McKay is now on Dale Sveum's coaching staff and players have raved about his expertise and coaching. Friday will be the Cardinals' home opener and they will raise a banner celebrating the 2011 World Series win. On Saturday, the players will be presented with their rings.
It will be weird for McKay, 62, to not be wearing red.
"Most people say, 'Oh, it's just another game,' but it isn't," McKay said. "It's the Cardinals and the Cubs and I'm with the Cubs now. I'm looking forward to it. I hope we put on a good show. I gave them everything I had for 16 years, but that's baseball. Now I'm with the Cubs, and I'm going to give them everything I got."
McKay will take part in the ring ceremony. La Russa made a point of inviting him.
"You'll see a lot of red and one blue," McKay said of the players on the field.
He's eager to win a ring with the Cubs.
"I hope we can do some good things over here now," he said.
