Scouting Rusney Castillo, From Video
Rusney Castillo is set to make his Major League debut in mere days after signing a record contract for a Cuban defector. Cuban players are the most interesting to project, since the public tends to have about as much information as teams do to process and make a decision on their futures. I started writing this article before Rusney Castillo signed with the Red Sox, with the goal of figuring out how his bat will play in the big leagues. Going forward I will also be contributing in a modest fashion to the robust scouting team that Kiley McDaniel has assembled, with my motivation and experience still focusing on hitters.
As such, this article is a bit of a hybrid between a concise scouting report and my usual shenanigans breaking down available videos. I promise to both you the readers and Kiley I will follow protocol more consistent with the rest of the team in the future. Check out his report on Castillo as well as Dave Cameron’s article for their more distinguished viewpoints. Kiley has a lot more contacts than I do in the scouting world, so treat this as only my take rather than a more informed opinion. Without further ado, let’s look at his tools before getting into the nitty gritty of his swing.
SPEED
Home to First: 4.12 seconds
Home to First on Bunt: 3.67
60-Yard Dash: 6.39 listed (6.55 by my count via video)
The running game is Castillo’s most readily apparent weapon, and it plays on both defense and offense in a plus-plus fashion. On the 60-yard dash from his showcase, he makes a false step before going forward, leaving his exact time up for debate. Regardless, either time makes his speed a high quality tool. If beating out ground balls for hits is what you’re hoping for, he may leave you disappointed. His swing takes him toward the left side of the diamond most of the time, making him a bit slower out of the box due to having to change direction. When he bunts, there’s no doubt he’s a menace, and with good placement it’s a guaranteed hit at that speed.
There are a number of clips of his baserunning but not many of him stealing off the pitcher. His speed plays just like it should taking extra bases on hits, and the rest of his value there will depend on his ability to get good jumps on Major League pitchers. For what it’s worth, over his last 1097 plate appearances in Cuba (2011-2013), he stole 66 bases while getting caught 22 times, good for a 75% success rate and a steal once every 5.4 times on base (counting singles, doubles, walks and hit-by-pitches; 4.6 if you take out doubles).
His aggressiveness and speed lead me to believe he will steal 25-30 bases over a full season, with more of his value coming from taking extra bases and supplementing his defensive play. Though he is not young, he is not old enough yet where we should be worried about a swift drop-off in his value here. I give him a slight discount on his present grade while he figures out how to traverse MLB pitchers and catchers on the bases.
Grade (Present/Future): 65/70
2015 Value: ~0.5 WAR
ARM
Castillo carries a strong arm into the field, fueling hopes he could play a solid right field even if his legs started to fail. His upper body strength is an asset and a liability here, as his arm action can get a bit stiff with his shoulder muscles tending to really heave his arm through. This is the reason for me why he profiles solely as an outfielder.
In the half dozen or so game clips I saw of his throws, he seems to need a few extra pre-throw steps to be consistently accurate. From a standstill he does not incorporate the rest of his body much, relying on his shoulder strength to get the ball going. We won’t see any Yasiel Puig-like throws from the wall with Castillo.
I don’t have any gun readings, but even if he does have 60-grade arm strength, I think it may only play as a below to fringe average tool when truly tested. If he were a pitcher I would be worried about shoulder injuries in the future. For this reason I think he may lose a tick over the next few years in this department.
Grade: 45/40
DEFENSE
Here, Castillo has a strong reputation as a plus defensive outfielder with the range for center field, and there is nothing in his highlights that suggest otherwise. He makes long running plays look easy, not wasting any time to get to the ball’s landing spot. He has a very soft glove even on plays where he has to jump or extend for the catch. In his showcase work he receives the ball well on double play feeds and batted balls alike, and strictly with his hands he would not be a train wreck at second base in a pinch. He looks comfortable ranging to his left and right and seems to have solid field awareness, allowing him to use the far reaches of his speed to haul balls in. I still don’t feel comfortable projecting any relatively unknown player as one of the best defensive outfielders in the game, but his playable range alone gives him a chance to be that guy.
Grade: 60/65
2015 Value (Total Defense): ~0.7 WAR
HIT/POWER
*Just my personal preference, but I don’t like to talk about these as separate tools. They are too interdependent when trying to determine the value of a player’s bat in my opinion. There are a few exceptions, but in general I believe you can’t hit for power if you can’t square up Major League pitches, while defenses won’t respect a hitter’s ability if he has no pop behind it. I will still list the grades separately, but the discussion for each has a lot of overlap.
