The last ten days have featured dozens of trades, and most of baseball’s 30 teams were responsible for a share of the action. But four clubs — the Orioles, Nationals, Mets and Padres — decided not to make trades. The Orioles (starting pitching, third base), Nationals (bench depth, starting pitching) and Mets (bullpen help) considered upgrades with 2012 in mind, while the Padres considered trading established players such as Chase Headley. In each case the clubs ultimately decided against making major trades.
Which of these teams, if any, should have made a move?
