The balls aren’t juiced: MLB explains rise in home runs

Manfred cited last year’s report, written by a committee of scientists and data specialists, which identified the pill at the center of the ball playing a factor. If the pill is not perfectly centered, the ball wobbles when hit and creates more drag.

“We think one of the things that may be happening is they’re getting better at centering the pill, [which] creates less drag,” Manfred said. “In addition to that, there’s all these man-made issues: hand-stitched, where it’s stored after it’s made, where it’s stored at the ballpark, who puts the mud on the ball, how much mud they put on the ball. It’s really difficult to isolate any single cause. But we do think it’s a drag issue.”

I thought it had been established that the seams were different, creating less drag.

Did I imagine that?

...so what you're saying is that the ball is juiced?

“We think one of the things that may be happening is they’re getting better at centering the pill, [which] creates less drag,” Manfred said. “In addition to that, there’s all these man-made issues: hand-stitched, where it’s stored after it’s made, where it’s stored at the ballpark, who puts the mud on the ball, how much mud they put on the ball.

I'll have to think about this a bit, but my first reaction is that the pill being off-center does not create more drag, it simply sends the ball on a very slightly longer course as it wobbles. Much like if you were in a huge rush and you had a choice of taking a street that went in a straight line or Mulholland Drive with zero traffic (drag) on either, you'd choose the straight street because you'd cover less distance in the time allotted.

So it takes ever so slightly more time to go that-a-way because the pill adds to the amount of time that it's going anywhere *but* that-a-way. Our two test balls are still traveling through the same air at the same temperature and pressure/density. A nit-picky point, but it's not drag in the sense that the seams stick up less and therefore allow the ball to travel quicker than older balls in the same straight-line distance.

They're no longer unjuiced.

They're very juicy balls.

AAA is using MLB balls this year.

C'mon. It's all semantics at this point. Freddie Freeman is on pace for 45 homers. The ball is juiced.

Yeah, but Freeman is, you know, like really good with the wood and there was always a slight possibility of something like this happening.

Christian Vazquez, Red Sox catcher, after hitting 9 homers in 4 years of part time play, has 9 homers in 62 games already this year. Not saying that's conclusive of a juiced ball, but c'mon, there's something going on there. Christian is plenty good behind the dish but at the dish, not so much....

Tommy LaStella is happy to hear that the balls aren't juiced.

And yet...MLB celebrates home runs with...

A HOME RUN DERBY!!

There's even a thread about it right here on this very web site.
   14. Walt Davis Posted: June 23, 2019 at 03:12 AM (#5855137)
C'mon, LaStella has always had a little Ichiro in him and it just turns out that Tommy wanted to this year.

The Cubs are about 90 ahead of last year's pace, 30 ahead of 2017's pace, 50 ahead of 2016's pace. The Cubs don't even have a player in the NL top 10.

the phillies have hit 91 HRs and given up 126 HRs.

can someone tell them they're doing it wrong?

This is a very semantic-y thing to say. A longer path means more (total) drag, or more drag per linear inch, or ...

Which is why I continued:

A nit-picky point, but it's not drag in the sense that the seams stick up less and therefore allow the ball to travel quicker than older balls in the same straight-line distance.

"drag per linear inch" has 2 components and I'm saying the drag component is held constant while the linear inches are what change; this tells me that the drag coefficient is not what is causing this BludgeonBall phenomenon.

The seams of the ball and the coefficient of resistance of the leather as finished when the pitcher receives it create a fixed amount of drag while traveling through the air. This air resistance does not vary depending on the path that the ball takes.

Put another way, your tires have a certain amount of rolling resistance (drag) that does not change when you take a longer route home (just ask Supertramp). The reason it takes longer to get home is not increased rolling resistance, it's that you took a longer path which takes more time. That's not the result of increased drag, that's the result of taking a longer route. Same with a ball in flight "wiggling" instead of taking a true straight flight path.

time = (distance / velocity)

I don't expect Manfred to know or care about this difference, but as pointed out above he basically admitted that the balls are indeed juiced while trying to explain how they are not. The proof is in the pudding this season.

why would a ball wobble more when its off center than when its centered?

Is the assumption that a centered cushion will not wobble? If so then a off center cushion at some pt will be at the center and stop wobbling... OR another way: if an off center ball wobbles, why not a centered ball what is stopping that?

THere was a study that I saw about the mid season change in 2015 (I think) that concluded the ball was livlier. I tried to post it but for some reason it didnt get posted. I dont think it ever was posted.

It's off balance. The center of mass is not co-located with the geometrical center. Think of an off balance ceiling fan.

Or an unbalanced load in a washing machine.

The Twins, Mariners, and Brewers are all on a pace to break the team season home run record the Yankees set last year. (And the Yanks are on a pace to miss tying last year's mark by 0.56 HR.) MLB is on a pace to hit 493 more HRs than the record 2017 season, and 1013 more than last year.

Maybe it's Global Warming???
