Was there a player on your team that made you happy when he got traded, but made you feel bad later on?

Not this year, but a couple years ago when the Twins traded Matt Garza, I was pretty happy because he didn't seem like he was going to be that good. Then he had a pretty good year last season and I wished we had him back. Of course now he just threw a no-hitter, but on the other hand the guy the Twins got in the trade is having a career year, and that guy is Delmon Young. So I guess I was happy, then sad, and now happy again!
