It appears the Houston Astros are preparing to recall pitchers Jordan Lyles and Dallas Keuchel from Triple-A Oklahoma City, MLB.com reports by way of a baseball source.

Although general manager Jeff Luhnow was not available for comment, it seems one of those pitchers could take Brad Peacock's vacated spot in the rotation Thursday against the Tigers. The corresponding roster moves were not announced.  

The 22-year-old Lyles was strong in his latest start at Triple-A and was slated to begin the year in the rotation before he struggled in the spring.

The 25-year-old Keuchel was recalled April 6 and had a 3.38 ERA over 10 2/3 innings in relief before being sent back down.
