Boston Red Sox pitching prospect Michael Kopech is making news again — and not in a good way.

Kopech, Boston’s first-round pick in the 2014 draft, fractured his right hand during a recent altercation with a teammate, according to He was seen wearing a cast on his throwing hand at Red Sox camp in Fort Myers, Fla., on Tuesday.

Red Sox general manager Mike Hazen expressed his disappointment in Kopech while speaking with reporters Tuesday afternoon.

"It was stupid," Hazen said. "He’s going to have to grow up, obviously, with the things that have happened so far. He’s got a long road to go to get to the big leagues. He obviously has a ton of potential. He’s got a long way to go. These types of things, you don’t want to put more barriers in front of you than playing professional baseball already presents you."

Hazen said he does not yet know the extent of the injury or if Kopech will face any discipline for his role in the fight.

"He’s very apologetic, he’s very disappointed by what happened and now he’s going to have to pay for it with regard to more lost time."

It’s not the first time Kopech has been in hot water with Red Sox management. Last season, the 19-year-old right-hander tested positive for a banned substance, the stimulant Oxilofrine, and was suspended for 50 games.

Kopech, who is considered one of the top prospects in the organization, went 4-6 with a 2.63 ERA in 15 starts for Single-A Greenville last season.
