering that question correctly is sort of hit and miss.

Singing the Blue

Well done, Maestro Fred.


Babip god?

Singing the Blue

Just checked his BABIP at Rancho, Big D.
You hit the nail on the head.
It’s .538 (FIVE THREE EIGHT). I don’t think I’ve ever seen a number that high for that category.
