The MLB Network added yet another piece to their ever-growing puzzle of reporters and analysts today, by hiring FOX Sports’ Ken Rosenthal. According to MLB-N PR, Rosenthal will continue to work for Fox Sports, both online and on-air….

MLB Network today announced that Ken Rosenthal has joined its roster of on-air talent. Rosenthal will join the cast of MLB Tonight beginning Tuesday, June 30 at 6:00 p.m. ET. Rosenthal, who will continue his reporting for and MLB on Fox, joins Sports Illustrated senior writers Tom Verducci and Jon Heyman as Baseball Insiders on the MLB Network team.

“Ken brings a wealth of on-air reporting experience and insight into the game and we’re excited to welcome him to MLB Network,” said Tony Petitti, president and CEO of MLB Network. “As we grow as a network, it’s important that we continue to bring fans the most up-to-date information from the best resources in the business.”

Rosenthal has served as lead field reporter for MLB on Fox since 2005. Prior to joining Fox Sports, Rosenthal worked as the national baseball writer for The Sporting News and as a sportswriter at the Baltimore Sun, where he was named Maryland Sportswriter of the Year five times by the National Sportscasters and Sportswriters Association. He is a voting member of the Baseball Hall of Fame.

I still think Ken Rosenthal is a hypocrite after his Outside the Lines tirade during the whole “Ibanez Steroid Speculation” thing, but this is another big get for the MLB Network. Unlike the NFL, Major League Baseball only has one or two connected national reporters. Tom Verducci is one of them, and Rosenthal is the other. Both are now employed by the MLB Network.

In other Rosenthal news, be sure to Twitter him questions during the All Star Game. The reporter will be answering them during his time in St. Louis.
