Oakland's Nick Swisher and Milton Bradley each homered in a four-run second to back Rich Harden's five shutout innings, helping the A's clinch the AL West title Tuesday night with a 12-3 victory over Seattle. The win, combined with the Angels' 5-2 loss against the Rangers, gave Oakland its first division title since 2003 and the 14th in franchise history. The small-budget A's are back in the playoffs after a two-year absence thanks to a sensational second half, a hallmark for this club in recent years.
