Release Points: Hey, Psst, Offense Might Be Creeping Up

Dan Rozenson

The real question is why.

Are you ready for the "dead ball era" to be over? There's a chance we're going to see some more offense in the years to come.

Scoring is up across baseball this year. Not only that, but a number of pitcher-friendly trends have plateaued or even reversed themselves. For the first time in recent memory, strikeouts are decreasing in frequency, and home runs—and runs overall—are increasing for only the second time. Take a look below at first-half numbers from the last six seasons.

Release Points: Pitch-Type Benchmarks

Dan Rozenson

What is an average curveball's velocity? How many groundballs does the mean changeup generate? All your questions answered here.

What's an average fastball speed these days? Which pitch types get the most groundballs? It's been several years since Harry Pavlidis last looked at the benchmarks of each pitch type using PITCHf/x. Let's revive the tradition.

Since 2011, the Pitch Info data set has improved in several ways. Harry, Dan Brooks, Lucas Apostoleris, and I, along with readers like you, have vetted our classifications many times over. The data is now corrected for system calibration errors. We've been able to spot more pitchers' split-finger fastballs, moving them out of the changeup group and correctly into the much smaller splitter category. We've also been able to identify pitch sub-types that add to the depth of research we can do, such as by creating a separate “slow curveball" tag for pitchers who throw eephus-like curves in addition to a normal one.

Our intrepid reporter covers the annual Congressional baseball game

At the annual Congressional Baseball Game at Nationals Park yesterday evening, one name kept popping up among the participants: Cedric Richmond. Richmond is the Democratic Representative from Louisiana's 2nd District, covering New Orleans. Republican manager Joe Barton and his Democratic counterpart Mike Doyle both agreed in pregame interviews that Richmond was the best player they'd seen participate in their combined 49 years of involvement with the game. Doyle said, "He's playing on a different level than the rest of us." Richmond led his Democrats to a 7–2 victory, leading the way in all aspects of the game.

Richmond has been the ace pitcher for the Democrats since he was elected in 2010. He's started every game since then and has entertained his colleagues and staffers with the leftover skill he still carries from his college days at Morehouse. His fastball still gets into the low 80s, and he has a curveball and changeup to go with the heat. I didn't get a good look at the change, but I did see the curve plenty. It had an 11-to-5 shape that tended to roll a little bit, but he had impressive command of it. He mixed his pitches well and garnered lots of off-balance swings on the way to a complete-game victory, the seventh in a row for the Democrats.

Release Points: Picking Up the Pace

12

Dan Rozenson

We all know games are shorter this year; the question is which rule changes are making them so.

Early consensus seems to be that the “pace of play” rule changes introduced this year have been both effective at reducing length and minimally invasive to the game itself. After the first week of the season, games were finishing eight minutes quicker than in the same period last year. Since then, there doesn’t seem to have been a lot of interest in the topic. Major League Baseball announced its contentment with the results to such a degree that the fines for batter’s box rule violators were never implemented. As of May 19th, nine-inning games are nine minutes shorter than they were last year. That’s a pretty noticeable difference!

But is the goal supposed to be shorter games in and of themselves, or faster play? Are we getting shorter games the way the rules were designed to achieve that goal? Shorter times might be related to either one of the rule changes imposed this year—no stepping out of the batter’s box, and shorter between-inning breaks—but the implications for future discussion on the issue might be closely tied to which rule(s) are responsible.

Release Points: Where Have You Gone, Stephen Strasburg?

Dan Rozenson

Rewatching every pitch Strasburg has thrown this season to diagnose his problems

Stephen Strasburg’s season has been a frightening experience for me, not just as a Washington Nationals fan but also as a sabermetrician. Dissecting the reasons for his season-long struggles is not easy. To begin with, my brain is struggling with how much of his 6.50 ERA to attribute to bad luck and how much to bad pitching. Matt Trueblood took a good crack at exploring the issue a few weeks ago. Ben Lindbergh and Sam Miller touched upon it earlier this week in their podcast, and left with no good explanations; they concluded it was likely just a random rough patch in his career.

The numbers don’t really point to a strong conclusion. Some of the peripherals say he’ll be fine, and others say he’s in real danger.

To understand Harper's breakthrough, look at what he's done to the breaking balls pitchers threw.

Bryce Harper hit one of the more ridiculous home runs Tuesday night against the Yankees, one of those “oh my goodness I love baseball” ones, on a fast-sinking slider that was about five inches below the strike zone. With what seemed like just a flick of the wrist, Harper had his 10th home run in 12 games. He has as many opposite field homers through 40 games as he did in his first 40 games last year to any field.

Release Points: We've Been Getting Cutters All Wrong

Dan Rozenson

Rethinking a pitch as two pitches (at least).

Tim Hudson throws a cutter. Kenley Jansen throws a cutter. But are we really talking about the same pitch?

It wasn’t that long ago that features popped up across the baseball world heralding the rise of the cutter and the profound effect it was supposedly having on the hitting-pitching balance. Here’s a Sports Illustrated piece from 2011:

Many pitchers are relievers because they never developed a great off-speed pitch. Tyler Clippard now has two.

“The terms splitter and forkball are often used interchangeably to describe a pitch where the index and middle fingers are split around the baseball in any fashion. … Nonetheless, very few pitchers actually throw the slow, tumbling, dropping forkball.” – Mike Fast

The Rangers turned to a backup catcher to pitch in a blowout.

And giving him very good grades.

I had a feeling we might see a position player in Detroit on Thursday, when the Tigers battled the Tribe for 13 innings and got only 10 outs from Robbie Ray. It could easily have been Don Kelly, who pumped 85 mph heat and a curveball in a 2011 game. But instead, in the top of the ninth, Brad Ausmus summoned utility infielder (“the very utility infielderiest of utility infielders,” according to Grant Brisbee) Danny Worth.
