Rob Manfred has once again emphatically denied that Major League Baseball has altered baseballs to generate more offense, amid widespread criticism from some of the game's top pitchers.

"Baseball has done nothing, given no direction for an alteration in the baseball," Manfred said. "The flaw in logic is that baseball wants more home runs. If you sat in owners meetings and listen to people on how the game is played, that is not a sentiment among the owners for whom I work."

Manfred also said "there is no evidence from scientists that the ball is harder" but acknowledged that "the drag of the baseball is less."

MLB has commissioned laser tests to measure seam width and height in an effort to find out why the drag is less, but the league has not been given answers by scientists.
