Astros general manager Jeff Luhnow said Monday that a promotion to Triple-A Fresno is "imminent" for Musgrove, Jake Kaplan of the Houston Chronicle reports.

Musgrove is dominating Texas League hitters with a 0.34 ERA, 0.84 WHIP and 30:3 K:BB over 26.1 innings. Luhnow reiterated Monday that he's not afraid to promote pitchers from Double-A to the majors -- as was the case with Lance McCullers last season -- but he currently doesn't see an opening for the 23-year-old right-hander in the rotation. For now, the Astros will monitor Musgrove's workload so he's available to join Houston later in the year.
