By beating the Yokohama Bay Stars 13-5 last night, the Swallows became just the 3rd team to go from being 19 or more games under 500 to a team at 500 (during the course of a season). The other two teams: the Hanshin Tigers in 1966 (19 games under, ultimately finished season 2 games under 500 and in third place) and the Nakai Hawks in 1962 (20 games under, ultimately finished season 16 games above 500 and in second place).
This also betters the Swallows' previous mark of going from 15 games under 500 to 500 in 1972 (ultimately finished season 7 games under 500 and in fourth place).
The Nippon Ham Fighters have also turn their season around, going from 14 games under 500 to their current 2 games over 500 record. This is also the first time in NPB history that two teams managed to make a return to 500 after being 14 or more games under 500 (during the course of a season).
In addition, of the 6 teams in NPB that have managed a return to 500 after being down 14 or more games under 500, five managed to finish in third or better.
On a side note: Junji Ogawa is 41-22-1 since taking over the Swallows. It should also be mentioned that the offense has gone from scoring 3.13 runs a game (during Shigeru Takada's reign) to 5.31 runs a game (during Ogawa's reign). A large part of that could be attributed to the addition of Josh Whitesell (41 G, 46-for-140, 12 double, 1 triple, 11 homers, 36 RBI, and a 1.105 OPS).
