"I'm feeling better," Koskie said. "But I still can't move beyond it."
Koskie made the visit to the dome after having lunch with former teammate Torii Hunter and dropping the Angels' new center fielder off for Wednesday's game.
As for the 34-year-old Koskie, just being down on the field at the dome without having any problems was something that he considered to be a big step.
Wednesday was the first time that Koskie had been back at the ballpark since last June, when the Brewers were in town to play the Twins. At that time, he could not stay very long before he felt dizzy and nauseous and had to go back home.
Koskie said he has come a long way since then. He's now able to drive without any problems and to play with his three sons -- ages 3, 5, and 7 -- without any problem.
Still, Koskie has not been able to resume normal workouts and he said he won't even think about making a comeback until that happens.
"I want to get to the point where I'm symptom free and I can go out and exercise as normal," Koskie said.
It's been nearly two years since Koskie was last on a baseball field. He suffered his concussion on July 5, 2006 when he chased down a shallow popup while playing for the Brewers. He did not hit his head on the play, but the effects of the concussion he suffered has been lingering ever since.
That means getting dizzy and nauseous at times, and Koskie said it's not necessarily during just physical activity. He can be watching hockey on TV or a fast-paced television show when the symptoms develop. But he's learning better how to deal with the situation.
Koskie said that his recovery time has increased. While a year ago, the symptoms lingered for as long as a month, Koskie said now the symptoms can go away almost immediately if he removes himself from the situation.
But what that means for his baseball career is still uncertain. Koskie feels like he's still in a bit of limbo. He's seeing progress in his ability to do everyday activities, but it's not enough to move completely forward.
"I don't know if I'm going to wake up one day and it will all be gone," Koskie said. "Or if there is going to be some stuff that's lingering and I have to deal with it the rest of my life. I just don't know."
Koskie became a free agent this past fall when the Brewers declined their 2008 option on his contract. Whether any teams would be willing to take a chance on the 34-year-old, once he's fully recovered, is also uncertain.
And until Koskie knows what his future entails, being around baseball is tough. Just how much he misses the game was clear from the look on his face, and he even declined the chance to go lean on the batting cage and talk to some of the Twins as they took batting practice.
"I'm not going to lean on the cage until I'm retired or I've got a uniform on," Koskie said. "Right now, I'm in this kind of halfway thing. I would still like to play baseball, but physically, I'm not able to right now."
