Report: MLB sent memo to teams claiming 'no evidence' balls are juiced

Major League Baseball stands behind its balls.

Despite rampant speculation that something about the makeup of a baseball is inherently different this season, leading to a record number of home runs in 2017, the league reportedly sent a memo to all 30 teams Saturday that insists that the baseballs used in games today are no different than those used in recent years, according to USA TODAY Sports' Bob Nightengale.

"The baseball in use today tests well within the established guidelines on every key performance metric," the memo reads. "Furthermore, there is no evidence that the composition of the ball has changed in any way that would lead to a meaningful impact on on-field play."

It isn't the first time in recent weeks the league has directly intervened in an attempt to dismantle the assumption that altered baseballs are the reason behind more home runs this season.

In June, MLB commissioner Rob Manfred referred to the speculation of juiced baseballs as "conspiracy theories," and admitted the league's self-acclaimed tests supported his stance.

"We have tested the baseball really thoroughly and consistently over a period of time," Manfred said last month. "I know others have tested it and have said certain things.

"Our test results from the labs we believe are the most skilled in this suggest there is nothing about the baseball that can account for the increase in home runs."
