What happened: Major League Baseball presented a new labor proposal offering to postpone the implementation of a salary cap until 2028. The MLB Players Association swiftly rejected the offer, stating the proposed economic overhaul continues to favor team owners over players.

Why it matters: The rejection leaves the two sides at an impasse with free agency underway and the Dec. 1 expiration date fast approaching. Without a ratified agreement or an extension before the deadline, baseball faces the prospect of an immediate owner-imposed lockout.

What to watch: Negotiators will work to resume discussions before the Dec. 1 deadline to prevent a winter freeze across the sport.
