As part of the new collective bargaining agreement, MLB has some new rules. Some will have major effects on the sport, including playoffs, scheduling and free agency. Others are mere footnotes. This is in no way one of the mere footnotes.

Playing a split double-header scheduled at least 48 hours in advance, the Pirates and the Rockies became the first teams eligible to add the mythical 26th man to their rosters, a new allowance for teams facing twin bills. It's meant to offer teams a little bullpen relief and end the silly practice of teams making roster moves between games, but for Pittsburgh's Jared Hughes and Colorado's Zach Putnam, it means the world. And probably being sent down tomorrow.
