Ian Desmond is 0-for-14 with 10 strikeouts and zero walks against Craig Kimbrel.

I know, I know. Small samples, noise, predictive value and whathaveyou — I get it. Usually, it’s best not to read too much into batter-pitcher matchup stats. Sometimes, though, it’s clear that a certain batter just doesn’t stand a chance against a certain pitcher. Sometimes, it’s clear that a Craig Kimbrel can turn an Ian Desmond into a helpless puddle of mush in the batter’s box simply by standing on the mound.

What if I told you that, in rare cases, fielders could possess the same ability? What if I told you that, in early 2014, Andrelton Simmons learned he had such a power? That simply by taking the field, he could render Travis d’Arnaud completely and utterly powerless? Not only that, but that Simmons could actually control the game with his mind, so long as d’Arnaud was on the field with him?

* * *

The date was April 9, 2014. Spirits were high in the Mets’ clubhouse. The season was young. They’d shut out the host Braves in their home opener the night before. Young catcher Travis d’Arnaud had collected his first two hits of the season and scored a run. He hoped to build upon that success against Braves hurler Ervin Santana the next day. He strode to the plate, confident and unknowing.

This was young d’Arnaud’s first encounter with Simmons. The result was unexpected, yet also unsurprising. d’Arnaud had heard tell of Simmons’ skills. Now, he’d experienced them firsthand.

“What can you do?” d’Arnaud thought to himself. “Gotta tip your cap.”

In fact, as he lunged toward first base, d’Arnaud did tip his cap. It fell right off the back of his head and down to the Earth behind him. As the helmet hurtled toward the dirt, it eclipsed the print on the back of d’Arnaud’s jersey, momentarily displaying the word “dUD.”

This could be interpreted as foreshadowing.

No, we aren’t just going to do a leaderboard sort for best movement in each direction and call it a day. It’s a little bit more complicated to figure out the best changeups by shape and speed, mostly because it’s all relative. The changeup, as the name implies, functions off of the fastball, as a change of pace and movement. So we need to define anything the changeup does relative to the pitcher’s fastball.

Then we can do a sort and call it a day.

In order to define fastball movement, let’s just group together all of the fastballs thrown by a pitcher. It’s probably more nuanced than that; the concept of tunneling or sequencing shows that pitchers can pair their changeup with one fastball or the other for different results. But some of this comes out in the wash: by averaging movement across fastballs, their selection of different fastballs will weight the movement in the direction of the pitcher’s usage.

So then our x and y movement, and velocity, are defined against this average fastball for each pitcher. Using a minimum of 50 changeups thrown, and z-scores to sum up the values, we can get a list of best changeups quickly.

First, the relievers.

If you’re a team looking to add a significant piece to your roster, this is a pretty great winter to be a buyer. Unlike most recent free agent crops, this group of available players boasts both legitimately elite players and a host of quality mid-tier options. Especially for teams looking for starting pitching or outfield help, the supply of talent is unlike anything we’ve seen in a while, since the boom of early-career extensions has served to keep a lot of the game’s best players from reaching the open market.

Of course, supply and price are often inversely correlated, so when there’s a lot of talent available, it’s easy to conclude that teams will price-shop across multiple options, and we might see less inflation this year than we have in previous years. However, in this case, I don’t know that the increased supply of talent is actually going to lead a stagnation in salary inflation; in fact, I think there are some reasons to believe that we may see some significant spending, above and beyond what is already expected, by MLB teams this winter.

Ben and Sam talk about the best Barry Bonds facts with Jake Mintz and Jordan Shusterman of Cespedes Family Barbecue.

You’ve probably read about the role scouting played in Jarrod Dyson’s 12th inning stolen base in Game 5 of the World Series. The Royals knew that New York’s Addison Reed would slow his delivery in certain situations, and “a little shimmy with his hip” was going to be Dyson’s key to run. First base coach Rusty Kuntz shared that bit of info after the game, and I touched on it my recap.

Mark Topping, the team’s video coordinator, had a hand in the theft. As Kuntz explained, “Topper gives me 20 moves to the plate, and 20 pick-offs, for every pitcher.”

The video, Topping told me, allows Kuntz to “See if there’s any kind of tell; a guy moves his front front, or his toe, or whatever.”

The information is supplied via iPad, and it includes pitchers’ times to the plate. More than eyeball scouting is at play. Software is used to calculate the measurements, so they’re “extremely precise.” Read the rest of this entry »

There are few who doubt that, after finishing up his sixth season in Major League Baseball, Jason Heyward is a good player. Up for debate is precisely how good Jason Heyward has been during his career, and more importantly for whichever teams signs him this winter, how good Heyward will be moving forward. Attempting to measure defense with advanced statistics like UZR and DRS has its critics, and attempting to place a value on it can be difficult. Heyward has been an above average offensive player, incredible on defense, and heading into free agency a few months after turning 26 years old, provides few realistic players for comparison. Heyward will get paid. How much will he be worth?

Heyward’s main drawback, perhaps only drawback, as a player seeking more than $100 million is his lack of power. He hit 27 home runs in 2012, but recorded just 13 of them this year along with an isolated slugging percentage of .146, essentially league average. Combining average power with a low strikeout rate (14.8% in 2015) and a solid walk rate (9.2%), Heyward’s wRC+ of 121 puts him in the upper third in terms of the league’s hitters. Adding in 23 steals on 26 attempts and the rest of his baserunning, Heyward’s 22 runs above average on offense placed him within the top quarter of qualified hitters. Lacking in top shelf power, Heyward still provided solid numbers on offense, and after a disappointing start with he Cardinals, he hit .306/.375/.455 with a wRC+ of 130 from the beginning of May to the end of the season.

The lack of power does prevent easy comparison to most free agent mega-deals. The names brought up most recently with regard to Heyward are Jacoby Ellsbury, who got seven years and $153 million from the New York Yankees two years ago, and Carl Crawford, who received seven years and $142 million from the Boston Red Sox five years ago. While those deals might no look great now, age is a major factor. When Ellsbury was Heyward’s age, he had just completed his second full season. Crawford debuted young, but due to a team-friendly contract, he did not become a free agent until after his age-28 season, three years older than Heyward. Ellsbury, now 32, has been worth 21 wins since turning 26 while Crawford, 34, has been worth 22 wins over the last eight seasons. Solid production, that, despite some disappointing seasons mixed in.

Ben and Sam discuss free agents, qualifying offers, the Rays-Mariners trade, Alex Anthopoulos’ departure from Toronto, and Mike Trout Twitter.

In the first trade of the offseason, the Mariners shipped Logan Morrison, Danny Farquhar and Brad Miller to Tampa Bay in exchange for Nate Karns, C.J. Riefenhauser and outfield prospect Boog Powell. Dave Cameron covered the trade in depth this morning. I’m here to give you the skinny on Boog Powell according to my fancy computer math.

Powell split 2015 between Double-A and Triple-A, and hit a solid .295/.385/.392. Powell did an excellent job of controlling the strike zone: his 15% strikeout rate wasn’t too far from his 12% walk rate. He paired that plate discipline with a modicum of power and plus speed. He swiped 18 bases last year, and has primarily played center field in the minors.

Based on his 2015 season, KATOH pegs Powell for 4.7 WAR through age 28, which makes him roughly the 80th best prospect in KATOH’s eyes. This was a sizable step up from his 2014 forecast of 1.5 WAR. Below are his statistical comps, which were generated using Mahalanobis distance calculations. Read the rest of this entry »
