Angels Outright Sammy Peralta and Sebastián Rivero to Triple-A Salt Lake

The Angels have cleared two roster spots by assigning left-hander Sammy Peralta and catcher Sebastián Rivero outright to Triple-A Salt Lake. Both went unclaimed on waivers and can elect free agency, which appears likely. The moves give the club room on its major league roster while leaving both players with a choice about where to continue their careers. An outright assignment sends a player off the active roster and into the club’s minor league system; when no other team claims him, the original club retains a route to keep him in organizational depth. That arrangement can suit a team trying to preserve options, but it doesn't guarantee the player will accept another minor league assignment. For Peralta and Rivero, the next decision is whether Salt Lake offers a better path than testing the market for a new opportunity.

Peralta’s uneven results

Peralta, 28, pitched 23 innings for the Rockies and Angels in 2026, posting a 6.65 ERA. That figure tells the story of his runs allowed, but it doesn't fully explain the quality of his work: his 20.5% strikeout rate and 8% walk rate were more encouraging, as was a 3.96 SIERA. The gap matters because ERA can swing sharply over a limited stretch, especially when a pitcher gives up home runs or has an unusually high share of balls in play fall for hits. Here, both factors worked against him. Peralta’s .417 batting average on balls in play indicates that a large share of those balls became hits, though that figure alone can't establish how much was bad fortune and how much reflected contact quality or defense. He also hit four of the 112 batters he faced, another part of a season that wasn't cleanly captured by the more favorable strikeout and walk numbers.

SIERA is an estimate built around outcomes a pitcher can influence more directly, including strikeouts, walks and home runs. It can offer a useful counterpoint to ERA, but it isn't a forecast or a guarantee that future results will improve. Peralta’s 3.96 mark gives a more favorable view of his 23 innings than his ERA does; the home runs remain a real concern, and the sample is small enough that neither measure should be treated as a complete verdict. This is more significant than it looks: a club assessing a depth pitcher has to decide whether the underlying skills justify another chance, even when the most visible result has been poor.

Across four major league seasons, Peralta has a 5.64 ERA in 68 2/3 innings. That record gives teams a broader view than one partial season, but it still covers relatively little work for a pitcher whose role may depend on matching up against particular hitters or filling a specific bullpen need. His fastball averaged 89.1 mph, while his sinker averaged 88.8 mph. Those velocities give context to the challenge he faces: pitchers without overwhelming speed often need command, movement, deception or a favorable matchup to keep hitters from doing damage. The source numbers don't establish which adjustment would help Peralta most, but his strikeout and walk rates offer a reason for teams to look beyond the ERA.

Rivero’s value behind the plate

Rivero, 27, appeared in 57 plate appearances for the Angels this season, batting .245/.286/.283. His career line across brief stints with Kansas City and Anaheim is .197/.247/.237 in 164 plate appearances. The sample is limited, but the broader record points to a clear constraint: his bat hasn't produced much in the majors. He’s struggled to hit in the minors, too, which makes it harder to argue that a larger offensive role is likely to change the picture. For a catcher, though, offense is only one part of the job. Receiving pitches, blocking balls, handling a pitching staff and controlling the running game can all affect whether a player remains useful even when his line at the plate is light.

Rivero’s defensive work has kept him in consideration as a reserve despite often sitting third or fourth on a team’s catching depth chart. That position is a narrow one. A club may value having a catcher available who can cover an injury or provide depth, while also preferring options who offer more at the plate or have a clearer path to regular playing time. The source doesn't quantify Rivero’s defense, so there's no basis here to rank it against other catchers; the practical point is that teams have continued to consider him because of that work. If you're working in this space, you know how quickly a reserve catcher’s role can hinge on availability and trust as much as on a season’s batting line. A specialist’s value can be real and still leave his roster spot vulnerable.

What the roster moves signal

Clearing two spots gives the Angels more room to manage the major league roster, while the outright assignments keep open the possibility of retaining both players in the organization. The club has effectively moved two players whose roles are uncertain out of the immediate roster picture. That can be a practical response to limited roster space: a team can preserve minor league depth where possible, then make other decisions about the major league group. The fact that neither player was claimed shows only that no club took him through waivers at this point. It doesn't prove that no team could want either player on a different arrangement or at a different time.

Both can elect free agency, which appears likely, and the source says they’ll probably seek minor league depth opportunities with new clubs. Such opportunities can give a player a chance to compete for a role while giving a team cover at a position where injuries and performance changes can quickly reshape its needs. For Peralta, the case rests partly on whether a club sees enough in his strikeout and walk rates to keep working through the home run problem. For Rivero, it rests on whether a team values his defensive contribution enough to carry a catcher whose offense has been limited. Different skill sets, similar uncertainty.

And yet, an outright assignment isn't a final judgment on either career. It marks a roster decision made with the players’ recent performance, available space and organizational needs in view. Here's the thing: the most useful clue isn't simply that both cleared waivers, but that their paths to another major league opportunity look different. Peralta needs his results to better reflect the more promising parts of his pitching profile. Rivero needs a club that sees enough value in his work behind the plate to make room for a reserve. The numbers are underwhelming in places, and neither profile guarantees a return to the majors. Still, both have a plausible route back through depth roles. (And this is the part most people overlook: depth only becomes visible when a club needs it.) For now, Salt Lake is the available landing spot; free agency would let each player look for a better fit.
