Which baseball team has been the biggest disappointment and which team has been the biggest surprise?

I agree with you on the Cleveland Indians and Boston Red Sox. In the past years the Red Sox was good, and it was the Cleveland Indians were losing. And now this year they are on top of the Central division just like the Reds did last year. I hope that this doesn't become like Cinderella, and the cock strikes midnight on them. I not sure about any players that have surprised me, but I do say that it is quite the surprise that Cleveland Indians are winning so far this year, even through the season is still young, but I hope that it can carry for the whole season, it would be nice to seem them make it to the playoffs for a change.
