Raul Mondesi's 2013 season and what to make of it

Could the Royals be so lucky as to have their own Lindor? - Kelley L Cox-USA TODAY Sports

We talk about performance in terms of age relative to level, but how does Raul Adalberto Mondesi's 2013 campaign measure up to his fellow wunderkinder?

Raul Adalberto Mondesi hit below league average this year.

Sure, it was only 6% below-average, but he didn't tear the cover off the ball.

Some are unimpressed, citing below-average numbers as cause for trepidation. Generally speaking, an approach with trepidation is the best course, as planning parades four years out based on projections of prospects in A-ball doesn't really work out that well. This we know.

Back to Mondesi, though, it is probably instructive to look at what he did in comparison to his peers. After all, we're talking about a kid who spent the whole season in full-season ball and didn't turn 18 until the end of July. That's a real 18, by the way. There need not be any speculation as to what his real age might be what with him having been born in the US and all.

We all know who Mondesi is, but maybe Brendan Fraser's character in Blast from the Past just got connected to the internet and overheard the guys in the baseball card shop talking about the kid. So Adam, if you don't know who Raul Adalberto Mondesi is, here goes. As a slick-fielding shortstop who was playing against competition that was the average age of 21.6 years old in his Age-17 season, he had a .312 wOBA and a 94 wRC+. He was playing against guys almost four years his senior and holding his own at the plate while playing a premium position.

For comparison, the position players who were playing their Age-17 season in the Sally League were as follows:

Player Pos DOB AVG OBP SLG wOBA wRC+
Raul Mondesi SS 7/25/1995 .261 .311 .361 .312 94
Carlos Tocci CF 8/23/1995 .209 .261 .249 .245 50

That's it.

Since Mondesi does just qualify as an Age-17 player (the cut-off is June 30/July 1), let's include Age-18 players in the Sally, counting any players, full season or not:

Player Pos DOB AVG OBP SLG wOBA wRC+
Ronald Guzman* 1B 10/24/1994 .272 .325 .387 .330 106
Nomar Mazara RF 4/26/1995 .236 .310 .382 .322 101
J.P. Crawford** SS 1/11/1995 .208 .300 .226 .262 62

*49 games | **45 games

Let's extend it to the Midwest League.

Age-17: Justin Williams - LF (3 games) - 8/20/1995 - tore up rookie ball, no reason to post terrible slash from three games

Age-18:

Player Pos DOB AVG OBP SLG wOBA wRC+
Andrew Velazquez* 2B/SS 7/14/1994 .260 .319 .336 .307 87
Dorssys Paulino SS 11/21/1994 .246 .297 .349 .300 83
Anthony Santander** RF 10/19/1994 .242 .303 .370 .313 91
Carlos Correa SS 9/22/1994 .320 .405 .467 .400 147
Carson Kelly*** 3B 7/14/1994 .219 .288 .301 .280 69
Orlando Arcia SS 8/4/1994 .251 .314 .333 .303 84

*65 games | **61 games | ***43 games, demoted to NY-Penn League in June

That covers every prospect in full-season low-A ball this year within a year and three weeks of Mondesi's age. In 2013, there were twelve total position players who stepped on the field in the Sally League and the Midwest League combined who were in their Age-17 or -18 season. If we count the three games Justin Williams played, he was the third-youngest player to step on the field in A-ball.

Of all of the listed players, only two corner/bat-first prospects and one of the game's best prospects, Carlos Correa, were better at the plate. One of the two corner prospects only amassed 49 games at the level, starting the season in extended spring training.

That's just one year though.

Going back to the 2005 season, the following position players were no older than 18 through their whole full-season debut and played a full season (bold players were in their Age-17 season):

2012:

SAL - Rougned Odor 96 wRC+;

MWL - Francisco Lindor 102 wRC+

2011:

SAL - Jurickson Profar 142 wRC+, Bryce Harper 164 wRC+ (promoted straight to AA in July), Gary Sanchez 122 wRC+, Delino DeShields 78 wRC+ (misses cut-off by two weeks);

MWL - Cheslor Cuthbert 114 wRC+ (5/20 call-up), Ronald Torreyes 146 wRC+ (misses cut by three days)

2010:

SAL - Jonathan Singleton 145 wRC+, Domingo Santana 86 wRC+ (only 49 games played, but also barely missed the cut-off for 2011), Christian Bethancourt 70 wRC+ (missed the cut-off by four days);

MWL - Chris Owings 108 wRC+ (misses cut-off by three weeks, also missed last two-and-a-half months with injury), Mike Trout 173 wRC+ (misses cut-off by three weeks, promoted to high-A on 7/9)

2009:

