Offense is on the rise in Major League Baseball and the home run rate has steadily increased in recent years.

A study by FiveThirtyEight.com found that baseballs used last season were fundamentally different than the baseballs used prior to the 2015 All-Star break. The "cores of recent balls were somewhat less dense," which allows the ball to carry farther.

Justin Verlander retweeted the story with the caption, "Surprising. Oh wait ... been saying this for a couple years now."

Verlander isn't upset that the balls are juiced as long as the playing field is level. He's not happy, however, that Major League Baseball has kept insisting that the balls haven't changed.

"All I'm saying is I don't care if balls are juiced (seriously)," Verlander wrote on Twitter. "We're all using the same ball so it's a fair field. My issue is I don't like being lied to. I knew something was different. Century old records are being broken and numbers are skewed."

Major League Baseball released a memo last year saying the ball has not changed.