Castillo’s reputation for playing with high energy is obvious in even a cursory look, and in the batter’s box is no exception. His aggressiveness may hint at a high chase rate on pitches out of the zone, but he shows a pretty solid knack for getting the bat to the ball in all areas around the plate. Castillo’s strikeout rate over 2011-2013 compares favorably to the three years Jose Abreu and Yoenis Cespedes had before they each defected, though his walk rate was well below both. For a less recent comp, back in 2005-2007 Alexei Ramirez walked about 50% more often in the Cuban National Series than Castillo.
So in Castillo we are likely looking at a low walk rate, low to medium strikeout rate type hitter from a discipline perspective. Getting on base at a decent clip will require his BABIP to stay at a high level, which bodes fairly well considering his bat speed and general athleticism. However, if you have gotten anything out of my previous work, I hope it’s an acceptance that bat speed is only a (sometimes useless) part of the equation. Let’s take a look at his swings to get a better idea on his projections. Here are two swings off the same pitcher, the first a fastball away that Castillo drives for a double, and the second a middle-in breaking ball he grounds through the left side of the infield:
A few things jump out right away. Castillo’s shoulders stay very level leading up to the ball and again right after contact, leaving his bat flat as it comes into the zone (i.e. parallel to the ground). This movement provides him with little natural lift in his swing. The shoulders look rather rigid, and the back shoulder in particular looks like it has to push the hands through the zone. His hands look as though they don’t get on plane with the pitch until right at contact, and as a result his barrel spends very little time in line with the flight of the ball. At or just before contact his hands are already moving back across his body toward his open shoulder, making his window for squaring the ball up very small.
On the positive side, despite the side-to-side movement of his hands, his legs stay right underneath his body the whole swing. The core of his body drives efficiently into the ball, and there is good turn of his hips while keeping his front foot down flush with the ground. If the hips were less efficient, we might see the plane of his belt change as one of his hips collapsed or had to work harder than the other, or see him fly open with his knee and/or foot as he follows through.
A level swing like his can be more susceptible to pitches lower in the zone, so let’s see a ball down that he gets up in the air:
His back shoulder again pushes the hands, which look like they are still going down when he makes contact before coming across his body level to the ground. His shoulders tilt a bit more, but not in a way that allows him to lift the ball with his swing path. Instead, he hits it up because his bat contacts the bottom half of the ball, resulting in a less efficient transfer of force and a small margin of error if he wants to consistently drive this pitch. Even on a difficult pitch here, his lower half stays supportive under his swing, so at least his hands and head are working from the same position despite the change in height of the pitch.
Next we get a look at his swing from the side view, this one on another low pitch.
Starting with the lower half, Castillo gets to a strong position with both heels on the ground. As his front heel gets down, the hips really lead the turn of his core, with his knee staying over the back foot until the hips start. His front side accepts the force of his stride and rotation without leaking forward or open to the third base dugout, and he drives his front heel into the ground as he makes contact. There is a lot to like in this part of his swing.
In the upper body, we get a better look at his hand path than we do from the pitcher’s view. The first move of his swing comes from the back elbow starting to drop under his shoulders, though it does not happen independently. The barrel of the bat starts to get away from Castillo here, adding some unwanted length very early in his bat path. As a result of this “laying off” of the bat, his hands don’t follow the elbow down behind the body, but instead start to push forward and down at the same time. Because of this move, his hands don’t get on plane until all the way at contact, descending all the way through the swing. This chop-down swing, while desirable in some eyes, is what makes his head continue forward through the swing, rather than staying on his legs and allowing the swing to work under his head. Then the follow through comes across the body and out of the line of the pitch immediately after contact.
His swing path is going to be the limiting factor in Castillo’s ultimate ceiling. Even if we believed he had the raw power and contact ability to be a .300/30 homer type of hitter, his swing does not allow him to adjust to slight timing changes and still put the ball in the air, like that type of hitter has to be able to do. He is still going to hit balls extremely hard for line drives:
But his swing path and resultant propensity for pushing the barrel out and across the ball will result in a lot of balls hit with topspin rather than hit flush or with backspin.
That is not to say Castillo will not hit for power at all. I would never want to miss up in the zone to him.
