Carpenter's return to booth TBD for 2013

WASHINGTON -- Nationals play-by-play announcer Bob Carpenter is in the last year of his contract with Mid-Atlantic Sports Network, and it's not known if he will be back with the team for the 2013 season.

According to a baseball source, the Nationals and MASN have told Carpenter they will not talk about a contract until after the postseason. Carpenter declined to comment about his future with the club.

Carpenter has been with the Nationals since 2006 and is known for the catch phrase, "See -- you -- later," whenever a Nationals player hits a home run.
