Over the food of a typical significant League Baseball (MLB) game, the two teams will usage well an ext than 50 baseballs. Part balls enter the stands and also become souvenirs for happy fans, of course, but there space times when the balls simply acquire so scuffed during game play come warrant a replacement. The baseballs have to be in great condition to be usable — us don’t want a low top quality ball interfering with the game’s outcome.

You are watching: What do they do with used baseballs

So you’d mean that MLB games use brand new, fresh-from-the-box ones. They do, however there’s a difficulty with new balls; it transforms out the baseballs aren’t sold in ready-to-use condition — not, in ~ least, if you a significant League caliber pitcher. Factory-sealed baseballs space a small too perfect. Lock coated in a shining gloss which provides them look good on a store shelf, but, unfortunately, makes them a tiny hard come grip, specifically if you trying to throw an 80 mile an hour curve ball through one invisible target the size of a mini-fridge. The baseballs need additional processing and also care: they need to acquire a small dirty.

As in: someone demands to literally obstacle the balls through dirt.

And no just any type of dirt will do. It needs to be special. Luckily, MLB has actually a link — there’s a firm which, every year, provides special mud to the league. Before every game, one of the umpires (or someone from the stadium staff) bring away these five dozen or therefore balls and also rubs each and also every one of them with a Lena Blackburne Baseball Rubbing Mud, named for a coach who, apparently, found this special mud in the 1930s.

Where walk Blackburne find it? that’s a an enig the firm won’t share.

Well, the specifics space a secret, at least. We recognize that the firm sources its dirt from the Delaware river basin, as the Christian scientific research Monitor reported, and also likely native a tributary close to Delran, brand-new Jersey, per another source. Jim Bintliff, the owner the the firm (and a descendant of Blackburne), won’t reveal his an enig source. The does, however, have no troubles explaining what renders the mud special — the is very fine, with the consistency of cacao pudding, which — he insurance claims — makes it able to remove the sheen there is no damaging the leather, other no various other mud can do quite as well.

That may be an ext tradition than science — MLB has been using Lena Blackburne Baseball Rubbing Mud because the 1950s or so, and also it’s likely that the composition of the dirt has adjusted over time, and similarly likely the the process of do a baseball has changed as well. That being the case, some might question why MLB insists on offering Lena Blackburne a syndicate on the round treatment dirt. Yet don’t think this is some sort of large moneymaker. Blackburne selling a 32-ounce container that the mud for about $50, and also that’s sufficient to last an MLB team whole season. Consisting of all the minor league and college groups which to buy the one-of-a-kind mud, the firm only sells about $25,000 precious of dirt each year.

Bonus Fact
: The dirt isn’t the only thing special around the de-sheeining that a baseball. The balls additionally have to it is in “properly rubbed” — a phrase right out of MLB’s official rule book (pdf here; it’s on page 24). Dominance 3.01 starts by noting that “before the game the umpire shall” execute a number of things, and subpart (c) referrals the mud-rubbing. And apparently, that’s a pretty huge deal. The Christian scientific research Monitor describes in the story linked-to above: “There’s a special technique to rubbing up a baseball. The dirt – and a tiny water – goes on the leather, but not the seams. If it’s not done right, the pitcher will certainly throw the ball ago to the umpire. ‘If you don’t apply the mud uniformly,” warns , “the pitcher can’t gain the ideal grip. In ~ 90-plus miles every hour, the doesn’t take lot to litter the tracking off.”

Double bonus!: Every single one that the baseball provides by MLB originates from the same manufacturing facility in Costa Rica — and every single baseball is hand-stitched. There have been some initiatives to automate the manufacturing process entirely, however for factors unclear, an innovation can’t properly duplicate the stitching procedure — it takes a person touch. The Costa Rican manufacturing facility employs 300 world who, collectively, develop 2.4 million such baseballs a year.
