The trade worked out really great for us, but I'm sure that the Padres thought it was a decent deal at the time. They had a decent prospect (Alonso) at 1B, they played in a huge ballpark that hurts power hitters (Rizzo) and rewards pitchers (Cashner), and obviously had no way of knowing that Cashner would be injury prone. Cashner had just gone through an injury-plagued 2011, so there was at least a little reason to believe that was the case.
