DENVER — The Atlanta Braves have sent undefeated rookie Tommy Hanson to Class-A Myrtle Beach and called up right-hander Luis Valdez from Triple-A Gwinnett.

The Braves said the move was made to add bullpen depth for their weekend series in Colorado, and Hanson made his final start before the All-Star break Friday.

Hanson is 4-0 with a 2.85 ERA through the first seven starts of his career. He can be recalled in time to make his first scheduled start after the hiatus.

Valdez has 16 saves and a 3.00 ERA in 37 games for Gwinnett.
