Cardinals To Sign Ryne Stanek

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.

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 could 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.
