The Cardinals are in agreement with free agent reliever Ryne Stanek, reports Robert Murray of FanSided. Chris Cotillo of MassLive first reported that St. Louis was pursuing the hard-throwing righty. The Cardinals will need to open a 40-man roster spot once the MVP Sports Group client completes a physical.
Stanek gets a change of scenery after an inconsistent year and a half with the Mets. New York acquired him from the Mariners at the 2024 trade deadline. While he allowed 11 runs in 16 1/3 regular season innings down the stretch, Stanek’s plus strikeout rate and strong postseason work led the Mets to bring him back on a $4.5MM free agent deal.
That didn’t pan out, as the 34-year-old had an up-and-down season. Stanek had strong run prevention marks in May and July but was knocked around in the other four months. He finished with a 5.30 earned run average across 56 innings. ERA estimators were only slightly more bullish as Stanek’s strikeout and walk rates each went in the wrong direction.
A 22.7% strikeout rate was narrowly the lowest of his nine-year career. Stanek had fanned nearly 28% of opposing hitters one season earlier. It’s crucial that he miss bats because command has never been a strong suit. Stanek has walked at least 10% of batters faced in all but one year, including a 12.5% mark last season.
The Cardinals are taking what should be a low-cost bet that he’ll strike out more batters in 2026. Stanek still has the stuff to do that. He averaged 98.5 MPH on his heater, a top 15 mark in MLB. He backs that up with a plus slider and mixes in a splitter and sweeper as his third and fourth offerings. Stanek still missed bats at a slightly above-average rate on a per pitch basis last year.
St. Louis doesn’t have a ton of experienced arms in the late innings. Southpaw JoJo Romero had been their only reliever with even two years of MLB service. There’s a decent chance he’s traded before Opening Day. The Cardinals were looking for a veteran arm who can pitch in the back half of the bullpen. Stanek fits best in middle relief but be in the high-leverage mix, perhaps even as a closer, on a rebuilding club. He’s a known commodity to president of baseball operations Chaim Bloom, who was in the Rays front office when Tampa Bay drafted him in the first round in 2013.
There’s also a geographic tie. Stanek was born in St. Louis and went to high school not far outside Missouri in Stilwell, Kansas. There’s a decent chance he’ll be traded midseason if he’s pitching well, but he’ll get a chance to play for his hometown club for at least a few months.
More to come.


O’Hearn, now 32, has been enjoying a late-career breakout over the past three seasons. He played parts of five seasons with the Royals from 2018 to 2022 with just a .219/.293/.390 line to show for it.
