The Houston Astros arenāt exactly short on ambition this offseason, but one of their most practical roster upgrades might come from a place fans arenāt expecting:
The waiver wire.

Outfielder Michael Siani was just designated for assignment by the New York Yankees, making him available on waivers ā again. And if that sounds familiar, itās because this has basically been his winter story: DFA, claimed, DFA, claimed⦠repeat.
Now Houston has a chance to step in and do something simple, sneaky, and potentially very useful.
Not because Siani is some hidden offensive breakout waiting to happen.
But because his glove might change games all by itself.
Michael Siani is available⦠and the Astros can take advantage

Siani, 26, has now been designated for assignment by multiple teams this offseason after originally being DFAād by the St. Louis Cardinals.
From there, he bounced to:
- Atlanta Braves
- Los Angeles Dodgers
- New York Yankees
And now heās back on the waiver carousel again.
This isnāt random chaos. Itās roster math.
Teams make these moves because theyāre trying to squeeze players through waivers so they can outright them to Triple-A and keep depth without using a 40-man roster spot.
But that strategy only works if nobody else claims the player.
And thatās where Houston comes in.
If the Astros claim Siani now, they donāt just add a defender ā they also block the Yankees from stashing him in the minors for free.
The reason Houston should care: Sianiās defense is the real deal

Letās be honest about what Siani is and isnāt.
He isnāt a middle-of-the-order bat.
He isnāt a hidden power threat.
He isnāt going to solve Houstonās lineup questions.
But defensively?
Heās a legitimate impact player.
In only 160 career MLB games, Siani has already put up:
- 7 Defensive Runs Saved (DRS)
- 17 Outs Above Average (OAA)
Thatās the kind of profile teams usually pay for ā especially when the margins in October come down to one misread ball, one bad jump, one extra base.
And Houston knows that better than anyone.
For a team thatās constantly built around pitching efficiency and run prevention, adding an elite glove in the outfield isnāt āextra.ā Itās insurance.
Itās a way to steal outs that other teams donāt.
The brutal downside: Siani canāt hit (and everyone knows it)

Hereās the part that keeps Siani from being a stable big-league roster lock:
He simply hasnāt hit.
His career offensive profile is rough:
- 2 career home runs
- .547 career OPS
Thatās not āneeds work.ā Thatās borderline unplayable offensively over a full-time role.
And itās why he keeps getting DFAād even though teams clearly like him.
They want the defense ā but they canāt justify the roster spot when injuries hit, when they need flexibility, or when theyāre trying to protect bats.
Why the Astros should still do it: itās low risk, high leverage

This is what makes Siani interesting for Houston:
The cost is almost nothing.
If the Astros claim him and it doesnāt work out, the worst-case scenario is extremely clean:
- He looks overmatched offensively in camp
- Houston DFAās him
- They lose a week of spring training reps
- Thatās it
But if it does work?
Or if they can sneak him through waivers later and stash him as depth?
Houston suddenly has a defensive weapon available for:
- late-inning substitutions
- protecting leads
- extra-inning games
- emergency center field coverage
- matchup-specific roster decisions
And that matters more than fans want to admit, because the Astros arenāt trying to win games 11ā9.
Theyāre trying to win games 4ā3.
The quiet truth: this move isnāt flashy⦠itās smart

Astros fans are understandably focused on bigger names and bigger bats. But teams that win consistently donāt just chase stars ā they build edges.
Michael Siani is an edge.
Not because he changes the lineup.
Because he changes whatās possible defensively in the late innings ā the kind of shift that doesnāt show up in headlines until it saves a season.
And if Houston can grab that for the cost of a waiver claim?
Thatās the kind of move serious contenders make while everyone else is watching the spotlight.
