Jason Heyward struggled at the plate, hitting just .230, in his first season with the Chicago Cubs.

Heyward helped the Cubs win the World Series and also took home his fourth Gold Glove award in 2016.

Theo Epstein and Jed Hoyer relayed that Heyward is working more than usual this offseason in hopes of increasing his production at the plate.

"You're not re-inventing him but getting him back to some of the places where he had the most success," Hoyer said. "That's what [Cubs fans] know of him, the one year [in 2016], but if you look back at his career, he's has some really good offensive seasons.

"We want to tweak his mechanics to the times when he had success -- 27 homers in 2012 -- and get him back to those places," Hoyer added. "We're not asking him to do new things but go back to doing things he did well. He's totally bought in and excited to get started."

Epstein said Heyward made an impact with his defensive skills and baserunning and there's more to come.

"Cubs fans haven't seen the type of hitter that Jason Heyward is -- and can be -- yet," Epstein said. "But I think they will."
