David Robertson’s Heat Maps
Although there really isn’t a lot of data on Robertson to this point in the season, I do think his pitch location is worth noting. He seems to be nailing that outside edge vs. LHB consistently.
However, it’s right handed batters that are really coming up empty against Robertson this year; he’s faced 21 RHB and struck out 11 of them.

Robertson has thrown 106 cutters this season, recording nine strike outs and yielding five hits in 22 plate appearances. Batters are chasing the pitch out of the strike zone at a rate of 26.7%. Last season, his chase% on cutters was 19.3%.
Similarly, his fastball is getting batters to chase 31.4% compared to 20.3% between 2008 and 2011. Robertson has recorded eight strike outs on his fastball this season while giving up two hits in fifteen plate appearances. He’s actually relying on his cutter more as he’s thrown only 74 fastballs to this point. His cutter and fastball come in at roughly the same velocity (92.7 MPH and 93.0 MPH respectively since 2011). Batters might be finding it difficult to identify between the two pitches, resulting in his fairly high strike out rate to this point. I remember Russell Martin mentioning last season that Robertson’s cutter explodes at the end, much like Mo’s.
Robertson only started throwing the cutter last season; I can’t help wondering what part Mariano may have played in helping him develop the pitch.

Is the normalization consistent? Almost certainly is, just wondered about the tails being effectively suppressed when there are very few pitches/bin.
Interesting. I had wondered whether Mo tutored Robertson. Maybe yes, maybe no, but there have been plenty of articles throughout the years talking about how Mo will TRY to teach his cutter to anyone who asks—only they just can’t throw it.
Maybe Robertson really is the Son.
Heir to Mo. Book it.
Also, Pap blew another, to the Mets. Kid hit a 3R HR to break a tie in the 9th, in his first MLB at-bat !!
Maybe Robertson can close out the All-Star game this year.
Batters have a less than 50% chance of even putting the ball in play against Robertson? SICK.
PS, any reason we’re in Hawaii now judging by the time?
The best part of this it that he *seems* to be getting the walks under control.
If you could swap any reliever in baseball for Robertson (and they automatically took on Robertsons contract) would you?
I dont think I would swap him for anyone.
[8] I dare say that Robertson right now is the best reliever in baseball, so , no I would not. Also, High Socks.
Most importantly, everyone should watch this
The only guy I’d put in Robertson’s league is Mike Adams from Texas. But I still wouldn’t swap them. Adams is similar to Mo in that his primary pitch is a filthy cutter(thrown with a bit less velocity), but I just love watching Robertson pitch. There’s something cool about a guy with two plus-plus pitches making hitters look foolish.
[8] Since Aroldis Chapman is currently being used as a reliever, yes
On a more practical level, Robertson is pretty much the best, though I agree with SG about Mike Adams. I should also note that the three relievers on one of my fantasy teams right now are Robertson, Chapman, and Adams, so maybe I’m a little biased
Despite it being Verducci, I love this article about pitcher analysis…and not just because Robertson was featured.
When did Chapman learn control? I had no idea he was doing so well this year.
How interesting that this piece writes strikeout as two words.
Robertson is so much fun to watch.
Is the normalization consistent?
Yes.
How interesting that this piece writes strikeout as two words.
Damn spell check.
From the article:
“Alfredo Aceves, Yankees”
Oh, just rub it in.
[12]
The radar gun, for instance, measures only the speed of a pitch at a given point. But when it comes to fastballs, the battle between the pitcher and hitter is decided by time, not by speed: How long does a fastball take to reach the plate once it leaves the pitcher’s hand?
Isn’t the definition of speed how long it takes an object to travel a certain distance? Point in time is velocity. Perhaps I’m too demanding…
Mike, that’s the definition of speed. But the point the article’s making is that sometimes the DISTANCE, the “certain distance” you mention, varies.
