* The Chicago Cubs are getting a new pitcher named Yosver Zulueta from another team called the Seattle Mariners. This is like when you trade a toy with a friend to get a new one for your collection.
* The Cubs are playing the Colorado Rockies soon, and this new pitcher might help them play even better. It's like getting a new player for your team right before a big game.
* Yosver Zulueta hasn't played a lot in the big leagues yet, but the Cubs think he can help them. They are giving the Mariners some money and a player from their minor league team to get him.
