It’s long been understood that the top priority for the Cardinals this offseason is adding to their starting rotation, with president of baseball operations John Mozeliak himself stating that the club intends to at three starting pitchers this winter. Even as the club’s focus seems to be on bolstering the rotation, however, The Athletic’s Katie Woo indicated today that the club plans to make additions to its relief corps as well, noting that the club plans to add “at least two high-leverage arms” who can join Ryan Helsley and Giovanny Gallegos in the club’s late-inning mix.
The news isn’t necessarily surprising. Cardinals relievers posted an uninspiring 4.47 ERA across their 579 2/3 innings covered in 2023, the third-worst figure in the NL above only the Nationals and Rockies. Only the Rangers’ relief corps had a higher ERA than the Cardinals this year when looking at teams that finished the season with a winning record, and just four (Texas, Cincinnati, Miami, and Arizona) even finished in the bottom half of the league. Given St. Louis has clearly indicated a desire to return to contention as soon as next season, shoring up the club’s bullpen mix figures to be a key component of that goal.
The Cardinals have already been connected to one upcoming relief free agent: NPB left-hander Yuki Matsui, who is expected to explore signing in the majors this offseason. While fellow southpaw JoJo Romero impressed in high leverage opportunities following the trade deadline, it would certainly reasonable if the Cardinals don’t want to anoint Romero as their bullpen’s top lefty after just 36 2/3 innings of work in the majors last year, no matter how brilliant he appeared to be in flashes.
Of course, Matsui isn’t the only left-handed relief option headed for free agency this offseason. The class is led by star closer Josh Hader, who authored a sensational platform season with the Padres in 2023. Hader struck out 36.8% of batters faced this season en route to a 1.28 ERA (321 ERA+), 2.69 FIP and 33 saves in 38 chances. Other potential high-leverage left-handers set to hit the market this offseason are veteran fireballer Aroldis Chapman and journeyman Matt Moore, who’s broken out over the past two seasons to become one of the top lefty relievers in the sport during his mid-thirties.
In terms of right-handed relief options, the market is a little thinner, headlined by former Cardinals closer Jordan Hicks. The Cardinals dealt Hicks to the Blue Jays at the trade deadline this year, though not before attempting to negotiate an extension with the 27-year-old hurler. Woo reports that the sides came close to an agreement on a three-year extension this summer before talks ultimately fell apart, prompting St. Louis to ship Hicks to Toronto.
Despite the sides parting back in July, Woo indicates that there’s reason to believe the sides could again look to negotiate a long-term deal this offseason, noting that “there’s no ruling out” a Cardinals reunion with either Hicks or left-handed starter Jordan Montgomery, who has impressed since joining the Rangers with a 2.79 ERA in 11 starts down the stretch and a 2.90 ERA in 31 innings of work during the club’s pennant-winning postseason run. If the Cardinals can’t get together with Hicks on a reunion, there are a few other right-handed relief options who could offer high leverage innings in 2023, including Braves righty Joe Jimenez as well as Reynaldo Lopez, who put up solid numbers while bouncing between the White Sox, Angels, and Guardians in 2023.
