Shulman was voice of ESPN's "Monday Night Baseball" for the past three seasons and has been part of ESPN's Major League Baseball and college basketball coverage since 1995. A native of Canada, he has also been involved in NBA coverage and provided play-by-play for Blue Jays games on The Sports Network (TSN) in Canada from 1995-2001.
Hershiser, the 1988 National League Cy Young Award winner, is returning as a "Sunday Night Baseball" analyst for his second season, and Valentine is new to the booth.
Valentine, who managed the Mets and Rangers in the Majors and Chiba Lotte Marines in Japan's Pacific League from 2004-09, was an ESPN studio analyst last year.
The trio will replace Jon Miller and Joe Morgan, who broadcast the network's Sunday night games together for 21 years.
"Dan has broad knowledge of the game, an ability to articulate baseball's analytics and a conversational tone which will bring out the best in our analysts," ESPN executive vice president of production Norby Williamson said in the network's official press release. "Pairing him with Orel Hershiser, who made great contributions in the 'Sunday Night Baseball' booth last season, and the unique opinions and fresh perspective of Bobby Valentine, will make for a dynamic 'Sunday Night' team."
