He played in his 80th game on Sunday, and the 26-year-old says his knee is holding up just fine.
"My knee feels great compared to how it used to," Morrison said. "I still get aches and stuff, but it's night and day. I'm happy with where my knee is and my body health. Now, I just have to work on being more consistent on the field."
It's going to be a busy offseason for Morrison, who is getting married in early November.
Morrison has also remained one of the Marlins' most active players in terms of community work. He is the organization's representative for the prestigious Roberto Clemente Award, which recognizes the community efforts of players.
On the field, missing major parts of 2012 and earlier this season put Morrison in a position of playing catchup. His numbers have been modest, as he's batting .243 with six home runs and 36 RBIs.
Still, he presents a power threat from the left side, an area of weakness for the Marlins.
After the season, Morrison looks forward to being able to do a normal offseason workout.
"It's going to be fun being able to actually strengthen instead of rehab," Morrison said. "I don't have to worry about how my knee feels, because I know it's healthy."
