Extracting the Juice Out of Desmond Jennings

A lot of post-Manny/Damon signing analysis has declared Desmond Jennings the biggest loser of the day as it appears he is destined to start the season in AAA Durham. To be honest, this was a likely scenario before the signings, but the presence o Johnny Damon no longer makes it a short-term sacrifice for the benefit long-term game. Desmond Jennings has been our top positional prospect for a few seasons and has an incredibly bright future, but there are several good reasons from the team's perspective to have him in Durham for the near-term. Let's take a look at some of the common arguments for putting Jennings on the 25-man and then I will attempt to validate the reasons why it is preferable to have him in Durham.

1. Desmond Jennings has already played a full season in AAA and is one of the top outfield prospects in baseball. Leaving him in AAA any further can be discouraging and stunt his development.

Desmond Jennings would probably be the first to tell you he had a disappointing 2010 campaign. Deezy entered the season ranked as the sixth best overall prospect in baseball by both Keith Law and Baseball America. Jennings sprained his wrist in the Spring, and failed to build on 2009's momentum finishing with a AAA slash line of .278/.362/.393. Jennings has displayed a great glove, plate discipline and speed, but the power element has yet to blossom. Hopefully Jennings can build on these numbers in 2011 and earn a promotion to the big leagues, but there is plenty of room for development in AAA in the mean time. Injuries have been a concern about Deezy for years, and last season  did nothing to quell those worries.

We have heard similar concerns regarding stalling the development  of John Jaso (26/27), Matt Joyce (25/26), and Reid Brignac (24/25), yet when they finally got their chance they proved able to deliver with minimal growing pains and will now be around the organization for their peak years which leads us to...

Star-divide

2. Desmond Jennings turned 24 in October. Top prospects are usually in the big leagues right around now.

The Rays are a a very patient organization and with good reason. The Rays will have very few players stick around beyond their cost-controlled years; it's the nature of small-market baseball. Player salaries are under team control for the first three seasons (excluding Super 2s), after which the player becomes eligible for three years of arbitration which uses a guideline of 40-60-80% of the player's market value. Knowing that there is typically a six-year cap for individual players on the major league team, the Rays need to maximize each players time on the 25-man roster.

The great Mitchel Lichtman, co-author of The Book has done a lot of research into peak ages of baseball players finding that players peak at 27/28 years old. The question for optimal utilization can be answered by looking at the changes from each year before and after the peak.

If the aim is to try to time expected peak age optimization within the constraints of team-controlled years, then the first year of service time should be the 24/25 year old season (2011) or the 25/26 year-old season (2012). Jennings would be 30 or 31 heading into his ARB 3 year coming off his peak stretch, hopefully scoring the team a massive loot in exchange for a train that will likely be heading downhill. By waiting 30 days into the season the Rays will, they will save a year of team-control. If they wait 80 days or until the end of June,the Rays can avoid Super 2 status (adds a fourth year of arbitration eligibility),  yet still have his 2nd half contributions.

Contrast that to ghost of Rays past Delmon Young now age 25, who finished the season at 2.1 WAR, his first season worth a full win above replacement. At 25 years old there should be no shame in that, but he is already north of three years of service time and into his arbitration years. He will be a free agent for his 28/29 season. That's poor resource optimization. Nobody likes to have their prospects out of sight in the minors; shiny new toys are very exciting. Yet people will be outraged when BJ Upton is likely traded heading into his ARB 3 season next year which leads us to......

3. Gold glove left-fielder Carl Crawford just left in free agency. Wasn't Jennings supposed to be his tailor-made replacement?

Yes and no. In terms of exceptional glove work, yes. But Carl Crawford is a center-fielder playing in left. The Rays have been  blessed with having Upton and Crawford in the outfield at the same time. Crawford's bat allowed the Rays to play two center-fielders for years. However, shortstops, catchers, and center fielders are generally the toughest position players to replace. The Rays can find bats with slightly less glove to replace Crawford minimizing the damage because he played in a corner outfield spot. These guys typically mash. Finding an affordable replacement in center is a much more daunting task.

BJ Upton is the second-most expensive Ray to Johnny Damon and there is a very good chance neither one will be back next year. Enter Desmond Jennings, now a tailor-made replacement at a much tougher position to replace. Playing in center-field should also take a lot of the pressure of his bat as the expectations are greater in the corner, particularly if you are facing the task of replacing team legend Carl Crawford. Saving that year of service time hopefully assures the Rays of six more years of a premium position locked down under team control with a well-above average player.There might be some groans about trading Upton but the current front office can't be held accountable for the sins of the past regime. To the team's credit they have been masterful in having exciting replacements ready to ease the pain of losing fan favorites as they become more expensive. The Matt Garza trade is a perfect example. Jeremy Hellickson is able to step right in now as a top pitching prospect in baseball and the farm receives a sweet overhaul of exciting prospects while not surrendering competitive years.

Between Ben Zobrist, Matt Joyce, and Johnny Damon, the Rays should have their 2011 corner spots in pretty good hands. Those concerned about Damon's weak arm in left should feel better with potential defensive specialist Sam Fuld available off the bench late in games with the lead. Fuld is 29 and out of options, therefore there is no reason to be concerned about his service clock being wasted on the bench.  If Fuld isn't your cup of tea, there are a multitude of other possibilities afforded as a result of the Rays positional flexibility. The Rays can clearly communicate their plan to Jennings, show examples of prior successful debuts, and give him areas of his game to work on as they did with Jaso, Brignac, and Joyce. Hopefully knowing where he stands in the Rays plans can eliminate the guessing games and allow Jennings  to further blossom his game. Six years out the team will be much better off for it.

