Morrison, a highly regarded talent, has struggled with a .234 batting average, 11 home runs and 36 RBIs in 91 games.
"We expect a lot from him, a lot," manager Ozzie Guillen said. "We worked with him. We've talked to him. He don't give me the right answer. He tells me he's OK. I hope he says, 'No, I'm not.'"
Guillen's point is if Morrison is hurt or something is off, that may explain the lack of production.
Still, the Marlins are focusing on getting Morrison to fulfill expectations.
"We're working through it," Guillen said. "The one thing about LoMo is he plays the game right. He's a bulldog. He's going to play through pain. He's going to [run into] walls. He's going to do everything. When you have the type of player like that, you've got to give him the most opportunity that you can to work out of slumps. I hope in the next couple of days he gets better."
Morrison's message to himself and the team is, the season starts today.
On Friday, he took early batting practice, working on staying back on the ball and not lunging.
"Just having better at-bats and barreling balls," Morrison said. "That's how you turn things around. There is no secret to it. Keep working, and it will come."
Before Wednesday's trade, Ramirez was the centerpiece of the franchise. Now is an opportunity for Morrison to make more of an impact, in the clubhouse and on the field.
"I think the reason Ozzie says that I'm a leader on the team is because of the way that I play," Morrison said. "Not the numbers; those come. But the way you play every day. You play through pain, you play through soreness. I think all of that stuff is why he looks at me as a leader."
