The San Diego Padres have taken a very recognizable approach to roster construction this offseason. They are not attempting to win the winter on headline signings or long term commitments. They are attempting to win it by identifying players whose market value has collapsed and asking a simple question.
Was the decline real, or was it temporary?
Over the past several days San Diego has reportedly added Germán Márquez, Griffin Canning, and Nick Castellanos on low cost deals. None of these players are unknown quantities. Each has produced at a clearly above average major league level within the last several seasons. At the same time, each arrives in San Diego following either significant injury, performance collapse, or both. That combination tends to create the type of inefficiency smaller market contenders attempt to exploit.
The Márquez signing is the clearest example of this logic. At his peak in Colorado, Márquez was a dependable mid-rotation arm capable of absorbing innings at a rate most clubs struggle to replace internally. In 2021 he threw 196 innings with a 3.77 ERA while pitching half his games at Coors Field. That is a profile teams typically pay for. What they do not typically pay for is the post-Tommy John version of that same pitcher who returned to post a 6.70 ERA in his most recent full season.
The question facing San Diego’s front office is whether that performance represents a new baseline or a transitional phase associated with post-surgical recovery. Pitchers frequently require a full competitive season before command and velocity stabilize following ligament reconstruction. If Márquez is able to recover even part of his prior form in a less hostile run environment than Colorado, the Padres have effectively acquired a mid-rotation starter at a fraction of the open market rate.
Griffin Canning presents a similar case with a different mechanism of risk. Prior to injury in 2025, Canning carried a 3.77 ERA through 16 starts and demonstrated meaningful improvement in both strikeout rate and hard contact suppression. His season ended abruptly with a ruptured Achilles tendon, an injury that introduces substantial uncertainty into any projection for availability and durability the following year. Pitchers do return successfully from this type of lower body injury, but the rehabilitation timeline often affects early season workload and mechanics.
From a roster construction standpoint, this creates an opportunity. Players returning from major injury tend to sign shorter deals with lower guarantees in order to reestablish value. If Canning returns to his pre-injury performance level by midseason, San Diego gains a controllable starting option without having committed to a multi-year obligation during the recovery period.
Nick Castellanos is the least medically complex addition and perhaps the most financially efficient. Philadelphia released him despite remaining contractual obligations, meaning the Padres are responsible only for the league minimum salary while the Phillies cover the majority of his deal. Castellanos’ offensive output has fluctuated considerably over the past several seasons, but his underlying contact metrics have not deteriorated to the extent typically associated with permanent decline.
In practical terms, San Diego has acquired a player who has produced multiple 25 home run seasons at the cost of a replacement level bench bat. Even moderate regression toward his career norms would generate surplus offensive value relative to expenditure.
Taken individually, each of these acquisitions carries obvious downside risk. Márquez may not regain command following surgery. Canning’s recovery timeline may extend into the second half. Castellanos may continue the production trend that led to his release. However, roster construction decisions rarely operate in isolation. Evaluated as a group, the Padres appear to be employing a portfolio strategy built around variance.
Rather than committing significant payroll to a single high certainty asset, they have distributed minimal financial exposure across multiple rebound candidates. The probability that all three fail to return to form exists. The probability that at least one produces above contract value is meaningfully higher.
In an environment where mid-rotation starters routinely command eight figure annual salaries and league average corner outfield production is increasingly expensive, this approach attempts to capture value from players whose short term indicators have depressed their market price.
San Diego is not attempting to eliminate risk this winter. They are attempting to buy it cheaply and hope that regression, health normalization, or environmental change converts at least one of these outcomes into a competitive advantage by midseason.