(H/T to FOTS  RJ Anderson for assisting with service time questions)

Nice post

Only part I don’t like is how there’s no in-house candidate for LF in 2012 and beyond, so I guess we look to FA or trade for that.

Brandon Guyer perhaps

  Very curious to see how he does at AAA building off his .344 .398 .588 at AA. He could play his way into the mix.

by sinkhole on Jan 24, 2011 9:04 AM EST up reply actions  

This is a good possibility

Guyer is another, if SRod doesn’t improve vs RHP this year, they may need a lefty bat to platoon LF with Zo. I actually think Zo might be in RF with Joyce in LF.

I was pretty disappointed knowing Deezy wouldn't be up on Opening Day

but after a weekend to mull it over, and this article giving some more fodder, it makes sense. Deezy got a taste of MLB life last year, let him hone his craft in AAA and when the time is right (the time is not now), hopefully he’ll turn from the #6 prospect into an every day baller.

  Jaso, Joyce, Hellickson and Dan Jo all joined the team late last year and were a big part of winning the East. Dez will lead the next wave when the dust clears. Our depth is gonna surprise the hell out of people when we need reinforcements.

The aging curve is very interesting

Do you think that, with PED testing, we are looking at the return of the pre-1980 curve? Anecdotally, there seemed to be more young player finding success the last couple years, and more older players getting hurt and/or declining (Jim Thome notwithstanding).

by nomoredevil on Jan 24, 2011 9:21 AM EST reply actions  

I've considered the point

but I suspect their are plenty of alternatives they don’t test for plus better nutrition and training available. After watching Burrell and Pena in a sample size of two, it makes you wonder about the curve at least for sluggers.

I think my favorite part of this

is the fact that even if Deezy lit the world on fire at the end of the year last year, and was projected to do big things this season, this FO would not alter its plan at all. It continues to amaze me how well they maximize long-term assets while sacrificing essentially nothing in the present. I, just like anyone, was extremely excited to see Jennings get a chance to play most days this season and I would be lying if I said I wasnt a bit disappointed. That being said, I sleep well knowing our FO is going to get the most out of every player in this organization while paying as little as possible for that production. Good stuff FreeZo, definitely paints a good picture of this whole situation.

Thoroughly enjoyed this one. Very little dispute that 24/25 would be the optimum season for full time call up.

These doesn’t take into account defense though right? Would you expect the curve to be shifted left somewhat?

Good to see you hit on a theme i've been touting a while

It really doesn’t matter when a Rays prospect hits the bigs, cause it is usually a ‘6 and out’ scenario

Not bashing the approach, just a matter of fact

Good grief, you keep missing the point

It does matter when they have 6 year windows. You want it to be their peak years, not too early.

Just thinking out loud here

But is the goal really to maximize each individual’s peak? Suppose this year, LF was the missing piece to a championship puzzle. Wouldn’t it make sense to bring up a kid a little early for the good of the team? Even if it hurt his own production?

Not that it relates to this year or this situation. Just looking at it holistically instead of each player in a vaccuum.

by nomoredevil on Jan 24, 2011 12:25 PM EST up reply actions  

Its a combination

But finding a one year stop gap to allow Jennings to develop in AAA was a very smart thing to do.

I think this was his point; he just didn't articulate it well. It doesn't matter about trying to get them up as early as possible, since we can let them wait and get more peak.

So we don’t need to worry about delaying prospects down in Triple-A for a while. And older prospects, like Chirinos, may be undervalued by other teams because of their age, but can be quite valuable for us.

I love Casey Fossum. Now try and take me seriously.

by Steve Slowinski on Jan 24, 2011 12:31 PM EST up reply actions  

Yup, totally. It just requires a different mindset in regards to prospects.

I feel like the traditional approach is always that sooner is better….the best prospects are up the earliest, so if a prospect is worth anything, they’ll be up in the majors fast. But that’s not how the Rays should do it.

Generally I like the idea of this post, and have thought about it myself, but it misses the underlying idea behind the concept of "stunting a guy's growth"

that underlying idea being that a player may be more (or less?) likely to maximize his potential if he plays at the major league level sooner than later. Ultimately, it’s a balancing act, and traditional wisdom also warns against bringing up a guy too early by focusing on some of the psychological aspects of coming up when one isn’t ready.

Ultimately, though, I think it would be maximally revealing if these age/peak performance curves separated guys based on several factors: 1) age when they come up. It is possible that a guy who comes to the majors at a younger age has a shorter learning curve and more quickly reaches his peak than a guy who comes to the majors at an older age. I’m not arguing that this is the case, but a look at what the data says would be useful. Of course we would have to try to separate out certain factors… 2) Considering point #1, we have to note that the guys who come up earliest tend to be the super-star once-in-a-generation talents, and their performances will likely skew any kind of curve. I wouldn’t doubt that a graph looking at all 20-yr old position players would look crazy and inconsistent with the rest of a graph. And this brings us to a third point 3) Generally, certain types of players might have different curves and rates of improvement at the major league/minor league level: pitchers vs position players, catchers vs infielders vs outfielders, on base guys vs. batting average guys, speedsters vs sluggers, future stars vs future “solid” players, or, as we saw above players from one era vs players from another. Of course, the more we parse things apart, some of the partitions being more value than others, the smaller our sample sizes become.
