NEW YORK -- Baseball's owners have approved changing the format of this year's AL and NL Division Series from a 2-2-1 format to a 2-3 format, giving the team with home-field advantage the last three games of the five-game series.
The change, approved by owners on Thursday, was made to accommodate baseball's new one-game, wild-card playoff round. The new round of playoffs was added after schedules were set with the regular season ending Oct. 3 and the World Series starting Oct. 24.
Teams with home-field advantage will host Games 3, 4 and 5, eliminating one travel day, and the wild-card playoff winners will start the division series at home. The division series matching the Nos. 2 and 3 seed will begin Saturday, Oct. 6, while the matchup involving the No. 1 seed and the wild-card winner is scheduled to start Sunday, Oct. 7, according to a source.
