With Josh Reddick back and hitting home runs, the Oakland Athletics are bringing some more muscle and a bigger lead into a crucial weekend series. Reddick homered and had three RBIs, A.J. Griffin allowed just two hits in seven innings, and the A's beat the Minnesota Twins 8-2 Thursday afternoon to increase their division lead to 3 1/2 games over idle Texas in the American League West. It is Oakland's largest lead over the Rangers since Aug. 3. The teams are to scheduled play a three-game series this weekend in the Lone Star State.
