Rockies release catcher Andrew Knizner, making veteran backstop a free agent

The Colorado Rockies released catcher Andrew Knizner, according to his transactions listing. The move makes Knizner a free agent and eligible to sign with any club, a practical outcome for a position group that changes quickly during the summer.

Knizner, 31, had arrived in Seattle earlier in his career cycle, agreeing to a one-year, $1MM major-league deal with the Mariners in the offseason, before later landing in Colorado. In an era where backup catchers are often asked to do specific game-planning work and provide spot starts, a sudden release can quickly reshape a team’s depth planning.

MLB Trade Rumors reported the release in connection with Knizner’s current transactions status. The report also notes that his on-field performance had been strong enough to create speculation about whether he triggered an opt-out, though no formal explanation is stated in the transaction announcement itself. Until a club statement or another primary confirmation is available, the safest framing is that the Rockies have terminated the contract and Knizner is free to pursue his next role.

A release at this stage is not unusual in baseball’s day-to-day roster management, but it does carry a report about organizational priorities. Catching depth has to balance several realities at once, including the need for a reliable handler behind the plate, the value of game-calling consistency, and the development timeline for each catching prospect in the system.

For any team evaluating options, Knizner’s immediate availability is the headline. A free agent catcher can be added either as a backup who can start selectively or as a more durable depth piece, depending on what a club needs in its remaining schedule. The question will be how quickly contenders and playoff hopefuls, not just rebuilding clubs, move to fill a roster spot.

Knizner’s next destination will likely depend on more than just availability, including organizational catching philosophies, spring-training-style comfort with a starter’s staff, and each club’s internal assessment of his current skill set. The most important detail for tracking purposes will be whether he signs to a major-league roster immediately or lands with a new organization in a depth capacity.

The release also provides clarity on the Rockies’ current approach to their catcher mix. Whether the organization is leaning toward internal promotion, adding another veteran, or simply reallocating roster resources, fans should watch for a corresponding roster transaction from Colorado soon after the release becomes official in daily usage.
