September is an exciting time for sports fans. Playoff races are heating up, friends argue about whether the White Sox can hold off the Tigers in the AL Central, and fantasy owners scramble for every last edge before playoffs begin.
On that last point, owners race to the waiver wire every time a big-name prospect gets the call. While more teams are exhibiting a patient developmental approach with their future starts (e.g. the Orioles and Dylan Bundy or the Royals and Wil Myers) there are several recognizable names joining big league clubs as rosters expand.
Not all the players on this list are for every league. Some will only be useful in deeper leagues, but all of these players have the potential to be useful as you finalize your roster and look to a title run.
