Major League Baseball vice president Tim Brosnan has dropped out of the race to replace commissioner Bud Selig, CBSSports reported Thursday.

Brosnan was one of three finalists along with MLB chief operating officer Rob Manfred and Tom Werner, part owner of the Boston Red Sox. Brosnan has worked in the commissioner's office since 1991 and has been instrumental in every broadcast contract during the past 10 years.

Werner, 64, previously owned the San Diego Padres. Before then, he was the director of development for ABC. He is a member of the Television Hall of Fame.

Manfred has been Selig's deputy and his handpicked successor. He started in 1998 working full-time for MLB. Manfred has been instrumental in cleaning up the sport of performance enhancing drugs as well as labor negotiations.

A vote is expected sometime Thursday. To be elected, a candidate must receive 23 votes from owners of the 30 MLB teams.
