Crowdsourcing MLB Broadcasters, Part 2: The Central

Here at FanGraphs, we devote a lot of time to analyzing baseball. I flatter myself to think that our analysis, in some cases, helps shape the way you consume the sport. Measured in that way, however, we fall far short of the influence that your local broadcast of choice exerts. We may grace your brainwaves for a handful of minutes every day, but every time you watch a game on TV, the announcers are granted three hours to shape your view and enjoyment of the sport.

In fact, I would venture that no one group contributes more to your enjoyment and understanding of baseball than your most frequently-viewed broadcast crew. Despite that, it has been over four years since we last compiled a ranking of broadcast groups. Starting yesterday and continuing until tomorrow, we will post a series of surveys, one for each major league franchise. We will then use the results of these surveys to compile a comprehensive fan-based ranking of all television broadcast crews.

When you peruse the section for your team or teams of choice, you will find a link to a poll. That poll covers three categories, as well as an overall ranking. In addition, there is a separate space for any additional comments you would like to make. The eventual ranking of broadcast teams will be quantitative, but I will include relevant comments from this section in my writing of those rankings. Read the rest of this entry »

Jeff Mathis Can’t Catch a Break

Allow me to present you with assorted statistics from two players. They aren’t exhaustive, of course, and I’m trying to mislead you, but still:

Two Mystery Lines
Batter Barrel% Hard Hit% xwOBACON Max EV (mph)
Player A 7.7% 43.4% .375 108.5
Player B 7.7% 41.0% .382 104.1

Batter A looks a little bit better. He hit the ball hard more frequently and topped out at a higher exit velocity. Player B had a better xwOBACON — a mouthful of letters that simply means using xwOBA to measure a player’s quality of contact — but I think I’d take the hard hit rate and maximum EV of Player A anyway.

Here’s a further wrinkle: both of these players are, by reputation at least, among the best defenders at their respective positions. Player A is the better defender relative to his peers — he’s won five Gold Gloves to Player B’s zero — but Player B plays a position 20 runs up the defensive spectrum, meaning he has provided more defensive value per plate appearance in his career than Player A. Who would you rather have had on your team in 2020?

From these statistics — and specifically these statistics — it’s not exactly obvious. You might have a leaning one way or the other, but it can’t be more than a 60/40 decision. That’s not to say that you would have a tough choice going forward — Player A just turned 28, while Player B will turn 38 before the start of the 2021 season. Also, you don’t actually get to pick which one to add to your team, because Player A is under contract for next year. You could totally add Player B, though: he’s a free agent after a two-year run with the fifth team of his major league career.

Enough with the blind nonsense: Player A is Mookie Betts. You should have taken him! Player B is Jeff Mathis, frequent butt of incompetent-hitting jokes and widely reputed to be one of the worst hitters of all time. Sounds like we’re going to need to do some further digging.

Pondering a First Inning Mystery

You’ve heard of home field advantage. It’s simply a part of sports, like gravity or Tom Brady being competent and obnoxious. Here’s a dirty little secret, though: A decent chunk of home field advantage is actually first-inning advantage. Here, take a look at how home and away batters performed in the first inning and thereafter from 2010 to ’19:

wOBA Differential By Inning
Inning Away Home HFA
1 .318 .340 .022
2 .304 .314 .010
3 .311 .322 .011
4 .323 .330 .007
5 .314 .330 .016
6 .319 .329 .010
7 .308 .317 .009
8 .302 .308 .006
9+ .296 .297 .001

The first inning has the biggest gap, with only the fifth coming even close. It’s a consistent effect year-to-year, and it’s a big deal: A 22-point edge in wOBA works out to three-quarters of a run per game, which would work out to roughly a .570 winning percentage, significantly higher than the actual edge. If you could bottle that edge and apply it to every inning, baseball would look very different.

This isn’t some novel effect I’ve just discovered. It’s well-established, though I’ve never seen a completely satisfactory explanation for it. Could it be that the home team’s defensive turn in the top of the first warms them up for their turn at bat? Maybe! One counterpoint here: Home DHs have a 20-point wOBA advantage on away DHs in the first inning, then only a six-point advantage thereafter. Maybe it’s not that, then.

A theory that makes more sense to me is that home pitchers have a unique advantage in the first inning. In that inning, and that inning alone, they can exactly predict when they’ll be needed on the mound. Have a perfect warmup routine? You can finish it just before first pitch, then transition directly to the game. Visiting pitchers are at the mercy of the game. Start too late, and you won’t be ready in time for the bottom of the first. Start too early, and an extended turn at the plate might leave you cold. Read the rest of this entry »


The All-Defense Free Agent Gambit

A nice generic platitude is that free agency gives you a chance to completely remake your team. That’s an aspirational vision, but I mean, come on. Free agency gives you a chance to sign a really good player, or a few okay players, or even Daniel Descalso (I kid, Cubs fans, I kid).

In reality, completely remaking your identity mostly doesn’t happen. Teams don’t generally overhaul their image in free agency; they add pieces around an existing core they’ve carefully shaped. If they’re lucky enough to land a superstar, they’re at the mercy of fate as to which superstar is available; if you want to sign a 6 WAR third baseman this year, well, keep looking.

It only mostly doesn’t happen, though. This year, I think there’s a rare chance to actually change the identity of your team in free agency. More specifically, I think teams should look at turning their squad into a defensive powerhouse. That’s mostly not a one-year undertaking, but this time, I think it is.

