If the Ball Isn’t Juiced, Then What Explains the Homer Surge?

Ringer staff writer and FanGraphs podcaster Ben Lindbergh exhibited some excellent reporting earlier this week, obtaining MLB’s study on the properties of its baseballs. It was a valiant attempt to learn whether the ball itself is responsible for the game’s curious home-run surge. Last year, Lindbergh and Rob Arthur went as far as dissecting some balls to study, wondering if juiced balls were the “new steroids.”

This year, the home-run rate on fly balls is 12.8%. Last year, it was the same. Both marks are the highest on record and certainly grab our attention.

Lindbergh has been on the case of the juiced ball for a while. In light of that fact, it’s somewhat unsatisfying that the report he obtained doesn’t support the juiced-ball theory. While this conclusion naturally depends upon the assumption that MLB’s study was conducted in good faith, Dr. Alan Nathan — friend of FanGraphs and professor emeritus of physics at the University of Illinois — was asked by MLB to review the research as an independent source. Lindbergh spoked with Nathan.

“Quite frankly, I was disappointed at that result, because I was hoping I’d find something,” Nathan, who was compensated by MLB for the time he spent studying the BRC report, tells me by phone. However, he says, “I saw nothing in the data that was presented that suggests that the ball has been altered at all.”

Wrote Lindbergh in conclusion:

If the spread of dingers has less to do with COR or seam height than with a wave of Yonder Alonso–like breakouts by hitters who’ve tailored their swings to lift low pitches, then pitchers could exploit those uppercuts by raising their own sights … The historic performance we’ve seen since mid-2015 still supports at least a little skepticism about the true roots of baseball’s home run revolution; without witnessing the tests, we can’t consider these findings definitive. But the “juiced ball” hypothesis does seem much less likely than I thought it did two days ago. “It has every look of being suspicious,” Nathan says about the timing of baseball’s big-fly bailout. “But as I said, there’s nothing I could find that suggests anything amiss.”

Everyone interested in the home-run surge has a theory about its causes.

Jeff Sullivan FanGraphs Chat — 5/12/17

9:04
Jeff Sullivan: Hello friends

9:04
Jeff Sullivan: Welcome to Friday baseball chat

9:04
Bork: Hello, friend!

Jeff Sullivan: Hello friend

9:05
Be a Dahl: David Dahl seems like a key long term piece for the Rockies. Do you think they turn him into a part time player or send him to the minors until Mark Reynolds cools down?

9:06
Jeff Sullivan: Neither would be very surprising and neither would really be that bad of a situation for Dahl to find himself in. I don’t think the Rockies are at risk of stunting his development if they don’t play him every single day in the major leagues. Besides, he still has to get healthy first, and Mark Reynolds presumably can’t keep this going forever

The Fringe Five: Baseball’s Most Compelling Fringe Prospects

Fringe Five Scoreboards: 2016 | 2015 | 2014 | 2013.

The Fringe Five is a weekly regular-season exercise, introduced a few years ago by the present author, wherein that same author utilizes regressed stats, scouting reports, and also his own fallible intuition to identify and/or continue monitoring the most compelling fringe prospects in all of baseball.

Central to the exercise, of course, is a definition of the word fringe, a term which possesses different connotations for different sorts of readers. For the purposes of the column this year, a fringe prospect (and therefore one eligible for inclusion among the Five) is any rookie-eligible player at High-A or above who (a) was omitted from the preseason prospect lists produced by Baseball America, Baseball Prospectus, MLB.com, John Sickels*, and (most importantly) lead prospect analyst Eric Longenhagen and also who (b) is currently absent from a major-league roster. Players appearing on a midseason list will also be excluded from eligibility.

*All 200 names!

In the final analysis, the basic idea is this: to recognize those prospects who are perhaps receiving less notoriety than their talents or performance might otherwise warrant.

*****

Beau Burrows, RHP, Detroit (Profile)
Burrows is unusual among the players typically included here. He’s a former first-round selection, for one. And for two, he’s considered one of the top prospects in his organization. These aren’t the sort of qualities shared by residents of this column like Sherman Johnson or Max Schrock. Indeed, including a player here who possesses those qualities would appear to contradict the very mission of this weekly effort.

And yet, Burrows has appeared within zero of the relevant top-100 lists as a professional — was, in fact, omitted from John Sickels’ list of 200 prospects published before the season. A bit of context reveals why that might be. As Eric Longenhagen noted in December, Burrows was “seen as a bit of an overdraft” when he was selected out of a Texas high school in 2015. Moreover, the organization to which he belongs, the Detroit Tigers, has routinely featured fewer high-end prospects than almost every other system. Nor does this year represent an exception to that rule: Detroit placed 25th in Baseball America’s preseason organizational talent rankings, the club’s best ranking since 2012. Being regarded as one of the Tigers’ best prospects, in other words, isn’t equivalent to a similar honor for those minor leaguers employed by Atlanta or the Yankees.

