The Atlanta Braves moved to add depth to their pitching staff on Wednesday by acquiring righthanders Lance Cormier and Oscar Villarreal from Arizona in exchange for catcher Johnny Estrada. The deal was to be formally announced at 4 p.m. Cormier, a 25-year-old who played collegiately at Alabama, went 7-3 with a 5.11 ERA in 67 appearances for Arizona last season. Villarreal, who just turned 24, was 2-0 with a 5.47 ERA in 11 games in 2005. Estrada was Atlanta's starting catcher last season, but the emergence of Brian McCann in the latter half of the season made the veteran expendable. He hit .261, and was not as effective at the plate or behind it following a homeplate collision with the Angels' Darren Erstad in June. Estrada was acquired by the Braves in 2003 from the Phillies in exchange for Kevin Millwood.
