Non-contending NL teams expected to place free agents on waivers before Saturday

What happened

Per MLB Trade Rumors, non-contending National League teams are expected to place impending free agents on waivers ahead of the Saturday deadline — a move that would shed the final month of those players' salaries while opening a path for them to land with playoff contenders. The outlet noted that the Reds have already placed players on waivers, a move that appears to be part of the broader late-August pattern the piece describes.

The logic behind the maneuver, as MLB Trade Rumors lays it out, is straightforward enough that it barely needs explaining — and yet baseball finds a way to make it feel like a revelation every August. A player who is an impending free agent on a team going nowhere is, in most cases, already a departing player. If the club has no intention of re-signing him or extending a qualifying offer, he will walk in the fall without returning any compensation. Placing him on waivers before the deadline accelerates that departure by roughly five weeks, relieves the non-contender of his remaining salary, and gives the player a chance to contribute somewhere that actually has a scoreboard worth watching in October.

Why it matters

The waiver wire in late August is one of baseball's quieter mechanisms — not as loud as the July 31 trade deadline, not as chaotic as the September roster expansion that kicks in two days later — but it carries real operational weight for both sides of the transaction. For the non-contending club, the financial relief is the primary driver. For the player, it is a chance to audition for a postseason roster rather than log out the string on a lost season. For the claiming team, it is a relatively low-cost way to add a known commodity at a moment when the standings are tightening.

MLB Trade Rumors traced the modern version of this practice back to the Angels in 2023, when Los Angeles used the wire aggressively to shed veteran salaries, dip beneath the luxury tax threshold, and improve their draft positioning ahead of losing Shohei Ohtani to free agency. The outlet noted that no other team has replicated that particular scale of activity, but that a handful of clubs have since used the mechanism to move one or two notable salaries in the same window.

The Saturday deadline is the operational hinge here. Under general league mechanics, a player must be in an organization by a specific roster deadline to be eligible for that club's postseason roster. The late-August waiver window exists precisely because it allows a player to clear, be claimed, and still meet that eligibility threshold — which is why the timing matters and why non-contenders who have already made their peace with the standings tend to act in this narrow window rather than waiting.

The numbers

The Chicago White Sox sit at 74-68 (.521), first in the AL Central, with a division magic number of 18. They enter Friday having dropped their last game, carrying a streak of L1 into a three-game road series at Target Field against the Minnesota Twins.

Luis Castillo is the reported probable for Friday's opener against Dean Kremer. Erick Fedde is lined up for Saturday against Bailey Ober. Jordan Hicks is the reported probable for Sunday's finale against Zebby Matthews.

Where the club stands

The White Sox are the AL Central leader at 74-68 (.521), and the waiver wire activity unfolding in the National League is worth monitoring from their vantage point. A contending club sitting atop a division with a magic number of 18 is precisely the kind of organization that might look at the waiver wire and find something useful — a veteran arm, a bat with postseason experience, a depth piece that costs nothing beyond the prorated salary of a player another team has already decided to let go.

Whether the White Sox engage with the claims that may emerge this week is not reported. What is reported is that the pool of available players is expected to grow before Saturday, and that contenders across both leagues will have the opportunity to claim them.

What we don't know yet

MLB Trade Rumors' framing is explicitly anticipatory — non-contending teams "are expected" to act before the deadline, not that they have done so beyond the Reds' reported moves. The specific players who may be placed on waivers, the teams most likely to claim them, and the salary figures involved are not detailed in the report. Whether any American League clubs will participate in the same way is also not addressed.

The report does not name which non-contenders are most likely to move players, nor does it specify how many transactions might follow the Reds' lead. The Saturday deadline is the known fixed point; everything else remains, for now, a matter of expectation rather than announcement.

What to watch

The Saturday deadline is the clearest marker. Between now and then, any club that has quietly decided a veteran impending free agent is not part of its future has a narrow window to act — and per MLB Trade Rumors, at least some of them are expected to use it.

For the White Sox, the more immediate focus is the series at Minnesota. At 74-68 (.521) with a magic number of 18 and a three-game road set against the Twins beginning Friday, the standings conversation is very much a live one. Luis Castillo, Erick Fedde, and Jordan Hicks are the reported probables across the weekend, and how that rotation performs against a division opponent will matter more to the AL Central race in the short term than anything happening on the waiver wire.

Still, the waiver deadline and the roster expansion that follows in September operate on overlapping timelines. The late-August wire is, in a sense, the last quiet moment before the roster rules shift and the playoff picture sharpens. Non-contenders shedding salary, contenders adding depth, and players getting a second act — it is one of the more human corners of a transaction calendar that can otherwise feel purely mechanical. Watch for clubs to move before Saturday, and watch for claiming teams to emerge shortly after.
