With playoff roster eligibility looming, waiver candidates remain in play for MLB contenders

Next Monday, Aug. 31 at 11:59 p.m. ET, is the postseason roster eligibility deadline in Major League Baseball, a date that can shape roster decisions even for players who are not on a team’s active postseason list at the time. In general terms, the rule is straightforward: a player does not have to be on the MLB roster on the deadline, but he must be in the organization to be eligible for the postseason. CBS Sports highlighted several waiver candidates who could become part of a contender’s October picture before that cutoff, including two notable names who already reached the waiver wire earlier this week.

According to the CBS Sports report, Eugenio Suárez was placed on waivers earlier this week and went unclaimed. The same outcome applied to TJ Friedl, who was also reportedly placed on waivers and did not get claimed. When a player clears waivers, it typically means the original club can keep him in its organization without an immediate change of teams, though it does not eliminate the possibility of an eventual shift if later roster moves place him back into the waiver pipeline.

For contenders evaluating roster construction, the key is that Aug. 31 is not just a date for who is on the 40-man or who has already been penciled into a postseason role. Instead, it becomes a practical checkpoint for organizational control. Teams can weigh whether a player who clears waivers but remains within their system could still be used in October, particularly when those clubs need specific bench bats, defensive flexibility, or matchup-oriented options.

The waiver system itself is often misunderstood as a routine procedural step, but it has strategic consequences as the postseason approaches. A player who is already eligible to be traded can still be complicated to acquire directly at the deadline window, while waivers offer another route for clubs that want to add depth while avoiding certain constraints that can come with other forms of roster movement. That is why reports in late August frequently emphasize “what might be available” rather than only what has already been settled.

CBS Sports’ broader framing identifies multiple players who may be in the same decision space as Suárez and Friedl, meaning they could become either available for pickup via waivers or remain with their current organizations after clearing. Even without a claim, the process still informs planning: it clarifies which players are removable from a roster balance and which teams are willing to spend waiver claims to secure immediate organizational depth.

What to watch next is whether additional waiver candidates emerge in the days before Aug. 31, and whether any claims materialize that directly change a team’s bench and late-inning options for October. Just as importantly, teams will continue to monitor internal roster health and how far they are from the roster flexibility they want going into the postseason eligibility checkpoint.

In the short term, the clear waiver results for Suárez and Friedl suggest that at least one part of the market for their particular profiles was not strong enough for another club to make a waiver claim. In the longer term, though, October eligibility rules make the final week in August decisive for organizations that want to ensure their October roster includes players they can legally use once the postseason starts.
