ATLANTA — Former Atlanta Braves pitcher Tommy Hanson, once considered among baseball’s most promising young talents before being beset by shoulder injuries, has died in Atlanta at age 29, the team said on Tuesday.

The Braves said Hanson died Monday night at a local hospital. Atlanta television station WSB said he suffered “catastrophic organ failure” after first being hospitalized on Sunday after suffering breathing difficulty and falling into a coma. The station said it was unclear what triggered his illness.

“We are incredibly saddened to learn of Tommy’s tragic passing,” Atlanta Braves President John Schuerholz said in a statement. “He was a favorite in the clubhouse and with our staff and he will truly be missed by everyone in Braves Country.”

The 6-foot-6 Hanson pitched four seasons with the Braves, finishing third in the 2009 National League Rookie of the Year balloting. After suffering shoulder injuries, he was traded to the Los Angeles Angels in 2012.

In four seasons with the Braves and one with the Angels, Hanson had a career 49-35 record with a 3.80 ERA in 123 games.

Earlier this year, he signed a minor league contract with the San Francisco Giants.
