Baseballs Are More Consistently Juiced Than Ever | FiveThirtyEight

Making the balls more consistent might further affect MLB’s overall home run rate, but it also means pitchers and hitters should end up with a more even playing field. Such consistency won’t help every player, but at least they’ll have a better idea of what they’re working with — a ball that travels farther and flies faster than it used to.

Juiced baseballs? Rob Manfred says he’s ‘certain’ balls are within specified limits - CBSSports.com

A Jonah Keri two-fer.

How much more would it cost narrow the specifications allowed?
According to Wikipedia:

A baseball is a ball used in the sport of the same name, baseball. The ball features a rubber or cork center, wrapped in yarn, and covered, in the words of the Official Baseball Rules “with two strips of white horsehide or cowhide, tightly stitched together.” It is 9.00–9.25 inches (228.60–234.95 mm) in circumference, (2.86–2.94 in or 72.64–74.68 mm in diameter), and masses from 5.00 to 5.25 ounces (141.75 to 148.83 g).[1] The yarn or string used to wrap the baseball can be up to one mile (1.6 km) in length. Some are wrapped in a plastic-like covering.

COR Specifications

For a ball to make it to the big leagues, its COR must land between 0.514 and 0.578. Juiced balls would have a COR exceeding that maximum value.
Amid the elevated home run rate, MLB recently shared COR values and other metrics for league baseballs measured by the independent Baseball Research Center at the University of Massachusetts, Lowell, over the past several years.
