Of course, the starting pitcher and, say, Joey Votto would be immune to such a strategy - and perhaps the catcher, too - but any other player could be swapped out for Hamilton and his legs. If the Reds were to replace the first non-Votto, non-pitcher to reach base, I explained, Hamilton would enter most games by the second inning. \"You just lost a whole player for one time on base,\" Hamilton notes.

To further investigate whether the ball - and not PEDs - explains MLB's quick home run increase these past two seasons, I compared the steroid era with a handful of other times in history when the ball's construction is known to have changed. Although the build of the modern ball has been nominally consistent since 1976, MLB has an extensive history of openly altering the ball in earlier epochs. To get a better sense of whether MLB's current offensive spike more closely resembles the steroid era or one of the times the ball changed, I charted home runs per plate appearance around a few of the historical instances of known ball-tinkering, as well as the midpoint of the steroid era. Most historical instances of the ball changing were accompanied by rather dramatic shifts in HR/PA, which helps confirm that the makeup of the baseball can indeed influence power rates. The recent offensive surge, on the other hand, has been both sudden and uniform across the league, resembling previous times in MLB's history when the ball changed.

As Baseball Prospectus writer Matthew Trueblood put it on Monday, \"We can hem and haw about the lack of perfect evidence, and we certainly aren't going to get commissioner Rob Manfred to admit it or anything, but the league juiced the baseball in the summer of 2015, and they haven't unjuiced it.\" In a meeting last July, Manfred told a group of baseball writers that MLB had done \"Extensive testing on the baseballs and found no changes.\" However, he didn't offer any support for that statement, even though there is precedent for MLB sharing the results of its testing, as the league did via press release in June 2000, the highest-home-run-rate year before 2016. To my knowledge, no other member of the media has been offered any evidence that the ball hasn't changed in the past two years, beyond MLB's say-so.", "mimetype": "text/html", "submitted_by": 1, "added_at": "2018-03-19T20:15:12.608Z", "updated_at": "2018-03-19T20:15:26.589Z", "topics": [101], "links": [30, 46, 49, 50, 62, 66, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99, 100]}}, {"model": "documents.document", "pk": 21, "fields": {"state": "ready", "document_type": "a", "title": "We X-Rayed Some MLB Baseballs.

Asked about these findings, MLB noted that it had commissioned a group of scientists and statisticians to investigate any changes to the ball, and that the committee would issue a report on its research soon. According to Alan Nathan, one of the physicists on the commission, the task force found that all the characteristics that MLB regularly measures, including the weight, circumference, seam height and bounciness of the ball, were within ranges that meant variations in the baseballs were unlikely to significantly affect home run rates. To analyze possible changes to the inside of the ball, particularly the core, \"ESPN Sport Science\" purchased one new ball from Rawlings and seven game-used baseballs from eBay, confirming their authenticity through MLB's authenticator program. The eight baseballs we tested were split into two groups: an \"Old group\" of four balls used in games played between August 2014 and May 2015, and a \"New group\" of three balls used in games played between August 2016 and July 2017, plus the brand-new ball. The remainder could be reasonably chalked up to a philosophical shift among MLB hitters, who are likely swinging upward to maximize the number of balls they hit in the air and are not shy about the increase in strikeouts that may come with that approach.

Some of the home run spike might be the result of players gearing their swings to hit more fly balls, but it's clear that diminished air resistance also played a big role. Even before the home run spike began, the ball's air resistance regularly drifted up and down, and the rate of dingers ebbed and flowed with it: In the five-season stretch from 2010-14, well before anyone suspected a juiced ball, monthly MLB-wide drag coefficients were also clearly linked to the home run to fly ball rate. The last three years appear to have featured a series of variations in the ball's bounciness and air resistance that ended up causing the largest, fastest home run increase in history. Nathan found that just a 7 foot difference in batted-ball distance is enough to raise home run rates by 25 percent, which means that MLB's standards are so broad that they could permit a 100 percent change in home run rates without the commissioner ever finding a ball outside the acceptable range.

Rob Arthur mentioned slicker baseballs in his study from this summer as well. As Arthur also points out, this all means that MLB's home run surge can end in an instant: once the baseballs are changed again in a way that reduces the slickness of the balls once more. Will MLB go for that in 2018 to try to get all of these studies to quiet down?

A change in the ball would neatly account for the outcome we've observed: a significant increase in exit velocity and home runs, independent of talent and temperature, without a dramatic change in control of the strike zone. The history of clandestine big league baseball-adjusting goes back more than a century, and there is recent precedent for an unannounced ball change in a high-profile league: Japan's baseball commissioner resigned in 2013 after news broke that NPB had secretly started using a livelier ball. Of course, there could be an innocent explanation for a change in the ball, since even a minor alteration in materials or manufacturing could produce a significant difference in the ball's bounciness, or coefficient of restitution. \"To this point, we have not uncovered anything suggesting that the balls are related to the increased amount of home runs in the second half.\" MLB's analysis also failed to find a conclusive link between weather and last season's increase in scoring. The COR of the 2015 balls was only 0.003 higher, on average, which Nathan dismissed as \"Barely at the accuracy limit of the measurements.\" After studying the results, Nathan concluded: \"My very definite takeaway from the measurements is that there is no compelling evidence that the balls perform differently.\" It's possible that the newer baseballs have lower seams, which would help them fly farther; the NCAA successfully counteracted a power outage of its own by lowering its regulation ball's seam height last season.

While we haven't witnessed notable league-wide changes to fly-ball rate - even as players endeavor to lift the ball - we are perhaps seeing something of a cancellation effect of balls down in the zone, perhaps because of changes to swing plane. If we take for granted that the optimum bat plane for most hitters is a slight uppercut swing - which allows the bat to meet a pitch traveling on a slightly downhill trajectory from the mound - then such a swing should be effective against pitchers lower in the zone.
