By my estimates we could have as many as six new managers patrolling the dugouts in Major League Baseball next year. Teams such as the Marlins, Mets, Indians, Red Sox, perhaps the Marinerscould be looking for a new skipper. The Houston Astros have been in the market since firing their manager  Brad Mills back in August. That opening will be filled with Washington Nationals bench coach Bo Porter.

The Astros will make it official today that Porter will help lead the team into their new American League home next year.

Porter will stay with the Nationals through the end of the postseason no matter how long that lasts for the team. Porter was reportedly one of four finalists for the gig, including their interim manager  Tony DeFrancesco.

This has been a brutal season for the Astros, who currently have baseball's worst record at 51-105.

Next year, Houston gets relocated to the AL West and we get more interleague games as all divisions and leagues will be balanced out.

Porter spent a short time in the big leagues, playing 89 games from 1999-2001 with the Cubs, A's and Texas Rangers.

Porter currently serves as Nationals bench coach for Davey Johnson who has led the Nationals back to the postseason for the first time since they were the Montreal Expos.

Reports say Porter beat out Tampa bench coach Dave Martinez and Red Sox bench coach Tim Bogar for the job.
