The Mariners and Cardinals are closing in on a deal to send infielder/outfielder Brendan Donovan to Seattle, per a report from Katie Woo and Chad Jennings of The Athletic. That report adds that a third team may be involved. Jeff Passan of ESPN reports that the Rays are the third team. Bob Nightengale of USA Today reports that Tampa is expected to get infielder Ben Williamson from the Mariners in the deal.
A Donovan trade has felt inevitable for quite a while. The Cardinals have been leaning harder into a rebuild this winter. They tried to kick off a reset last offseason but struggled to move their veteran players with no-trade clauses and ended up mostly standing pat. With president of baseball operations John Mozeliak ceding the reins to new president Chaim Bloom after the 2025 campaign, it became clear that the club would push harder to focus on the future.
Nolan Arenado, Sonny Gray and Willson Contreras all had no-trade clauses in their contracts and seemed reluctant to approve deals in the 2024-25 offseason. As last year was winding down, they all publicly expressed a greater openness to playing for new teams in 2026. That has now come to fruition for all three. Gray and Contreras were both traded to the Red Sox, while Arenado landed with the Diamondbacks.
Donovan’s situation was slightly different. Those other three guys were all veterans making eight-figure salaries. Moving them out of St. Louis was partially about slashing the payroll and also about opening up opportunities for younger players as part of the rebuild. Donovan, on the other hand, is still in his arbitration seasons. He will make a relatively modest $5.8MM in 2026 and would be due a raise in 2027.
It wouldn’t be necessary to trade Donovan for financial reasons at that price. But with the Cards expecting their rebuild to last a few years, it made sense to make Donovan available since he’s just two years away from free agency. An extension was another possibility but Donovan is now 29, so he’ll be going into his age-31 season in his first free agent year, and it’s unclear if the Cards will be competitive by then.
Donovan was a case where the front office wouldn’t have to worry about the contract and could focus on simply bringing back as much talent as possible. With his modest salary and inability to block trades, the Cards could scour the league to see what teams were willing to pay in terms of prospect capital. Since Donovan can play all over the diamond, with experience at all four infield positions and the outfield corners, almost any contender could fit him onto the roster.
It’s not just defensive versatility that Donovan brings to the table. In his four big league seasons, he has been remarkably consistent with a contact-based approach at the plate. His strikeout rate has been in the 12 to 15% range in each seasons of his career, during a time when the league average is usually around 22% or so. He has also drawn walks at a rate right around league par. He doesn’t have huge power but has hit at least 10 home runs in each of the past three seasons.
Put it all together and Donovan has a career .282/.361/.411 slash line. That translates to a 119 wRC+, indicating he has been 19% better than league average at the plate overall. Each of his four seasons has ended with a wRC+ between 115 and 127. A consistently above average hitter with an affordable salary who can capably play many different positions made Donovan a good fit for many teams and he reportedly received interest from about half the clubs in the league.
More to come.
