Play-by-play commentator Dave O'Brien and analyst Nomar Garciaparra will form the new ESPN "Wednesday Night Baseball" team for the 2011 season.

In addition, Sean McDonough will return to MLB in a season-long role as the play-by-play voice of "Monday Night Baseball," joined by analysts Aaron Boone and Rick Sutcliffe.

ESPN announced the changes Friday as it continues to revamp its signature Major League Baseball franchises.

In addition to their game responsibilities, Boone, Sutcliffe and Garciaparra will contribute to "Baseball Tonight" throughout the season.

O'Brien and Sutcliffe mainly called "Wednesday Night Baseball" games in 2010, with Garciaparra joining them for select telecasts.

Last season, ESPN's "Monday Night Baseball" commentator team included Dan Shulman and analysts Boone and Chris Singleton. Shulman will be calling "Sunday Night Baseball" telecasts this season with analysts Orel Hershiser and Bobby Valentine.

Singleton will be paired with play-by-play commentator Jon Sciambi on ESPN Radio's "Sunday Night Baseball" broadcasts.
