On Friday, the Rangers maintained their advantage with a 7-4 win over the White Sox in which Mitch Moreland socked a pair of home runs and drove in five runs for the Rangers.
Not to be outdone, Torii Hunter did the same - two homers and five RBI - as the Angels knocked off Baltimore, 8-3.
The race bears watching, with the Angels having to make up significant ground on the Rangers, who lost in the World Series last season to the Giants. Only one team will likely make the playoffs, as LA is currently nine game behind Boston in the wild card race.
Rodriguez proved skeptics wrong again Friday, when he blanked the San Francisco Giants for eight innings, evening his record at 9-9 in a 6-0 Houston victory.
Allowing five hits and a couple of walks, Rodriguez struck out eight before turning the ball over the bullpen for the final inning, his second win in his last three starts.
The loss left the Giants 2 1/2 games behind Arizona in the West, as the Diamondbacks also lost, 4-2, to a red-hot Atlanta squad.
