So, you're looking for the Astros pitcher for tomorrow. Here is the thing. It is January 17, 2026. If you walk up to the gates of Daikin Park in Houston tomorrow morning expecting to hear the pop of a catcher's mitt or see a starting pitcher warming up in the bullpen, you’re going to be met with a very quiet stadium and maybe a confused security guard.
The MLB regular season doesn't start for another two months.
I know, I know. We all miss baseball. But right now, we are in the heart of the "Hot Stove" season, not the pitching season. While there isn’t a game on the schedule for tomorrow, January 18, the conversation around who will be the Astros pitcher for tomorrow—as in, the future of this 2026 rotation—is actually reaching a fever pitch. The roster looks wildly different than it did just a few years ago. No more Framber Valdez. No more Justin Verlander.
Honestly, the "pitcher for tomorrow" isn't a single guy; it's a massive question mark that GM Dana Brown is trying to turn into a semicolon.
The Imai Factor and the New Look Rotation
If we're talking about the guy who is going to be the "ace" when things actually kick off in March, it is Hunter Brown. Period. He’s the undisputed leader now. But the name everyone is whispering about in Houston right now is Tatsuya Imai.
The Astros basically stunned the league by snagging Imai on a three-year, $54 million deal earlier this month. It’s a classic Houston move: finding value where others see risk. Imai isn't Yoshinobu Yamamoto, but he’s got that high-spin repertoire that the Astros' pitching coaches usually turn into gold.
Think about the projected rotation for a second:
- Hunter Brown (The Ace)
- Tatsuya Imai (The New Weapon)
- Cristian Javier (The Wild Card)
- Spencer Arrighetti (The Sophomore Surge candidate)
- Mike Burrows (The Breakout)
Wait, what about Lance McCullers Jr.? That’s the $17 million question. He’s still on the roster, but after missing basically... well, forever... nobody knows if he can actually hold down a spot. Some people think he’ll end up in the bullpen. Others think he’s the secret sixth man.

Why a Six-Man Rotation is Actually Happening
There is a lot of chatter around Minute Maid—wait, it’s Daikin Park now—about Joe Espada moving to a six-man rotation.
It makes sense. You've got Javier coming back from injury. You've got Imai adjusting to the MLB schedule from Japan. You’ve got young arms like Ryan Weiss (back from Korea) and AJ Blubaugh who need innings but can’t be rode like workhorses.
If they go with six, it changes everything for fantasy owners and bettors. It means your favorite Astros pitcher for tomorrow might actually be "the bullpen" more often than not. The days of 200-inning seasons for this staff are probably over. They are leaning into the "quality over quantity" vibe, relying on a back-end gauntlet of Josh Hader and Bryan Abreu to finish what the starters begin.
What to Watch for in the Coming Weeks
Since there isn't a game tomorrow, what should you actually be doing?
Keep an eye on the injury reports for Ronel Blanco and Hayden Wesneski. They are both projected to start the season on the IL, but their recovery timelines will dictate how much pressure is on the young guys like Arrighetti early on.
Also, don't sleep on Ryan Weiss. The guy was dominant in Korea last year, and the Astros have a history of taking "reclamation projects" from overseas and turning them into high-leverage starters. He might be the most underrated piece of this entire puzzle.

Actionable Next Steps for Astros Fans
Even though the mound is empty tomorrow, the prep work isn't. Here is how you should handle the "no game" reality of January:
- Check the Spring Training Schedule: The first actual game is February 21 against the Nationals. That is when you’ll see the first real "pitcher for tomorrow."
- Monitor the 40-man Roster: The Astros are still "thin" according to some analysts. If Dana Brown makes another trade for a veteran arm (rumors are still swirling about Freddy Peralta), the rotation order gets shuffled immediately.
- Adjust Expectations for Javier: Don't expect 2022 "El Reptil" right out of the gate. He’s a "wait and see" guy for the first month of the season.
The Astros pitcher for tomorrow might not be throwing a 98-mph heater at a target right now, but the front office is certainly playing a high-stakes game of chess to make sure someone is ready when the lights finally come up in March.
Stay tuned. The rotation battle in West Palm Beach is going to be a bloodbath.
