Representatives of Major League Baseball’s 30 teams were back behind closed doors Thursday morning, first in a full meeting of all the owners and then in smaller discussion groups. They are expected to begin voting to select the next commissioner by early afternoon.

The owners filtered into the main meeting room at about 8:30 a.m. and split up less than an hour later. Orioles owner Peter G. Angelos arrived early.

MLB chief operating officer Rob Manfred, who is expected to be selected to replace retiring commissioner Bud Selig in January, arrived minutes before the meeting began.
