According to Brian McTaggart the Astros are planning on calling up Fresno's Danny Worth today.
As Jake Kaplan notes, the Astros will face Cardinals lefty Jaime Garcia tonight, and then two lefties this weekend against the Reds.
Worth has a career .230/.293/.295 major-league slash line in 135 games for Detroit from 2010-2014, but he has been straight killing it for Fresno, hitting .340/.449/.550 with 43K:37BB in 54 games this season.
Against lefties at Fresno this year Worth is hitting .396/.467/.717, with eight extra-base hits in 60 plate appearances.
Of course, the question is who will be the corresponding move.
