Jesse Chavez struck out six over eight innings to win for just the second time in six starts, and the Oakland Athletics beat the National League West-leading Los Angeles Dodgers 5-2 on Wednesday for a two-game sweep. Billy Burns hit a tying double for Oakland in the sixth then scored the go-ahead run on Danny Valencia's double-play grounder two batters later. After the low-budget A's won 5-4 in 10 innings Tuesday night, they beat baseball's biggest spender again to win consecutive games following a seven-game skid on a recent road trip through Toronto and Baltimore.
