Pitcher Armando Galarraga #58 of the Detroit Tigers covers first base as Jason Donald #16 of the Cleveland Indians steps on the bag while umpire Jim Joyce watches on June 2, 2010 in Detroit, Michigan. Donald was called safe by Joyce, in what would have been the last out of a perfect game thrown by Galarraga.

Baseball Commissioner Bud Selig won't reverse an umpire's admitted blown call that cost Detroit Tigers pitcher Armando Galarraga a perfect game, according to a report Thursday.

Selig says Major League Baseball will look at expanded replay and umpiring, but not the botched call Wednesday night.