The first key factor that makes this strategy workable is an accident of personnel. You might have heard of the best defensive shortstop on the market. Indeed, Andrelton Simmons is one of the best defensive shortstops of all time, period. His range, arm, hands, and baseball instincts are all off the charts. Whichever team signs Simmons will immediately have one of the best defenders at the position, a down 2020 notwithstanding.

Simmons is the best infield defender of the past 10 years. The best defensive second baseman over that same span isn’t quite so clear, but Kolten Wong is certainly near the top of the list. He’s been one of the very best defenders at the position in each of the last three years, including a blowout 2018 that, naturally enough, is the only year he didn’t win a Gold Glove despite outstripping his other two seasons by every metric.

With two strokes of a pen, a team could sign Simmons and Wong and have the best up-the-middle defensive infield in the game. I’m exaggerating slightly, of course: most contracts need more than one signature, and most names need more than a single pen stroke to sign. I’m certainly not exaggerating, however, when I say it would be the best defensive combination. Whatever their other shortcomings, Simmons and Wong look better than any other pairing in the game.

Nicky Lopez, Caught Red-Handed

In the 1980s, the stolen base was king. Rickey Henderson and Vince Coleman were absolute terrors on the basepaths, giving pitchers no time to breathe. They each stole 100 or more bases three different times, with Henderson’s 130-steal season standing atop the single-season leaderboard, unlikely to ever be matched. They were hardly the only speedsters, either; Tim Raines stole at least 70 bases in six straight seasons, for example.

That need for speed made a delicious baserunning omelet, but it also cracked its fair share of eggs. In 1980 alone, players were caught stealing 1,602 times. That’s the cost of doing business when you’re going to steal so frequently. If you only attempt to swipe a bag in the 50 best spots to run in a given year, you’ll be successful at a higher rate than if you go 150 times.

As baseball tactics changed, the steal lost favor. First, home runs decreased the value of steals. Put one over the fence, and it doesn’t matter which base the runner was on. Second, teams started to better understand the value of avoiding outs. The exact math varies based on context, but as a rule of thumb, you need to steal three bases for every time you’re caught to provide neutral value. Succeed less than 75% of the time, and you’re costing your team runs in expectation.

These two effects led to a predictable change in behavior. Stolen bases have been in steady decline, while success rate on the attempts that remain heads inexorably higher. In 1980, the average game featured roughly 1.5 steals, and the league-wide stolen base success rate was 67%. In 2020, there was less than one steal per game for the second straight season:

On the other hand, the success rate crested 75% for the first time:

Is this a good development? It all depends on your point of view. Steals are exciting, whether they’re successful or not; they punctuate the stilted and ponderous pace of the game with a jolt of pure adrenaline. On the other hand, there’s nothing more frustrating than seeing your team run themselves out of an inning or seeing a baserunner caught directly before a home run.

Finding Corbin

I’ll admit it: I think about Corbin Burnes way more often than is healthy. Not in a Swimfan way, or anything; his blowup 2019 and standout ’20 are just my favorite example of a pitcher adjusting his pitch mix to match his natural talents, and Burnes has no shortage of talent. His fastball sits in the mid-90s with a naturally robust spin rate, and his slider turns batters into pretzels. He also posted a 6.09 FIP in 2019, driven by allowing 17 home runs in only 49 innings.

What was Burnes’ problem? While his fastball has a lot of spin, it’s not the same kind of spin as your average fastball. His fastball is heavy on gyroscopic spin — the football spin that gives sliders and cutters their signature “dot” — and light on transverse (or “active”) spin, which imparts movement. Of the 601 pitchers who threw at least 250 fastballs in 2019, Burnes’ active spin percentage ranked 585th.

That’s not a death knell for pitchers. The bottom of the list is dotted with sinker-ballers (the two types of fastballs are grouped together), and sinkers are unlike four-seamers in two ways. First, they have less transverse spin in general. Second, they don’t need as much transverse spin, because the effect they produce is a pitch that rises less than a batter expects. As they’re still thrown with backspin, less movement means less rise. Read the rest of this entry »


Failure Files: Far From Average

Here’s the honest truth about baseball analysis: Most of the ideas I look into don’t work. That’s mostly hidden under the surface, because it’s not very interesting to read an article about absence of evidence. Hey, did you know that batters who hit very long home runs see no meaningful effect on the rest of their performance that day? I did, because I looked into that at one point, but imagine an article about that and you can kind of see the problem. Read a whole thing looking for a conclusion and find none, and you might be more than a little irritated.

Now that I’ve told you how bad of an idea it is to write about failed ideas, I’d like to introduce you to an article series about ideas that didn’t pan out. I know, I know: I was bemoaning the difficulty of writing such an article just sentences ago. Some failures, however, are more interesting than others, and I’d like to think that I know how to tell the difference. In this intermittent and haphazardly scheduled series, I’ll write about busted ideas that taught me something interesting in their failure, or that simply examine parts of the game that might otherwise escape notice.

In September of this year, I came up with an idea that spent the next month worming its way into my brain. We think of pitch movement as relative to zero, but that’s obviously not true. Sinkers rise more than a spin-less pitch thrown on the same trajectory would; they’re “risers”, in fact. Don’t tell a player that, though, because they’re not comparing these pitches to some meaningless theoretical pitch that no one throws. They’re comparing them to other fastballs, four-seamers to be specific, and if your brain is used to seeing four-seamers, sinkers do indeed sink. Read the rest of this entry »
