A team of scientists are expected to release their findings into whether MLB balls are being juiced.
Major League Baseball commissioned the study prompted by an increasing number of home runs.
This year the league is on pace to mark 6,700 homers, 1,100 more than last year.
There has been speculation the balls have been altered to reduce drag, making them fly further.
An earlier investigation found balls aren't intentionally juiced, but gave no explanation why they seem to be soaring a longer distance.
