Astros general manager Jeff Luhnow said Thursday that the hope is that Jesse Crain (shoulder) will begin throwing off the mound sometime in the next 10 days. Crain is now recovered from the right biceps surgery he had last October, but he's still working on strengthening his shoulder. The Astros signed the veteran reliever for $3.25 million over the winter, but he's no lock to pitch in the majors this year.
