Bordick and Physioc join the announcing team of Ernie Johnson, Ron Darling and Cal Ripken Jr., and field reporter Matt Winer.
"TBS looked at a number of commentators with connections to Baltimore and Kansas City and decided to go with Mike Bordick and Steve Physioc because of their broadcast experience and their strong ties to each team," Turner Sports spokesman Eric Welch said.
The decision to include local broadcasters stemmed from the success of "Teamcast" during the NCAA Final Four on TBS, during which team-specific presentations tailored to the individual teams were included in addition to the traditional telecast. Under the banner "Your Team, Your Way," the telecast was presented with unprecedented local flavor that included team and player storylines.
No one knows the playoff teams better than those who have watched every game from Opening Day through the end of the season, so including local broadcasters to enhance the national telecast during the ALCS makes sense.
Right now, TBS is focusing on Games 1 and 2 and will make a determination after that if it will continue using local broadcasters on telecasts.
Physioc just completed his third season with the Royals, serving both as a voice on the Royals Radio Network and as a play-by-play broadcaster for 55 regular-season games on FOX Sports Kansas City.
Prior to that he spent 14 seasons (1996 to 2009) with the Los Angeles Angels as the television play-by-play voice on FOX Sports West and KCOP. In addition to his television duties, he worked on the Angels radio broadcasts on AM 830.
Bordick, a longtime Oriole and Orioles Hall of Famer, joined the MASN broadcast team in 2012, pairing with Jim Hunter or Gary Thorne as an analyst for several Orioles telecasts.
