Houston manager A.J. Hinch went back to the drawing board after another loss to the Texas Rangers on Sunday at Minute Maid Park.
``We have to find a new approach against them,'' Hinch told reporters.
What the Astros have been trying over the last two seasons is not working. The Rangers have swept a pair of three-game series this season and have won 14 of their last 16 games against the Astros. The Rangers have out-scored the Astros by 27 runs in the 16-game stretch.
Houston has had a lead in only one game against the Rangers this season.