SAL - Leury Garcia 68 wRC+, Wilmer Flores 83 wRC+, Jefry Marte 76 wRC+;

MWL - Avisail Garcia 73 wRC+ (May call-up),

2008:

SAL - Angel Villalona 107 wRC+, Jesus Montero 143 wRC+, Giancarlo Stanton 169 wRC+, Freddy Galvis 70 wRC+, Francisco Pena 92 wRC+, Oscar Tejeda 83 wRC+, Freddie Freeman 150 wRC+ (turned 19 twelve days after the season ended), Michael Almanzar 53 wRC+ (only 35 games, played in SAL to start 2009, but was demoted to NYPL), Matt Dominguez 137 wRC+ (missed the cut-off by three days);

MWL - Engel Beltre 101 wRC+

2007:

SAL - Francisco Pena 49 wRC+, Juan Lagares 56 wRC+, Billy Rowell 105 wRC+ (5/23 call-up);

MWL - Carlos Triunfel 107 wRC+ (promoted to high-A 5/28, 83 wRC+ after promotion in 50 games), Juan Diaz 67 wRC+ (6/5 call-up), Alex Liddi 97 wRC+ (misses cut-off by about two weeks)

2006:

SAL - Elvis Andrus 94 wRC+, Jose Tabata 127 wRC+, Fernando Martinez 150 wRC+ (split season between low-A and high-A, 78 wRC+ in high-A);

MWL - Allan de San Miguel 72 wRC+, Justin Upton 117 wRC+ (misses cut-off by about ten days)

2005:

SAL - Alcides Escobar (no wOBA for 2005 minor league stats, .271/.305/.362)

Not surprisingly, there are a lot of Major League regulars among the 17- and 18-year-olds. Looking at the list of players, Mondesi (and Carlos Tocci) is the first Age-17 player to spend an entire year in full-season ball since Wilmer Flores did in 2009.

In looking to compare Mondesi against the other Age-17 players who spent the whole season in either the Midwest League or the South Atlantic League, Mondesi ranks thusly in terms of wRC+:

  1. Jose Tabata - 127 wRC+
  2. Angel Villalona - 107 wRC+
  3. Elvis Andrus - 94 wRC+
  4. Raul Mondesi - 94 wRC+
  5. Wilmer Flores - 83 wRC+
  6. Carlos Tocci - 50 wRC+
  7. Francisco Pena - 49 wRC+

Of the partial season guys, both Triunfel and Martinez split their seasons between low-A and high-A. They both performed well enough to rank above Andrus and Mondesi with their stints in low-A, but their turns in the next level up were not as impressive with Triunfel sitting at 83 in 50 games and Martinez chucking in a 78 wRC+ in 28 games to go with his 150 in 45 low-A games.

Of those players, Tabata is a roughly 1.0 fWAR player, and Andrus has been worth 16.0 fWAR over his five-year career, though the bulk of the value is tied to his defense. As for Villalona, a murder charge in the Dominican Republic derailed his development for two years. He is back in the saddle, but it's hard for the first baseman to be used as a point of comparison for Mondesi. Flores returned to high-A two separate times after his mid-2010 promotion, but his past two seasons have given cause for hope. It's too early to say much of consequence on Tocci. Pena is a defense-first catcher and new Royal.

There is probably relatively little that we can learn about Mondesi through looking at all of the prospects who met the criteria above, other than to give us a rough estimate of the caliber of prospects that Mondesi finds himself among. There is, however, some anecdotal value in looking at prospects with similarities in both position and profile.

It is tempting to look at fellow middle-infielder Rougned Odor's 2012--which was very similar to Mondesi's 2013--and then what he did in 2013 and dream on what Mondesi's 2014 could be, but that's mostly going to be anecdotal wishcasting. The versions of Andrus and Odor seen in their first stints in full-season ball were pretty similar to what Mondesi did. Francisco Lindor, who was roughly eight months older for the level in 2012 than Mondesi was in 2013, is another highly-touted shortstop whose raw numbers in low-A ball weren't dissimilar from Mondesi's. He, too, took the next step at high-A.

Those three players were the closest comps positionally and offensively (with Escobar probably being in the mix) of the 17- and 18-year-olds. Andrus was the youngest relative to level, having about a month on Mondesi. Lindor was the oldest. If he can be somewhere between the three of them offensively, and given his profile there is definitely a decent shot at this happening, it doesn't take much imagination to see Mondesi rendering Alcides Escobar--or better yet, Mike Moustakas, not unlike the Orioles' phenom Manny Machado, who was almost precisely a year behind Mondesi on the development curve before making the leap straight from AA-Bowie to the Majors late in 2012--superfluous and possibly slotting in as a ~3.0 WAR player.
