Chris Johnson has started just one of the last five games for the Astros. Angel Sanchez made a third straight start at third base Friday and extended his hitting streak to eight games. Manager Brad Mills said he's discussed the situation with Johnson, who figures to continue to see limited playing time while Sanchez is hitting. Johnson is batting just .239/.281/.387 with six homers on the season. He's walked just 10 times while striking out on 72 occasions.
