4 pm: Muñoz has been designated for assignment, the team announced. Reliever Enyel De Los Santos was activated from the IL to take Muñoz’s spot on the roster. Infielder Isaac Paredes is also back from the bereavement list. Shay Whitcomb was optioned to Triple-A.
1:45 pm: The Astros have placed Rule 5 pick Roddery Muñoz on outright waivers, reports Chandler Rome of The Athletic. Players can be placed on waivers while remaining on the 40-man roster but it seems likely that the Astros plan to cut the right-hander. If any club claims him, they would also be bound by the Rule 5 parameters. If he clears waivers, he would have to be offered back to the Reds, who could assign him to the minors without putting him on the 40-man roster.
Muñoz was an unusual Rule 5 selection. Most guys taken in that draft have been in the minors for a few years without getting a big league shot. Muñoz had already seen a notable amount of time in the majors, having tossed 93 2/3 for the Marlins and Cardinals. He didn’t have much success, however, with a 6.73 earned run average in that time. He exhausted his option years over the 2023 to 2025 seasons.
The Cards put him on waivers in November. The Reds claimed him, non-tendered him and re-signed him to a minor league deal. Shortly thereafter, the Astros grabbed him in the Rule 5. He had a good spring, striking out 16 opponents in ten innings. He did allow five earned runs but the punchouts were enough to get him an Opening Day roster spot. Unfortunately, he has been lit up to start the season. Through four innings, he has allowed seven earned runs. He racked up six strikeouts but also gave out six walks and threw two wild pitches.
Even if Muñoz weren’t out of options, he couldn’t be sent to the minors as a Rule 5 guy. It seems the Astros have run out of patience and will make a move. As mentioned, teams are allowed to place players on waivers while keeping them on the active roster, so it’s possible Muñoz could still be with the club tonight. However, it’s also possible he gets designated for assignment before game time to make way for someone else.
Rule 5 guys can be traded or claimed off waivers. If any other team takes a shot on Muñoz, they would be bound by the same Rule 5 parameters. If he clears waivers, he’ll be offered back to the Reds. That club could send him to the minors as non-roster depth.

This guy is not supposed to be a major leaguer.
Yet he achieved that dream that we could only imagine. Who are you to limit others?
I was surprised when they claimed him on rule five draft. He does not have track an impressive track record .
Bit of a bewildering pick from the start. I think they’re the seventh org to try to harness his stuff before cutting bait.
Looks like most of the rule 5 guys won’t be sticking with their new teams
De Los Santos is a massive upgrade over Munoz.
if he doesn’t get the whiff (which to his defense is definitely a skill of his, with a 96 percentile in whiff rate (43+%), he gives up some hard contact (95.5 ave exit velo this year).
I get why teams are intrigued, esp with that slider. But opponents are hitting .368 against him and he’s giving out 24% free passes. Hard to get off the mound with numbers like that. I can’t see another team giving him a spot with what he’s done early this season with the Stros.