Whatever the reasons for his omission, he’s pitched well this season. After appearing among the Next Five last week, Burrows recorded a 7:0 strikeout-to-walk ratio against 24 batters over 7.0 innings in a start versus St. Louis’s High-A Florida State League affiliate (box).

Here’s video from last year of the three main pitches in his repertoire, a fastball (usually in the mid-90s), a curve, and then probably a changeup:

Do the Reds Have Baseball’s Best Defense?

This started as a post about Eugenio Suarez. Suarez has gotten off to a big offensive start, and that’s drawn a certain amount of attention, yet more behind the scenes, he’s also taken a step forward in the field. The other day a baseball person said he’s gotten about as good at third base as Nolan Arenado. I don’t know if that’s actually true, but even just the idea was enough to push me to Suarez’s player page. And, sure enough, by the numbers we have — DRS and UZR — Suarez is playing like a better third baseman.

I checked to see where Suarez might rank among the most-improved defenders, league-wide. I know it’s early, but I still wanted to see. Suarez ranks super high. Yet near the top of the list, there’s also Jose Peraza. And there’s also Joey Votto. You don’t have to scroll far to find Scott Schebler. Forget about Suarez. I mean, forget about Suarez, individually. What Suarez is doing is interesting, and he’ll get his own post one of these days, but I’m more intrigued by the Reds as a whole defensive unit. It’s played like the league’s best defensive unit.

Here’s How the Rockies Are Winning the West

The Rockies were this offseason’s popular dark horse. Not everybody agreed on that, naturally, but if they did, then the Rockies wouldn’t have been a very good dark-horse candidate. A team has to be rated low in order to be underrated, and there was plenty of chatter the Rockies could surprise and push for the wild card. The FanGraphs community determined the preseason projections were too low on the club, so coming in, there was a certain amount of hype. There was faith! Faith in the Colorado Rockies.

Among the things that have happened: Ian Desmond got hurt. Tom Murphy got hurt. Tony Wolters got hurt. Jon Gray got hurt. David Dahl got hurt. And Chad Bettis got sick. Over the course of the last few months, the Rockies roster has been beaten and battered. And it’s also managed to win 22 of 35 games. At this writing, it’s the Rockies who are on top of the NL West, and it’s the Rockies who have so substantially boosted their own chances of making the playoffs. For the first time in so many years, the Rockies could be delivering on their promise. There are two major reasons why they are where they are.

What Is Up With the Cubs Rotation?

After getting swept by the New York Yankees and losing two out of three to the Colorado Rockies, the Chicago Cubs are now sitting on a .500 record. By run differential or BaseRuns expected performance, tools that strip out sequencing, the answer is the same; the Cubs have played pretty much like a .500 team. The offense has been a little worse than average, the pitching a little better than average, but overall, the team has played roughly like an 81 win team so far.

Of course, this isn’t what recent Cubs teams have played like.

In 2015 and 2016, Cubs starters topped all of Major League Baseball with 36.3 WAR, just ahead of the Nationals, Mets, and Dodgers. The starters’ 3.50 FIP, without even considering the impact of defense or the potential of inducing weak contact, has been the best in the majors. The Cubs have returned almost all of last year’s staff intact, with Jon Lester, Jake Arrieta, Kyle Hendricks present for each of the past two seasons and John Lackey around last year.

The question we are trying to answer here is what is responsible for the downturn in results. We are just 34 games into the season, so we could chalk it up to luck. We could try to determine if the talent level has changed in any way, which might cause us to lower our expectations, and we could point to some outside factors that aren’t luck, but aren’t necessarily the responsibility of the pitchers, like defense. To frame our understanding of what is going on, it probably helps to create some expectations of what we would expect to see from a Cubs rotation this season. While Brett Anderson has made six starts, he’s only pitched 12% of the Cubs starter innings, and little was expected of him, so we will focus on the four returnees. Read the rest of this entry »

Daily Prospect Notes 5/11

Daily notes on prospects from lead prospect analyst Eric Longenhagen. Read previous installments here.

JoJo Romero, LHP, Philadelphia (Profile)
Level: Low-A   Age: 20   Org Rank: 29   Top 100: NR
Line: 8 IP, 3 BB, 1 H, 8 K

Notes
Drafted out of Yavapai JC (the same school from which Philadelphia drafted Ken Giles) in last year’s fourth round, Romero was a short but athletic lefty with a fringey but late-wiggling fastball and potential plus changeup. He has had command issues and was homer-prone at Yavapai (whose home field is laughably small) which, due to a lack of fastball plane, some scouts thought might carry into pro ball. But Romero’s once below average breaking ball has improved and he’s locating it down and to his glove side with consistency, back-footing it against righties and garnering swings and misses down and away from lefties. He still has a back end starter’s ceiling but now that Romero has added another weapon with which to attack right-handed hitters, it’s a bit easier to see. Below is a clipping of the swings and misses Romero induced from a loaded Charleston lineup, which featured six prospects from our Yankees list, last week.
