Crowdsourcing: Blue Eyed Players

Earlier this week, Josh Hamilton created some headlines when he claimed his eye color was the cause of his struggles during day games. ESPN found an optometrist who supports his theory, so maybe it’s not as crazy as it initially sounded. I immediately wanted to look at the data to see if other blue-eyed players had similar struggles in the day time, but realized that there isn’t exactly a comprehensive database of eye color for Major Leaguers.

But, the FanGraphs audience watches a lot of baseball (when they’re not staring at spreadsheets, anyway), and you guys have some observational powers, so I’d like to try crowdsourcing this. Here’s what I’m asking from you guys – in the comments, give us evidence of players who have blue eyes. Photos are probably the best option, but an article from a reputable source that references a player’s blue eyes probably works too.

If we can get a decent sized sample of players who can be confirmed to have blue eyes, we can look and see how they did in day games compared to night games, and see whether there’s anything to Josh Hamilton’s claims after all. Once we have a decent amount of names, we’ll crunch the data and report the results.

Go crowd go.

    • joser says:

      Actually, if the problem exists it might be almost the same for blue or green eyes. The optometrist in the linked article says as much.

      “Because of the lack of pigment in lighter color eyes, like blue or green eyes as opposed to brown, you get a lot more unwanted light and that can create glare problems,” Dr. Ison said.

      So maybe we’re just looking at brown vs non-brown irises. Though — assuming there’s anything to this at all — it very well could be more complicated than that. There are multiple genes responsible for eye-color, so one blue eye is not necessarily like the next, and if we’re talking about the fine line of distinguishing the rotation of the seams on an approaching baseball, slight variations might make all the difference.

        Actually I have a beard for three reasons 1) my wife likes them, 2) in my profession I can have a beard, 3) most importantly I am lazy and do not like to shave everyday. The fact that woman and children do not have beards never entered my head. Trimming once or twice a week rather than daily shaving is my number one reason.

    A quick and dirty control analysis would be to take African and Asian ancestry players and see if brown eyes are affected by day/night games.

    There are the occasional blue-eyes (or rather non-brown eyed) people of African or Asian ancestry, usually due to some Caucasian relative but these are fairly rare.

    By far the easiest way to filter the list would be to racially profile the hitters on the team you follow. It is pretty easy to tell in HD during a game what eye color they have if you freeze-frame an at-bat. Of course it does not help when they wear sunglasses that do not let you see the eye color.

    ESPN’s state page has a nice profile image, where for the most part you can make out the eye color.

    Quick and dirty analysis of 11 blue-eyes versus 11 brown-black eyes, using 2008-2010 OPS. Average of the 11 players day versus night. Overall both sets of players did a little better in the daytime. The non-blue-eyed players did +0.034 OPS better in the day, while the blue-eyed players did +0.012. But the standard error of the mean was 0.026 and 0.024 meaning that the variation between players was higher than the group differences.

    i.e. with only 11 samples there was no significant difference between blue versus non-blue.

    Brown-black eyes Day = .826 Night = .792 Day-Night = .034 St. Error mean = plus/minus .026

    I don’t think this methodology will accomplish much of anything – people are just going from memory so of course players who played longer, got more exposure, and were generally more famous will spring to mind. The blue-eyed rabble who came up for a cup of coffee, or wiped out after 200 big-league at-bats spread over 3 seasons, likely won’t show up in the sample.

    • Double D says:

      Yes, but those guys who played a lot and are stuck in our minds? They have more PAs to establish a trend for day/nite splits. The guy with 200 PAs in his career would have, what 50 day PAs, if he wasn’t on the Cubs and avoided domes? So I wouldn’t worry too much about it.

  34. JoeyO says:

    Although this is an interesting theory to explore, I feel it should be mentioned that the variables here are extreme and will likely make it near impossible to determine one way or another.

    We would almost certainly need to factor things in like Smog/Air-Quality, Fog/Cloud Cover trends, Temperature averages and Seasonal Variances among other aspects. Playing a September Day-Game in San Diego is quite different then a May Day-Game in Cleveland. Shoot, a Day-Game at PETCO is often drastically different then a Day-Game 100 miles up the Cali Coast at Dodger Stadium on the very same day. And a Night Game at Angel Stadium might be 80 degrees, where it could be 20 in Detroit…

    In the very least, a Day/Night Park-Factor baseline might be needed prior to delving into the Eye-color portion. For all we know its the very sunny, dry-heat in Texas that is the real factor – and a quick check of splits for the club does indicate it may be as well, as most years there is a fair size Day/Night split on the Rangers which can’t be all Hamilton

    • Robert says:

      Those things should have an equal impact on both blue-eyed and dark-eyed players though, correct? Therefore, if a difference between the 2 samples is observed, I’m not sure why the factors you listed would diminish the validity of the findings. I might be missing your point, though.

      Also, theoretically, if we were to gather a large enough sample, noise due to those factors should be washed out.

      Vote -1 Vote +1

      • JoeyO says:

        Yeah, all eye color players will be effected to at least some extent, but that isn’t whats important – whats important is the Day/Night Park-Factor for the individual cities.

        Like say in San Diego the sunny skies, better air quality and non-drastic Day/Night temperature changes means the average player doesnt see much of any Day/Night difference regardless of eye color; that’s then a fantastic environment to test the numbers on. But in say Philly where the smog is horrific, the weather can get drastic and temperatures can swing fairly far from day to night, you have a situation where all players might be better at night or vise-versa.

        Places where it is more likely to get extremely cold at night would probably produce higher day-time numbers on average. Higher smog would likely eliminate some sun glare but also possibly give everyone higher irritation/less viability. Higher cloud and rain probabilities likely decrease the day/night variance. Wet nights in West Coast cities should decrease power numbers, but also probably increase walk rates if pitchers have a harder time with slippage.

        Much like playing in Colorado 82 times a year is a boost to a players stats over a place like Oakland, the parks will have effects. And if you’re just taking random players from random teams and combining all their numbers regardless of the advantages their individual parks provide, then you are likely inadvertently skewing the results to an unknown degree.

        Know what I mean?

    As a Yanks fan, I looked up Derek, ARod, Gardner, Jason Giambi, Scott Brosius, Mickey, Maris and Paul O’Neill on BRef and all are better during the day (based on tOPS+) except O’Neill. O’Neill was the only other player I’ve heard mention that he prefers hitting at night due to light conditions. Ironically his numbers are pretty much exactly the same day versus night.

    Hamilton’s day/night split is huge, whereas all mentioned above have modest splits.

    I have always thought generally that there are daytime (early risers) people and nighttime (night owls) people, and that has more to do with Josh’s splits.

    Looking up splits might be misleading if you don’t know who was wearing sunglasses or special contacts during the day games. Bronson Arroyo, Brian Roberts, Mike Timlin and Joe Mauer are documented here:

    The lens have been in use since 2005, but have now been discontinued. Arroyo is still supplied with some sort of lens from Nike, I believe, but perhaps not something available to the general public.

    Aren’t blue eyes a prerequisite for “the good face,” and isn’t “the good face” a prerequisite for playing in the big leagues?

    By taking the transitive property of the good face into account and forming a simple syllogism, we come to the conclusion that all MLB players have blue eyes, and therefore will all struggle during the day.

    This explains why the Cubs haven’t won in 100 years.
