Houston has made a roster move on Monday, sending struggling starting pitcher Asher Wojciechowski to Triple-A Fresno and recalling hot-hitting outfielder L.J. Hoes to take his spot.

Astros are going to call up OF L.J. Hoes & option RHP Asher Wojciechowski to Fresno. That gives them extra position player for Padres series — Brian McTaggart ⚾️ (@brianmctaggart) April 27, 2015

Technically, Tags, it doesn't give them an "extra" position player. It gets them back to 13 position players, which is what a lot of teams have. I'd call that a "normal" number of position players.

At any rate, the move is surprising on one hand and unsurprising on another. Asher Wojciechowski hasn't been good in his four big league games. He has failed to make it out of the fifth inning in any of them.

In 16 innings, Wojo has a 7.31 ERA and an 0-1 record. He struck out 16 in that time with seven walks and two homers allowed. His . 396 BABiP probably would fall eventually and you would think that'd mean his ERA would fall toward his FIP of 3.99 given more time.

But, his lack of success coupled with Bret Oberholtzer's health meant his days in the rotation were numbered .

The surprising move was calling up Hoes. Of course, after Luhnow took to Twitter to call out Little Jerome, we shouldn't have been too surprised.

Also, @MRLJHOES2U has been tearing up the PCL... hitting . 418 with a 1.076 OPS in 55 at bats. — Jeff Luhnow (@jluhnow) April 27, 2015

Hoes also has some positional flexibility if Marisnick's injury acts up again, though he's probably sticking on the corners.

Does this put to bed any thoughts that Hoes got buried because he was the "leak" last year? The only outfielder other than him on the 40-man is Domingo Santana, so it makes sense that he's the choice there.

But, did they need another outfielder? They could just as easily have recalled Ronnie Torreyes in a super-utility role.

It's an intriguing move, no matter how you look at it. What do you think? Was Hoes' hot start enough to recall him or do the Astros have concerns about how their outfield will hold up in the coming weeks?
