The Angels just lost 3-0 in Seattle to fall to .500. The A's just lost 4-3 at home to the Twins in 10 innings.
Thus:
The Texas Rangers end the night in control of the AL West by a full game.
P.S. Oakland would also almost certainly be .500, as well, with the Rangers more than a game up if not for bizarre rain delay rules and impatient crew chiefs.
