These new balls have a higher BC!!! https://www.washingtonpost.com/news...t-say-how-or-why/?utm_term=.5918a307e789MLB finally admits changes to ball itself fueled home run spike, but doesn’t say how or whyMajor League Baseball on Thursday confirmed for the first time something pitchers in the sport have been saying for more than two years: that changes to the composition and/or behavior of the baseball are responsible, at least in part, for the surge in home runs since the middle of the 2015 season. What remains unexplained, however, is what exactly those changes were, or why they occurred. A committee of 10 scientists and data specialists, formed by Commissioner Rob Manfred, concluded in a report released Thursday that home run surge can be explained, at least partially, by “a change in the aerodynamic properties” of the ball — specifically, “reduced drag for given launch conditions.” The home run surge “is not due to either a livelier, ‘juiced’ ball, or any change in batter or pitcher behavior,” the report concluded. “It seems, instead, to have arisen from a decrease in the ball’s drag properties, which cause it to carry further than previously, given the same set of initial conditions — exit velocity, launch and spray angle, and spin. So there is indirect evidence that the ball has changed, but we don’t yet know how.” “The great mystery is: What in the world has happened that we’ve had a small change in drag — it isn’t large — but one that seems to be systematic enough that it’s affecting offense,” said committee member Lloyd Smith, a professor of mechanical and materials engineering at Washington State University. “We’ve done every test you could imagine, and we just couldn’t nail it down. It’s in there. It’s in the data someplace. But it’s going to take a lot more time and effort [to solve]. “Just to figure out the ‘what’ — is drag there or not? — we had to measure the drag of 22 dozen baseballs. And this was by itself a solid month of two technicians in a lab firing baseballs through the air and seeing how their drag changes.” Though the committee was unable to prove the exact cause of the reduced drag — the “why” — it offered several hypotheses, including that the rubber “pill” at the ball’s core may be more centered in recent years, or that the ball may be staying rounder. According to Baseball-Reference.com, MLB’s home run rate grew in every season from 2014 (0.86 per team-game) to 2017 (1.26), before falling slightly this season (1.13 through Wednesday). The committee’s findings supported Manfred’s contention, made repeatedly the past few years, that nothing material had changed in the manufacturing or the specifications of the baseball. The committee said it found no changes to the size, weight, seam height or coefficient of restitution (or “bounciness”) that would explain the increase. According to Smith, natural variations in the materials used to produce baseballs, including wool yarn and leather covers stitched by hand, give each ball a higher degree of variance in properties than would be found in, say, golf balls. “While it cannot be ruled out that small year-to-year variations in these properties might be a minor contributing factor to the home run surge said,” the report said, “these changes are within normal and expected manufacturing variation.” [In baseball, launch angle just keeps going up, up, up] Analytics websites began noticing the uptick around midseason in 2015, and some pitchers, most prominently Houston Astros ace Justin Verlander, have been outspoken about what they saw as a clear change in the feel, look and/or behavior of the ball. “Major League Baseball wants to put on a show,” Astros left-hander Dallas Keuchel said during last fall’s World Series, which saw a record 25 homers hit in a seven-game series. “Honestly, I think the balls are juiced.” Manfred commissioned the study in August 2017, bringing together physicists, mathematicians, engineers and statisticians, who examined Statcast data, tested and compared the properties of game-used balls from 2012-17, and inspected a Rawlings manufacturing site in Costa Rica where the balls are made. They also considered “changes in player behavior” — including the trend toward hitters swinging with an increased launch angle — as a potential factor, but ruled that out.

There’s a article on cbs sports that some of baseballs top stars are not doing their part of the publicity for baseball to make it a more popular game manfred and mlb probably trying to keep the game more interesting

The study concentrated on the ball after it is hit, reduced drag will change how the ball breaks when pitched, I'm guessing it causes more mistake pitches that get launched also.

Commish Manfred said that in earlier interviews this season. He wasn't keeping any secrets or part of a conspiracy. I saw him interviewed a few times where he stated basically what the study said.

You can basically steal first now on a passed ball third strike, never understood that rule

I’m a basball lifer
MLB is dying on the vine and I’d bet they are trying anything “behind the scenes” the make the game more exciting
They hate rule changes
It’s a different world, attention spans are short.
Homeruns bring excitement
They need to speed it up and I know there are some ideas in the works

Nobody want to see 1-0, boring, pitchers duals. I believe MLB also flattened the seams on the baseball some, which obviously results in less drag, breaking balls don't break as much, etc......advantage to the hitter. They want to see balls flying out of the stadium, and that's also why the owners back in the steroid era knew all about it and didn't give a crap......it put butts in the seats. When they started rebuilding all of these new stadiums they moved the fences in some as well.

They lost me forever with the 1994 strike. "Sorry, I can't survive on 1.2 million a year" didn't sit well with me.

The juiced baseball theory has been around for a few years now, he is just the latest, and highest profile pitcher, to say something.
Some people are suggesting that the stitches are fractionally lower profile than they used to be, which limits the amount of spin pitchers can get on their pitches, and also makes the ball travel farther when hit.
I just turned it on . I was looking bird dogs in the butt this morning.

I do not see a problem with changing the ball. I am sure it has changed many times throughout the years, basketball and football have.

The change in drag may be the reason all these pitchers are throwing 95 to over 100 MPH fastballs. I remember when very few threw 95 MPH. Now almost every pitcher throws over 95 MPH. You don't hear them complaining about it.
