Sept. 1 is a rather big day for fantasy baseball owners: New rookie blood will be promoted to the major leagues, and in some cases these hitters and pitchers will matter in fantasy. It happens every year on or around this date; just as minor league seasons come to an end, major league teams are allowed to expand their rosters, thus rewarding prospects.

The Cincinnati Reds won't wait until Wednesday for left-hander Aroldis Chapman. The team has already called him up to serve a role in the bullpen, and he could make his major league debut Tuesday night.