He’s going to demolish mistake pitches, and Fenway Park will be the friendliest place of all for his type of power.
Even though his hands want to chop on pitches lower in the zone, they can come through more level or on an incline when the ball is up with the same approach. In the side shot you can see how much longer the barrel is in the way of the ball, and his wrist roll doesn’t have to happen as early because of the pitch location. This is where he is going to make pitchers pay, so it’s really a question of how often he gets balls up in the zone, a la vintage 2011 Dustin Pedroia.
Castillo seems to have the strength to be able to muscle balls out lower in the zone, but his timing and hand-eye coordination will both have to be in the elite upper echelon to do it with any kind of consistency. Swinging down on a ball that is falling down and hitting it in the air is tough to do. His swing plane is still clearly of the low line drive type, though the speeds off the bat should be pretty impressive, likely leading to a high BABIP.
For some swing analogs, a few hitters came to mind that utilize similar bat paths in Major League Baseball, often swinging down and other times being more level, almost always swinging across the shoulders:
Shane Victorino’s name has come up in other analyses of a possible model for Castillo’s abilities, including Dave’s work from a few weeks ago. He’s a bit less shoulder heavy, though he has a very similar bat path from the right side. I like him the most of the three as a (rather loose) approximation of Castillo’s potential as a guy who may be a good to great outfielder some years and a 5-win monster year if everything clicks in the same time period.
Melky Cabrera has better hands than Castillo, giving him the leg up in the AVG department, but Castillo’s raw power gives him similar upside. Brian Dozier would be the best-case scenario given the skill set. Both of these hitters use the lower half well to drive the ball like Castillo. Both are also more relaxed with their shoulders as they swing, giving them an advantage in hand path, which for me is easier to bet on from consistency and ceiling outlooks. These two are likely better models for only Castillo’s best offensive year(s), since a more relaxed approach would be almost contradictory to his established performance baseline.
Castillo did put on quite a power display in his showcase swings last month, elevating balls with more ease than in his game footage.
I am a believer in his strength to hit balls out of the park at a plus level…during batting practice. For his part, Castillo does not hint at a conscious change in hitting approach in interviews, saying “My No. 1 objective would be to be the same player I’ve always been, to play my game and not try to do too much or try to become someone else.” Count me among those who think he is not going to be developing a power-centric game in the next few years, though I wish he would. I see many doubles in his future coming more from his speed than his thump.
Hit: 50/55; with high variance owing to BABIP reliance
Power: 40/45
Raw Power: 60
2015 Value: ~0.8 WAR
2015 Batting Line(!): .268/.308/.430
! = For the inevitable fantasy questions
SUMMARY
Adding up my extremely accurate value projections, we get about a 2 WAR player with the potential for another win or two coming from his bat in a good year. To bet on the over offensively is to believe he is athletic enough to make hard contact at a near elite rate despite some swing deficiencies, which I cannot refute as a possibility. I would also not be surprised if there was another half win on the defensive side. Considering his contract calls for him to be paid market-price for this value, and there are some encouraging reasons to believe it is a modest estimate, the Sox appear to have done well making a solid upside play with a high floor.

good analysis and pretty much in line with my expectations.
Thanks Dan. You mention that his K rate compares well to Abreu and Cespedes. Would you expect his contact rate and swinging strike rate to also be similar (~75% Contact/~10-15% sw strike range)? I like the comps you give for swings, but the success of those players come with a higher contact rate and lower swinging strike rate than Rusney’s fellow Cubans. Roughly their contact/sw str are: Victorino 85/6, Melky 88/5.5, Dozier 85/6. Is there room for Rusney to become more of a contact hitter or will what you said about his bat, “spending little time in line with the flight of the ball,” prevent him from being a high contact guy? Thanks for the in-depth look, looking forward to seeing Rusney in the majors.
PS- why are his minors numbers not available on this site?
Great comment. I definitely believe in Castillo as an athlete, in that he will fare better than his swing may suggest. But I don’t think he will be quite at the same level of those three in the contact department. I do think he will make up for it with a higher BABIP because of the bat speed. It’s tough to know exactly how his contact/swinging strike percentages will play out.
It’s funny; I’ve been having a lot of conversations about this with other coaches. Contact hitters tend to be steeper to the ball than power hitters, but it’s a question of which comes first. Can high contact guys get away with being steeper and shorter on the pitch plane because of superior hand-eye coordination? Or is there something inherently better for contact about swinging down that I don’t understand yet? Of course, the best hitters in the game combine both, on plane longer and great bat-to-ball skills.
