Ken Rosenthal, who provides reports from the stands and elsewhere, will answer viewer-submitted questions between his on-camera appearances during the game July 14. He will also use Twitter as a venue to offer thoughts and opinions during the coverage.
Many believe the promise of Twitter is interactivity with those -- be they celebrities or simply people at work -- who were previously unavailable.
Fox Sports president Ed Goren called Twitter "a communications phenomenon that continues to grow. Our hope is that those who follow us on Twitter" will have a deeper connection with the broadcast.
Rosenthal, who is also becoming an on-air personality for the MLB Network, may be offering a template for sportscasters going forward: reporting on-air, as well as via Internet sites Twitter, Facebook and MySpace.
"I'm sure time will permit me only a few on-air opportunities during the [All-Star Game], so this gives me a forum to answer as many questions from fans as possible and report more of what I learn and observe," Rosenthal said.
