What if Eloy played DH full-time?

The debate: Would the White Sox be better off if their rookie slugger did not play defense? | (Clinton Cole/South Side Hit Pen)

Last year, when explaining why Eloy Jiménez was not being promoted to the majors, Chicago general manager Rick Hahn said that the White Sox were not trying to develop a DH. While Jiménez playing adequate defense in left field is the ideal outcome, he is off to a slow start to his career defensively. So, how much would his value change if he never played defense?

Value stats like WAR account for differences in defensive positions, so we should observe the position adjustments for left field and designated hitter. As one might expect, both positions are less valuable than average, but left fielders, obviously, have a greater defensive value. The corner outfield positions are not as premium as say, shortstop or center field, while designated hitters are, well, designated hitters.

Take David Ortiz’s 2016 season, in which he played 140 games at DH and only one at first base. His defensive value for that game at first base was negligible. Throughout the season, the vast majority of which occurred with Ortiz at DH, Ortiz was 15.2 runs less valuable than an average player defensively. That number has two components: defensive performance (Ortiz was 0.0 runs above average in the only game he played defense) and positional adjustment (Ortiz was -15.2 runs above average, or 15.2 runs below average). Had Ortiz played a full season of 162 games, his positional adjustment at DH would have been -17.5 runs above average. By contrast, left fielders get an adjustment of -7.5 runs per 1,458 innings, or 162 games. All of these numbers are courtesy of FanGraphs.

So, for Jiménez to be more valuable as a left fielder than as a designated hitter, he needs to be better than 10 runs below average per full season. As of August 24, Jiménez is barely failing to break that threshold. He has played 731 innings of defense, all in left field. In those innings, his defensive performance has earned him a rating of 5.3 fielding runs below average. If we extrapolate that to a full season, Jiménez would be 10.6 runs below average as a left fielder.

It is no secret that Jiménez has struggled defensively. According to Baseball Savant, he has made 12 catches fewer than an average outfielder would have made. Only one player (Domingo Santana of the Seattle Mariners, with 13 catches below average) is behind him. Jiménez also has had trouble getting to line drives in the gaps, which sometimes has resulted in hitters taking an extra base (singles to doubles, doubles to triples).

Despite his struggles, however, Jiménez’s value this season would only be slightly better if he was playing DH. Going forward, the solution is to continue developing Jiménez’s abilities in left. As frustrating as he has been to watch playing left field, it is mighty difficult to be worse than 10 runs below average over a full season, and Jiménez is barely on pace to do that. Fielding will probably never become a strength of Jiménez’s game (and if it does, make way), but it does not have to be. Jiménez’s defense will develop to a point where he is consistently more valuable in left than as a DH.

One counterpoint is that the White Sox will ideally have multiple corner outfielders whose defensive abilities are better to Jiménez’s if/when they are in the playoff hunt. However, that is far from a lock:

  • Jon Jay, 34, is on the worst pace of his career defensively in terms of runs above average. Jay has only played 362 innings in the outfield, so extrapolating might exaggerate his struggles, but he is on pace to be an abysmal 25.7 runs below average over 1,458 innings (mercy). (Jay will be a free agent at the end of the season, and should not be on the 25-man roster next year.)
  • Ryan Cordell is a safe bet to be better in left than Jiménez, but he is probably not worth a spot on the roster, either, as his hitting is not up to par. As a result, Cordell has been below replacement level overall.
  • Adam Engel is a good defender, but if he is on the roster, the Sox should have him in center to maximize his defensive value — he has played a grand total of one inning outside of CF in the majors. Engel’s hitting has never been his strong suit (his 71 wRC+ this season is his career high, so if Engel is not playing great defense in center, then he isn’t worth a roster spot on a contending team).
  • Luis Robert is a beast, but again, ideally a center fielder.
  • Leury García fits the bill, but the White Sox only have one more year of control for him, and he is not exactly a cornerstone of the rebuild.

With the current roster and farm system construction, it is hard to see multiple internal corner outfield options with solid defense (players who are worth a roster spot, anyway). Pleasant surprises from the farm system (currently hard to come by in this organization) and free agent signings could solve this issue. But, even in that case, it would be best if Jiménez was serviceable in the outfield because of the importance of depth. If the White Sox find themselves with multiple useful corner outfielders with better defense, great. But, injuries occur, and if one of those theoretical outfielders gets hurt, we would rather not dread watching Jiménez as he runs out to replace one of them in the field.

Now is not the time to punt on Jiménez’s defense. As the former No. 3 overall prospect, Jiménez is vital to what the White Sox are trying to do in the next few years, and improving his defense could go a long way.

A season by a left fielder that should be an attainable goal for Jiménez’s prime is Matt Holiday’s 2012 campaign. That year, Holiday slashed .295/.379/.497 with 27 homers, good for a 140 wRC+. Despite being 2.8 runs below average as a defender in a non-premium position, Holiday was a 4.6 WAR player thanks to his bat. And even if Jiménez falls a bit short of what Holiday pulled off, there is nothing wrong with having a 3.5 WAR guy who sends pitches to Mars as one of the best players on a contending team.

  1. I’m happy to go out on a limb and say that Jimenez is eventually (I think by the end of next season, if not a little sooner) be an adequate, if no more, LFer. He shows a solid ability to improve, even if he takes little steps back now and then, and he appears to be willing to happily work hard to do so. He pretty obviously loves playing baseball and that’s the key ingredient to be willing to do whatever he needs to get better. I don’t think he’ll “need” to be a DH until a solid-hitting LFer emerges from the minors. It’s painful to watch sometimes, but I don’t think it will be forever.


  2. Assuming what Jose has said is true and the Sox are bringing him back it needs to be with the understanding that he is going to be the full time DH, he’s brutal at first base. In that scenario unfortunately, Jimenez would have to stay in left field continuing to be a hazard to his health and the health of his teammates in my opinion.


  3. I am not sure Jimenez can DH. What I mean is, I’m not sure he’d be comfortable in that role, and he may consider himself a failure. Then again, I don’t know if he can be decent in left field; he may be another Kyle Schwarber. We’ll just have to see what happens next year is all.


  4. Hopefully he can man LF because we may have some other options at DH. Maybe Mercedes until Vaughn shows up. I do not want to be depending on some AAAA outfielder next year! Tired of that 7 year revolving door. Any great shortstops available? Eloy LF, Robert C, Anderson RF… he has the arm for it.


  5. This is a really good, well-researched article! Being the optimist that I am, I would like to see Eloy improve over the offseason to be in LF permanently. I think that he has the capability to do so, and I don’t think he should move to DH unless it is an absolute last resort. Plus, Abreu might occupy the DH role after the 2020/2021 season.


  6. I’m really sorry I looked this up, but in Kyle Schwarber’s worst season by far as measured by dWAR, he was -1.4 in 129 games in 2017. Eloy is already at -1.4 in 93 games. Much as we may all love Eloy, for good reason, unless he turns into Alex Gordon in the next month, getting to be Schwarber defensively next season will be a giant step up.


    1. I don’t have a problem with anything you said so no worries, haha. If Eloy develops into the hitter we envisioned when he was crushing the ball last year in the minors, he might not even need to match Schwarber’s defensive value to enter 2012 Matt Holiday territory.
