Fifteen major league teams still have a realistic shot at making the playoffs. Five of those teams will have their season end after game 162 of the regular season. Two others will be eliminated after the one-game Wild Card Games in each league. The remaining eight will then be cut down to four for the championship series, and then the final two will play in the World Series. Only one team will end the season on a high note.
After their elimination, non-champs will ponder the "what ifs" that could have changed the outcome of their season. If they were to look back to July and the potential trades that they passed on before the trade deadline, regret could follow when they realize that the roster weakness that did them in could've been addressed a couple months earlier.
Here is one trade that each of the 10 contenders (teams with the sixth to 15th best overall record) will regret not making at the deadline.
