There are so many variables in play that are impossible to quantify. How the ball is transported from the Rawlings factory in Costa Rica to each MLB city, how long the ball is stored in the humidor, and all sorts of other stuff matters quite a bit. Every time a baseball warms up and cools down, its physical properties change. Everything in the ball (the leather, the cork, etc.) experiences wear and tear, for lack of a better term. Giancarlo Stanton has the best career ratio among active players with 13.98 at bats per home run. A barrel is essentially the best possible contact in terms of exit velocity and launch angle.
All of this prompted MLB commissioner Rob Manfred in August 2017 to bring together various experts in the fields of physics and quantitative analysis to try to find out what was going on. The committee focused its efforts on studying the physical properties of the baseball, weather and climate conditions, and player behavior. In broad terms, the committee found that baseballs were experiencing less drag in the air, which allowed them to travel farther, but they couldn't pin down a reason for the change.
Who has the home run record before Mark McGwire?
Changes to the baseball itself are the most straightforward explanation, though it should be noted they're not the only possible explanation. She hypothesized that Rawlings, starting with the 2019 batch, began machine drying the baseballs whereas before they allowed baseballs to air dry. That, in turn, perhaps allowed Rawlings to better meet MLB's increased demand for baseballs (Triple-A used MLB baseballs in 2019, and, just as in MLB, home run rates vaulted). The physical changes she found in the baseballs starting in 2019 are consistent with what would happen if you applied heat to a baseball to speed up the drying process. Dr. Willis' findings didn't exactly align with those of the MLB-assembled panel while at the same time reinforcing the fact that the ball changed prior to the 2019 season.
Aaron Judge also had a historic season, setting a home run record for rookies. But his 208 strikeouts were the most in baseball, and his 2.6 AB/ K shows that he struck out more frequently than every third at-bat. In comparison, Mike Moustakas hit 38 home runs , but he struck out less than half as frequently as Judge, with an AB/K figure of 5.9. This gave Moustakas a HRKAB of 8.7, which is not too far above the 7.8 that Judge had. This is another illustration of why using HRKAB can yield greater insight than home run totals by themselves.

The season is still young and we need a lot more data before we have a full understanding of how this baseball works and the humidor's impact. The early returns suggest a return to 2013 and 2014, the last time teams averaged fewer than a home run per game, and offense was this low league-wide. In baseball statistics, at bats per home run (AB/HR) is a way to measure how frequently a batter hits a home run. It is determined by dividing the number of at bats by the number of home runs hit.
Mark McGwire possesses the MLB record for this statistic with a career ratio of 10.61 at bats per home run and Babe Ruth is second, with 11.76 at bats per home run. Aaron Judge has the best career ratio among active players with 11.99 at bats per home run, as of October 5, 2022. The purpose of this article is to explore power hitter effectiveness. HRKAB allows us to compare hitters on an apples-to-apples basis. For example, in 2017, Giancarlo Stanton hit 59 home runs and had an HRKAB of 6.46. This number is worse than the 1.40 HRKAB of Barry Bonds in 2001, the year he hit 73 home runs.

He passed Hank Aaron to take the top spot on the all-time list on August 7, 2007. Customized picks for college football bowl pick’em contests . Now let's undertake a brief chronicling of how the ball has changed over the last half-decade-plus or so, which will set the scene for a deep dive into the 2022 season thus far. Barry Bonds holds the Major League Baseball home run record with 762. Mark McGwire holds the career record for fewest at bats per home run with at least 3000 plate appearances, at 10.61.
As great as all of these seasons are, in terms of the total number of home runs, they are not the best seasons in Table 3 in terms of HRKAB. The best season in the table by this measure is the 0.22 that Albert Pujols had in 2006. Pujols needed more than 10 at-bats to hit a home run that season, but his HRKAB number was very low because of the low frequency with which he struck out.

He runs marathons when not watching or writing about baseball. It's not quite that simple, of course, but clearly the humidor is having some affect on home runs. The weather will warm up in the coming weeks and soon it will be stick-to-your-seat humid in many MLB cities. The ball will behave differently because the climate will be different, so the humidor will change the properties of the baseball even more. The home run rate in the 10 parks that used the humidor in 2021 is down 0.7 percentage points.
It's down 1.6 percentage points in the other 20 parks, the parks that did not have humidor in 2021 but do have one in 2022. If we say the 0.7 percentage point decline is a result of the ball being changed, then the other 0.9 percentage points are the result of the humidor. The pitcher who holds the record for the most no-hitters, with seven in his career, is Nolan Ryan. 500 — is perhaps the most dominant stretch by any player.
The 2017 season was his second year with the Oakland A’s, and he only started playing regularly in June. He had only 189 at-bats in 59 games, but his ratio of AB/HR was 7.88 (better than Stanton at 10.1) and his HRKAB was 4.73 (better than Stanton at 6.5). The sample size is too small to draw meaningful conclusions, but Olson even being on the list shows the advantage of using HRKAB as a measure instead of just the absolute number of home runs.
The 2017 home run leader, Giancarlo Stanton, is used to demonstrate the calculations. Stanton had a historic 2017 campaign, hitting 59 home runs. He accomplished this feat in 597 at-bats while also striking out 163 times. Therefore, his AB/HR and AB/K numbers are 10.12 and 3.66 respectively.
However, Bradford William Davis of Business Insider reported in November of last year that Dr. Willis discovered the use of two different types of baseballs in 2021. One was the lighter ball designed to carry less and the other was a batch of heavier, livelier balls. MLB blamed supply-chain disruption caused by the pandemic for the mixing of batches. Whatever the reasons, it was a frustrating dynamic for pitchers and batters alike. In this case, however, smaller numbers indicate poorer performance, because it means that there were fewer at-bats between each strikeout.
Data for the 2017 season for all batters with more than 400 at-bats are used to test this hypothesis. Suffice it to say, MLB's recent history is rife with inconsistency when it comes to the properties of the actual, physical baseball itself. This has resulted in a great deal of unpredictability from year to year, especially when it comes to home run rates. In Major League Baseball , the 50 home run club is the group of batters who have hit 50 or more home runs in a single season. Since 1927, the baseball home run King was Babe Ruth, who had hit .
Babe Ruth, Mark McGwire and Sammy Sosa have accomplished the feat the most times . Sosa and McGwire accomplished their four seasons consecutively. First, smaller numbers are better in Figure 2, since a smaller number means that it took fewer at-bats to produce a home run. Between 1903 and 1918, hitters had between 160 and 329 at-bats per home run. The figure stood at 286 in 1918 but declined precipitously over the next three years,as offense increased dramatically, to 91 in 1921.
AB/HR continued to decline at a slower rate until 1962, when it bottomed at 37. As pitching gained prominence during the 1960s, AB/HR increased to 59 in 1976. Since that year, AB/HR have declined by about half to 27 in 2017.
