With little over a month left to play, the remaining places to get an edge over your fellow owners are rapidly disappearing. Roster expansion in September certainly provides one such opportunity, with at least a few exciting prospects potentially getting the chance to earn a fair number of at-bats over the final few weeks.
Most of what happens when rosters expand is largely irrelevant to fantasy owners, though. Unplayable Orioles and Tigers losing at-bats to even more unplayable Orioles and Tigers won't effect too many competitive fantasy teams outside of those in the deepest of leagues. Neither will the influx of low-leverage relievers who will throw five or six innings over the course of the month.
One area where a small edge is possible (and potentially overlooked) is playing time. Not the playing-time split between players on a given team, which is important and widely discussed at every point in the year, but numbers of games to play for each team. At this point in the season, teams have surprisingly varying numbers of games left to play, with the Tigers playing 16 percent more games the rest of the way than the Angels and Blue Jays (36 for the former and 31 for the latter pair). That doesn't mean that every Tiger is suddenly interesting, but if there are equally mediocre Tigers and Angels or Blue Jays available on the waiver wire, there's little reason not to target the player who has the opportunity for 16 percent more at-bats.
