Padres manager Bud Black said Cashner will pitch March 30 at Petco Park. Black made the announcement before Cashner's fourth spring training start Thursday night against San Francisco.
''I think it's well-deserved, the way he pitched the second half of last season,'' Black said. ''You've heard me say it before: It's a feather in the cap for a pitcher to get an opening day assignment.''
In his first full season as a starter, Cashner went 10-9 with a 3.09 ERA last year. The right-hander appeared in 31 games, including 26 starts.
