Christian Roa elects free agency after Cubs outright him through waivers

Christian Roa, a right-handed reliever who spent the better part of this season shuttling between Triple-A and the waiver wire, has chosen free agency over a minor league assignment from the Chicago Cubs, per MLB.com's transaction tracker.

What happened

The Cubs sent both Roa and fellow reliever Eduarniel Núñez through outright waivers on Wednesday, according to MLB.com. Both pitchers had been designated for assignment a week earlier. Roa, who has been outrighted multiple times across his career, exercised his right to decline the minor league assignment and enter the open market. Núñez, clearing outright waivers for the first time, does not yet have that same right and will remain in the Cubs organization.

The distinction matters in ways that are easy to overlook. Under general league mechanics, a player who has been outrighted before accumulates the right to refuse a subsequent minor league assignment and walk. A first-time outright clears waivers and lands wherever the club directs. Roa has been here before. Núñez has not — at least not until now.

Both pitchers were in-season waiver claims by Chicago, which means neither arrived through a trade or a free-agent signing. They were picked up, used, and ultimately moved on from through the same mechanism that brought them in.

Why it matters

Roa's path through the 2026 season reads like a tour of the American League's middle-relief depth charts. He began the year with his hometown Houston Astros, then passed through the Minnesota Twins and Baltimore Orioles before landing with the Cubs. That is four organizations in a single season, all via the waiver process — a reminder of how fluidly the back end of a 40-man roster can move when a player is not sticking at the big-league level.

The Cubs' decision to designate both pitchers a week ago, and the subsequent clearing of waivers, suggests the rest of the league passed on claiming either one. That is its own data point. Roa's numbers this year — at both levels — gave clubs plenty to weigh.

The numbers

Roa's major league work this season came entirely with Houston: 8 2/3 innings, 5 runs allowed, 7 walks issued, and 3 batters hit. That walk rate, applied across fewer than nine innings, is the kind of line that tends to end a big-league stint quickly, and it did.

His Triple-A numbers were not a refuge. Per MLB Trade Rumors, Roa surrendered 17 runs over 15 1/3 frames at the Triple-A level, issued 10 more free passes, and gave up 21 hits. The walks did not stop when the competition stepped down a level. For a reliever whose primary job is to get through an inning without the bases filling themselves, that combination is difficult to overlook — and, apparently, difficult to claim off waivers.

Where the club stands

The Cubs sit at 89-73 (.549), good for 2nd place in the NL Central, 14 games back in the division. They are ranked 2nd in the Wild Card standings, sitting +1.0 relative to the cut line, and have won their most recent game. The division race is no longer in play. The Wild Card margin is what Chicago is managing now, and every roster decision — including which relievers occupy the back of the 40-man — carries weight in that context.

The Cubs enter a three-game home series against the St. Louis Cardinals at Wrigley Field this weekend with that +1.0 Wild Card cushion intact. David Peterson is the probable starter Friday against Andre Pallante. Shota Imanaga takes the ball Saturday opposite Kyle Leahy. Javier Assad is lined up for Sunday against Matthew Liberatore.

A one-game edge over the Wild Card cut line is comfortable enough to breathe, not comfortable enough to exhale. A bullpen that has been cycling through waiver claims and DFA decisions is not unusual for a club managing a roster in July, but the Cardinals series arrives at a moment when the wins need to matter.

Núñez, who cleared waivers and stays in the organization, remains a piece of that bullpen depth picture — at whatever level the Cubs assign him. His situation is worth monitoring as the roster continues to take shape heading toward the late-season stretch.

What we don't know yet

MLB Trade Rumors does not specify where Núñez will be assigned within the organization now that he has cleared outright waivers. That detail is pending.

It is also not reported whether Roa has drawn interest from other clubs since entering free agency. He is now free to sign with any organization, but no deal has been reported.

MLB Trade Rumors notes that Roa had impressed in Astros camp — though the passage in the report is incomplete, leaving the full context of that impression unreported. What can be said is that the season did not sustain whatever that early promise was.

What to watch

The Cubs' Wild Card position — currently +1.0 relative to the cut line — is the number that will drive roster construction decisions for the rest of the summer. As the 40-man continues to shift, the question of which relievers earn a spot on the active roster becomes more pointed. Under general league rules, clubs carry 26 players on the active roster through the end of August, with that number expanding to 28 from September 1 onward. That expansion is still weeks away, but clubs begin planning for it now, and depth decisions made in early July have a way of looking either shrewd or hasty by the time rosters open up.

For Roa, the question is simpler: whether another organization will see something in the underlying profile worth a look. The walk totals at both levels this year make that a harder sell than it might have been in a different campaign. He is 27, per MLB Trade Rumors, and has now been through the outright process enough times to know exactly when to use the exit.

Núñez's situation is the quieter subplot. He stays, clears waivers for the first time, and now has a data point in his organizational history that he did not have a week ago. Whether that changes how the Cubs use him — or how other clubs view him the next time he surfaces on the transaction wire — is the thread worth following.

The Cardinals series starts Friday at Wrigley.