Excellent analysis.
Sounds like if he got more lift in his swing, he’d be sort of like Carlos Gomez. Do you think he has it in him to make that change, or are his hitting mechanics pretty much what they’re going to be?
(If I recall correctly, Gomez was told to try to keep the ball on the ground early in his career, but once he abandoned that approach his natural swing plane led to his current power.)
You’re right about Gomez. I don’t think it’s outlandish to think he could do that, but I also don’t think anybody in Boston would have the cojones to rework his swing after giving him $70 million. However, based on some of his showcase swings it might just be a change in approach. Stay taller and let the hands work under the shoulders more to lift the ball. Still tough to give him more than an off-chance of making that adjustment though. He’s not old, but you don’t see big transformations like that without facing some adversity first.
Over the past 3 years, Gomez has hit .278/.335/.486 with the 3rd most valuable outfield defense and the 10th best base running.
Even if he does add loft to his swing, it sounds like he isn’t quite as good of a hitter, has less raw power, has less arm strength, has less speed, and has slightly lesser defense. Expecting him to be even close to the 8th most valuable position player with a mechanical change sounds exceptionally optimistic.
You’re right. Nobody’s expecting that. Mechanical changes can have drastic effects on production, though. Ask Gomez.
Being susceptible to lower pitches might be a red flag in today’s game as the strike zone has lowered contributing to the drop in offense. His overall skills, though, could help to compensate. Nice analysis.
No doubt. From highlights I’ve seen of different Cuban players, slow, hanging curveballs seem to be a lot more prevalent in their game than what we see in the big leagues. Pitchers are still going to miss in his wheelhouse though.
So you are projecting plus speed and plus defense and a .738 OPS, but just 2 WAR a year? This doesn’t make sense. Over the last 3 seasons, Span, Jennings, Bourne, Cain and Gentry all have this basic profile and all have an OPS over that time under .738. They combined to accumulate 44.6 WAR over 1802 games for a 150 game per season WAR of over 3.7 WAR. Which is not that close to a 2 WAR projection. Looks more like a 3.5 WAR player at least.
Your point is well-taken, and your comment could be latched right onto the end of report summary since we’re basically saying the same thing. The difference in numbers comes from the fact that I made my WAR estimates comparing Castillo’s tools to similar players, and understood these run values as compared to replacement level, when in fact replacement runs are added after the individual run values are calculated. There are reasons to believe each of these players are superior to Castillo though:
– Span gets on base better than I’m projecting Castillo to, and his defense probably represent Castillo’s best-case comparison.
– Jennings has a bit more pop and walks more than Castillo likely will.
– Bourn’s OBP, baserunning and defense are all better than I expect from Castillo.
– Cain’s numbers from 2012 and 2013 are pretty close to what I expect from Castillo, so nitpicking the WAR estimates, maybe I would lower Castillo’s offense number a few runs to make up for the confusion of replacement runs. This year Cain is hitting for the highest single season average I would ever expect from Castillo, so not a bad example.
– Gentry’s years over that 2-WAR mark have come as the result of superb defense and very good OBP. I can’t project Castillo’s defense as high as Gentry’s, and there’s little chance he walks as much as Gentry has
The wrench in my calculations was the replacement adjustment, but I still feel comfortable sticking with my estimates for his value. Perhaps a half-win higher? Just ballpark numbers for talent level; he’ll do better and worse than these I think. Just like Victorino isn’t a 5-WAR talent player, I don’t think Castillo has 3.7 WAR talent.
Even admitting the huge importance to walks and OB%, if he is a .738 OPS, 65-70 defense and 60-65 base runner, IMO he is better then every one of those 5 players and WAR will show this as well.
You said that Jennings has a bit more pop, but Jennings has only a career .401 slugging percentage, a lower slugging lately and a ISO less then the .162 you project for Castillo. Maybe you just over stated Castillo’s .430 slugging projection? I actually expect an identical OB% percentage as you, but thought he was more like a 400-410 slugging percentage. Which would help solve some of the difference we have in thinking what kind of a talent he is. He would be closer to a 2.5 WAR player if he had a 400 slugging.
