When Good Stuff Goes Bad

While 2017 was the year of the dinger, it also looks like it was the year of velocity. Has baseball changed (both the sport, and the physical ball itself)? The signs point to yes – but on the pitching from, the importance of velocity has never been higher. Exhibit A:

That’s not average. That’s not maximum. That’s … the slowest. Let’s borrow a little bit of math from the documentary “Fastball” to just put into context how crazy this is.

PITCHf/x Forensics: Zach Britton

Hot off the press, the world’s best relief pitcher has been sent to the Disabled List with a dreaded forearm strain. A strain, for those of you not familiar, is the tearing of a muscle or a tendon. This is a big deal in the forearm, particularly for a pitcher, because these muscles are the ones that protect the UCL during the pitching motion.

We are all familiar with the performance Zach Britton put out in the 2016 season – arguably, one of the most dominant relief pitching performances of all time. What was happening under the hood to lead to this injury?

PITCHf/x Forensics: Rich Hill and Blisters

Pitch forks have emerged, and rage has exploded over the most recent Rich Hill trip to the disabled list – once again, for a blister. Hockey fans gearing up for the playoff run scoff, stating how their sport has players who take slap shots to the face and return in the same game – blisters? Those are a sign that baseball players are weak, pampered, and fragile. Why do blisters keep forming on Rich Hill’s fingers? What are the implications for changing his style that could prevent blisters from occurring all together? Why can’t Sidney Crosby grow a beard? Let’s get into the answers to these questions.

All of pitching revolves around applying the appropriate amount of pressure to specific areas at ball release, and causing the ball to spin about a certain axis. This pressure applied along the seams, generates friction, and spin on the ball. More friction? More spin. That’s why pitchers try the ol’ Icy Hot trick to get a better grip on the ball, and throw funkier pitches. Sorry if I got most of my pitching knowledge from Rookie of the Year – I flamed out as a player in High School.

PITCHf/x Forensics: Matt Harvey and Thoracic Outlet Syndrome

A lot was expected from Matt Harvey and the New York Mets starting rotation in 2016, but aside from the Norse God of Thunder, the season was a bit of a let down (to say the least). Having fully recovered from Tommy John Surgery, and a consequent missed season in 2014, Harvey missed the end of the 2016 season when he was diagnosed with Thoracic Outlet Syndrome and opted for season-ending surgery. Unless you’ve been living under a rock, chances are baseball fans know what Tommy John Surgery is, and where the ulnar collateral ligament resides. A lot less is known about Thoracic Outlet Syndrome, so let’s dig in.

FrankenStuff: Combining Stuff with Tunnels and Command Metrics

When you watch football, it’s very clear by body type, what position a player likely plays. Are you 6’5 and 320lbs? That’s more than likely a lineman. 5’9 and 210 lbs? Chances are, you’re a running back. Baseball is a lot different – Marcus Stroman (5’8, 180lbs) and Chris Young (6’10, 255lbs) play the exact same position. Chris Sale (6’6, 180lbs) and Bartolo Colon (5’11, 285 lbs (sure… I believe you)) also play the same position. There aren’t too many times on the gridiron where a 100lb weight difference will line up against each other!

The point I’m trying to make, is with such huge variances in body shapes and sizes, there are many different ways to skin a cat. Marco Estrada (of 89 mph fastball fame) was massively more successful than Joe Kelly (punching a fastball in the high 90s, and over 100 mph). Pitchers of all shapes and sizes (of body and fastball) find ways to succeed. The question is – when you don’t have the clearly obvious advantage of that big fastball, how do you get major league hitters out?
