Most players find it annoying, if not upsetting, to be traded to a new team in the middle of a season. For a while, they're surrounded by strange faces and, often, are thousands of miles from their family and friends.

The trade that sent him from the Milwaukee Brewers to the Angels last July was his second trade, but the first in the middle of a season.
