Astros roster moves: Josh Fields activated from DL, Jonathan Villar optioned to Triple-A

Nothing has gone according to plan with this Astros roster. Maybe that's a good thing. The latest unorthodox decision came late Wednesday evening, when the Astros recalled Josh Fields from the 15-day disabled list and optioned backup infielder Jonathan Villar to Triple-A.

With the move, Houston will have 13 pitchers on the roster and just 12 position players. That includes only one backup infielder (Marwin Gonzalez) and one backup outfielder (Robbie Grossman).

Villar hit .077/.200/.077 in 15 plate appearances over seven games. He had one run scored and one stolen base, often filling in at third base for the Astros.

Fields' original roster spot was taken by reliever Will Harris, who Houston nabbed from the Diamondbacks in the offseason. Harris hasn't allowed a run in eight innings, striking out nine and walking three.

Fields has been dealing with a groin injury since late March. He made a few rehab starts for Triple-A Fresno before the Astros moved to bring him to the majors. The team could have held him down for up to 30 days, but chose to bolster the bullpen before the trip to Oakland.

What do you think? How long will the Astros keep the roster this way? Who's gone once Brett Oberholtzer is healthy? (Sorry, Wojo fans, it's probably him).
