How to Think of Postseason Contention, Elimination

We’re at that time of the regular season during which most teams are making a final push to clinch a spot in the postseason. Some teams (such as the Cubs) have basically already clinched a spot and some others (such as the Twins) are already mathematically eliminated. Most teams fall somewhere in between.

Many baseball fans will look at the standings every day in September. If they see their favorite team is leading its respective division, they’ll hope that, for the rest of the regular season, that team win will more games than anyone else in the division, thus allowing that team to become the division champion. This is guaranteed.

If they see, on the other hand, that their favorite team is not leading its respective division, they will check the number of games remaining and the number of games by which their team is behind the division leader. If the number of games remaining is greater than the number of games behind, then they can hold out hope that their team can win the division by winning all its remaining games, while the division leader loses all their remaining games. Unfortunately, this is not always guaranteed.

The type of error is made not only by Average Joe sports fans, but also professional sportswriters.  This article will describe these tricky scenarios in which teams are eliminated from postseason contention.

Dave Dombrowski Has Been Good at Trading Prospects

Know this — Dave Dombrowski likes to make trades. He was first named a general manager back on July 5, 1988, assuming the title of “youngest GM in the game” back before it was cool with the Montreal Expos. He made his first trade on July 13. His aggressive nature was sometimes just off center stage, as the teams he had previously helmed — the Expos, Marlins and Tigers — have rarely been media darlings. But now he is running the Red Sox, and they get plenty of coverage. While that level of coverage might not be fair or warranted, his deals are being scrutinized hard these days. Is he gutting the farm system? Or does Dombrowski know how to pick ’em? I thought I’d take an objective stab at his trade record.

Tommy John Surgeries: 2016 Update

It’s no secret that, over the last few years, the number of Tommy John surgeries has increased across all levels of baseball. As we emerge from the All-Star break, let’s take a snapshot of the current state of Tommy John surgeries at the professional ranks.

New Tommy John Surgeries
Let’s start with some good news. The number of Tommy John surgeries at the major-league level is down in 2016 compared with the last couple of seasons. Comparing totals at this point in the season over recent years, there have been fewer Tommy John surgeries to date this year than any since 2011.

In the past five seasons, I’ve attempted to track Tommy John surgeries at the minor-league level more closely than in prior years. This information is much more difficult to collect, and certainly there will be many surgeries missing from the list every season. Looking only at surgeries known to have been performed by this time in the year, however, the 2016 campaign looks more like 2012-2013 than the last two years where surgery counts had spiked.

So the most interesting question here is: has something actually changed to cause the number of Tommy John surgeries to drop this year compared with the last two seasons?

I can’t say that I know the answer, but I suspect it’s due to a number of factors.

Are Veterans Better at Slump-Busting?

Way back at the winter meetings, Brad Ausmus said a thing that I found interesting. It’s stuck with me ever since, gathering moss as I’ve pondered it occasionally. But by itself, it raised my eyebrow and set me on a path.

“Especially hitting,” began Ausmus. And continued:

[W]henever you recover from a struggle or go through a slump, you fall back on that experience anytime it happens again. That’s absolutely true. I can tell you that from experience. That’s why veteran players are much better equipped to handle slumps than young players just because of the experiences.

There’s a lot to unpack here, but before we ask the players and the numbers, I thought it would be interesting to call back to a psychology experiment with which I once assisted in college. In a study colloquially called The Beeper Study run by Laura Carstensen at Stanford University, we found that getting older led to more emotional stability and happiness.

Introducing the Batter-Specific Run-Expectancy Tool

Today at FanGraphs, we’re introducing an interactive run-expectancy tool that incorporates the batter’s skill into the run-expectancy value. The tool, developed by the rather incredible Sean Dolinar, allows the user to input a few factors, including one to account for the batter, and in turn spits out a number estimating how many runs will be scored for the rest of the inning.

The Slider Moves Differently to Different Locations

I gave Royals’ right-hander Chris Young a bit of an incredulous look — “You’re throwing the slider a ton this year!” He shrugged. Sure. “It’s okay, you can throw it inside and out, and it’s been good. But it moves a little differently depending on where you throw it.”

Young then mimicked the release point when trying to throw a slider inside to a right-handed hitter, and then he showed where the release point might be when throwing it outside to a right-handed hitter. One was straight to the plate, and the other had more side-to-side finish to it.

If you’ve pitched competitively — or, at least, possess more experience than my own, which is limited to throwing a whiffle ball to my kid while he imitates Julio Franco — this may be old hat to you. But to me, it was surprising and also totally logical at the same time. I immediately wanted to know what this looked like.

What Pitchers (and Numbers) Say About Pitching in the Cold

Maybe it was the fact that she spent her formative years in Germany, while I spent most of mine in Jamaica and America’s South, but my mother and I have always disagreed about a fundamental thing when it comes to the weather. For her, she wants the sun. It doesn’t matter if it’s bitter cold and dry; if the sun’s out, she’s fine. I’d rather it was warm. Don’t care if there’s a drizzle or humidity or whatever.

It turns out, when we were disagreeing about these things, we were really talking about pitching. Mostly because life is pitching and pitching is life.

But also because the temperature, and the temperature alone, does not tell the story of pitching in the cold. It’ll make sense, just stick with it.

Baseball’s New Approach to the Changeup

Baseball can be slow to change. We’ve had this idea for decades that certain pitch types have platoon splits, and that you should avoid them in certain situations because of it. Righties, don’t throw sliders to lefties! It’s Baseball 101.

Think of the changeup, too. “Does he have a changeup?” or some variation on the theme is the first question uttered of any prospect on the way up. It’s shorthand for “can he be a starter?” because we think of changeups as weapons against the opposite hand. A righty will need one to get lefties out and turn the lineup over, back to the other righties, who will be dispatched using breaking balls.

As with all conventional wisdom, this notion of handedness and pitch types should be rife for manipulation. Say you could use your changeup effectively against same-handed hitters, for example. You could have a fastball/changeup starter that was equally effective against both hands, despite the history of platoon splits on the pitch.

To the innovators go the spoils. And we’re starting to see some innovators.

Has the League Lost Its Two Strike Approach?

Ask a current major league batter about his two strike approach. Watch the words stop coming out of their mouth.

About twenty minutes into a long conversation with Josh Donaldson about his approach to swinging the bat, we got to what he can do to deal with the low and away pitch in counts where he has to protect. I didn’t realize it, but I’d asked for his two-strike approach. “I don’t really want to get too in depth into that,” he said, shutting off the inquiry.

Brandon Moss, the most loquacious of interviews, just laughed when I asked him about how his approach changed. Quickly, I learned not to talk about it.

But it was still out there. And when Paul Konerko told me (during another long conversation about hitting) that he felt like a strikeout was a weakness, my ears perked up. He’d tell me about his two-strike approach. He wasn’t in the league any more.

Maybe Ground-Ball Pitchers Actually Are a Bad Bet?

Maybe you remember, but a couple of years ago, Bill James went on a rant about ground-ball pitchers. It started with a bang:

Make a list of the best pitchers in baseball. Make a list of the best pitchers in baseball, in any era, and what you will find is that 80% of them are not ground ball pitchers. They’re fly ball pitchers.

And it got louder. James felt that they got injured often, and flamed out. “They’re great for two years, and then they blow up,” he wrote. “Always.”

The response was swift.