As for the Victorino-Castillo point being kind of over rated by WAR compared to their true talent, I actually totally agree. However, I think all of these other OFers with great defense are over rated by WAR too, like Gentry and Cain. Which I guess is another topic all together. However, if Cain and Gentry get high WAR numbers, so will Castillo if he has 65-70 defense.
Anyways, thanks for the interesting scouting and video of Castillo.
All fair points. I definitely didn’t want the WAR numbers to be taken as gospel. I think his defense is going to be pretty good, maybe better than what others have projected. It seems like most of those 3+ WAR seasons from the players you brought up come from outlier defensive seasons, which is one reason I have trouble counting on that as a talent level for Castillo.
Underscoring all of this is my disdain for season-to-season defensive valuations. There’s a lot of luck involved with opportunities for defenders to rack up value, and it’s not nuanced enough for me to appreciate it. Maybe defensive replacement level should be separated from offense, but I’m still putting my thoughts together how I would improve on the current models.
I can’t disagree with you, but I also don’t think he’s a 3 WAR player. Maybe it’s just some old school bias toward offense that blinds me, but it just doesn’t feel right.
Thanks for the comments! If nothing else, it’s making me question/understand the replacement calculations better.
Thanks for a thorough and thoughtful analysis as well as the illustrative GIFs.
You reinforce my belief that at age 28 Castillo is not likely to by as productive offensively as 21-year-old Mookie Betts, who has an OPS of .812 as I write this and has shown an elite contact and plate discipline skills. I also think Betts has a swing that supports his strong numbers. And while Castillo no doubt has more batting practice power, Betts may very well have more functional game power because of his swing.
I’d also expect Castillo to be the better defensive outfielder because Betts is learning the position, though Mookie might be more valuable as a 2B defensively than Castillo is as an outfielder.
Needless to say, with the glut of outfielders in Boston, and with Betts and Castillo expected to play side-by-side once the AAA playoffs are done, the two will be compared.
What’s your take?
I am definitely a fan of Betts’ swing, and agree he will easily outproduce Castillo on offense, even in the power department. A lot of hitters have BP power resembling Castillo’s that never show it in games. I think it’s more a product of bat speed, since the pitcher isn’t supplying as much force and is throwing the same speed every pitch.
If I had to choose between the two I would take Betts no doubt, even if they were the same age with their current tools. Betts doesn’t have a great arm, but his actions are a lot smoother throwing and swinging, which I think makes it easier to see Betts staying consistently useful regardless of position.
Re the WAR projection, your .308 / .430 hitting projection is almost precisely MLB average for a CF (.326 / .396 this year), with OBP traded accurately for SA, one point for two. And average is 2.0 WAR above replacement per 150 games.
So I believe this scouting report is actually a 3.2 WAR projection. A .400 SA would knock it down to 2.7.
Makes sense to me. The WAR numbers are skewed low because of my misunderstanding with how the replacement and league adjustments fit in when I was looking for comparable skillsets in each department. Like I just responded above, 3 wins seems too much, so I could get behind something 2.5-2.9999 WAR as an estimate.
🙂
RHB’ers who hit a lot line drives at Fenway, especially to LF tend to get hurt a bit as many HR balls go for singles. It sounds like his HR’s when he hits them won’t be of the cheapie variety
If he has trouble with pitches down in the zone he is going to have trouble since the strike zone is dropping.
Good chance this guy is a Willy Mo Pena with a better glove and base running skills. However, time will tell. Definitely worth a gamble by the Red Sox here as they have so much cash to burn.
The projection numbers on this still bother me…but I think instead of rewriting what I said, I only wish I would have included ranges in some capacity. Kiley had some interesting insights in his Scouting the Hit Tool series, talking about how the grades on tools are roughly 50th percentile outcomes, with future tools representing something like the 75th range. I think my grades probably fall more in the 60-65th percentile of what I expect from Castillo. I think the error bars on this grade are rather large, not because I lack confidence in my evaluation, but because his skill set is very volatile by nature. I don’t see Adam Dunn-like consistency in his future. One season may be a 1-2 win stinker; the next could be a Victorino-esque 5 win season. I see the 1-2 win scenario as more likely to happen than the other.
I apologize for the confusion. I like the idea of putting my nuts out there with projections, so that will likely continue; it’s fun! I will certainly be more clear in the future, and will keep working to find ways to describe tools beyond the 20-80 scale.
Thanks for all the great comments!
