Major League rosters “expand” to forty players on September 1. This means that the teams can carry up to that many players (as opposed to the twenty five man active rosters during the rest of the season). While it may help with having extra pitchers and introduce younger players to major league life, it also represents several opportunities for fantasy baseball players.
In those keeper leagues where you can pick up players this year and keep them on your team for next year (which shouldn’t be the case in September but that is another column) keep a sharp eye on those potential stars you can roster at a cheap price.
For those in redraft leagues the callups may present a speedy outfielder with fresher legs (Desmond Jennings, Tampa Bay or Brian Bogusevic, Houston) to get a few more stolen bases. Or it may mean a slugger (Yonder Alonzo, Cincinnati or Mat Gamel, Milwaukee) who could get enough at bats to add some home runs to a week spot in your lineup.
One player who arrived on the last day in August (important because that makes him eligible for post season playoff rosters) was Cuban pitching sensation Aroldis Chapman who joined the Cincinnati Reds and will presumably show off his 100+ mph fastball (he actually hit 103 on the radar guns in his first appearance yesterday) out of the bullpen.
Jennings, Alonzo, Bogusevic, Gamel, and of course Chapman represent the most important players called up today for those in keeper leagues. Perhaps on the way and of special interest would be Dustin Ackley, 2B, Seattle, Chris Carter, 1B/OF, Oakland, or perhaps even Jesus Montero, C, NY Yankees, so watch the transactions carefully.
