PHOENIX - Major League Baseball's trade deadline arrived more than 10 days ago, but it doesn't mean major league teams are finished shopping for roster upgrades. The Phillies traded for a vital piece of their 2008 championship run in August: home-run hero Matt Stairs.
Teams can still trade for players this month - and have them eligible for postseason play - if they consummate a deal before Sept. 1. The catch is those players must be moved through waivers - either in getting claimed off waivers, claimed and traded for, or passing through waivers and then traded.
