Quick Visuals: A Look at Evan Longoria's Sweetspot(s)

Does this get your attention?

Longo_run_value_heat_map_contour_medium

Yes, RZ has finally pulled through and brought DRaysBay its very first "heat map"! Taking a cue from Jeremy Greenhouse of Baseball Analysts, here is my own short version of a visual scouting report that JG has done here and here (this counts too). My first subject will be everyone's favorite 2010 AL MVP candidate, Evan Longoria.

Looking at that colorful first graph, the color bar shows that anything not dark blue is positive run value. Focusing on the inside the strike zone, there are two notable sweetspots that Longoria seems to possess. Up in the zone and over the middle part of the plate, and just a little in from the middle of strike zone. This seems right considering where his home runs have been located.

Star-divide

Longo_run_value_heat_map_with_homers_medium

The majority his home runs are clustered almost perfectly in his two sweetspots. Beat the zone low and away and you should avoid the home run (sorry Longo).

I'm terrible, as some of you hawk eyes are wondering what that black circle was in the first graph. That is a contour line of his 50% swing rate meaning he swings at least half of the time at pitches inside that particular location. A little futher inside than what I expected but I assume that might be typical of most hitters with similar overall swing rates.

Although I am unable to produce the color coded charts for release points and movements as Greenhouse did, I will just settle for run value by initial pitch velocity.


Longo_run_value_by_velocity_medium

Longoria handles 90 mph pitches quite well in fact yet struggles somewhat with pitches between the mid-70s to mid-80s, which are most of the curves and changeups he sees. Although struggle is a strong word since the line barely gets into the negatives. Also note that I forgot to omit intentional balls, which constitute most of those sub 70 mph pitches.

Now moving away from the pitch f/x, I saw the conventional media recently compared Longoria to Orioles legend Cal Ripken Jr. and their similar statistics for their first two seasons in the Majors. No disrespect to Ripken, but somehow I don't feel comfortable with this comparison.

Ripken was average or slightly above average in wOBA for 17 of his 21 seasons played. But Ripken had his value in defense and EAA (extra attendance added). I'm sure Longoria can definitely outperform him in two of the three categories.

Awesome!

Longo loves him some inside heat. I’m guessing his 50% line goes outside the zone on the inside pitches because he loves them so much…can’t help himself but expand the zone a bit there.

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

Please please please

Tell me how you did the heat mapping. I tried for like a month and couldn’t get it.

Is this from the batter's POV or pitchers?

Also, why is way out of the zone in red?

This is pretty damn interesting, good stuff.

As you can always expect come from behind victory is when you least expect it.

Catcher's POV.

Dunno about the red…wondering the same thing. Apparently Longo getting hit in the head would score us lots ’o runs.

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

Maybe it's a halo of awesomeness.

I should mention it is catcher's POV

As far as the red goes, it is impossible for pitchers to get a strike there (negative RV) because it is essentially a HBP or a ball. It might be the approximate location of where his elbow pad is.

I just always assumed this was his sweetspot

ok. so after a bit of reading

about run value (this piece as well as the links posted, I think I understand it. Maybe I have understood what I read but am wrong about how I’m applying it to this map?

My question is about the scale of the map — it seems high to me?? It seems high that the ‘coldest’ point on the map represents a .10 decrease in run value. Is that all an individual strike is worth or is Longo just that awesome? or maybe I only think I understand?

awesome map, by the way. I love new ways to look at data. especially when they turn out to be pretty pictures.

by proveyrdifferent on Apr 17, 2010 11:30 AM EDT reply actions  

The scale should represent the likely run value for that particular location.

I believe it is suppose to be that high just because Longoria is that good. I’m sure if I took a really bad hitter or bad season, the scale would be inverse.

Here is a link discussing run values specificly for pitch f/x data.
