If the Houston Astros fail to qualify for the postseason, they can point to the Athletics as a prime reason.
Houston has dropped its past six meetings with the Athletics and is just 4-7 overall as the teams continue a three-game series on Wednesday night in West Sacramento, Calif.
The latest painful result was Tuesday's 5-1 setback when the Astros had just three hits.
The defeat was Houston's fourth straight and leaves the club one game behind the Detroit Tigers for the final American League wild-card berth.
The Astros also are four games behind Seattle in the AL West with five games left. The Mariners also hold the tiebreaker after posting a three-game sweep of Houston over the weekend and will clinch the division with either their next win or the next Houston loss.
