The Cardinals designated lefty Luis Peralta for assignment Friday, the team announced. His 40-man roster spot goes to fellow southpaw Jared Shuster, whose contract has been selected from Triple-A Memphis. The Cards opened an active roster spot by optioning righty Hunter Dobbins to Triple-A following yesterday’s season debut.
St. Louis only claimed Peralta off waivers out of the Rockies organization three days ago. He’s yet to even pitch in a game in their system and will now be in limbo for up to a week as he awaits the outcome of this morning’s DFA. The Cardinals will have five days to either trade Peralta or place him back on outright waivers. Since outright waivers are a 48-hour process, it could take up to seven days for a resolution.
The 25-year-old Peralta has pitched in parts of two big league seasons, both with the Rockies. He’s logged 31 1/3 MLB frames and been charged with 21 earned runs (6.03 ERA) on 33 hits, 23 walks and four hit batters. He’s fanned 30 of his 150 opponents. Peralta is effectively a two-pitch reliever, working off a four-seamer that averages 94.7 mph and a curveball that sits 81.7 mph. He mixes in an extremely occasional mid-80s changeup; only two percent of his MLB pitches have been changeups.
Peralta had a huge 2024 season in the minors, logging a pristine 0.94 ERA with a 40.1% strikeout rate and 11.2% walk rate in 47 2/3 innings across three minor league levels. He’s been hit hard and missed time with a hip injury over the two subsequent seasons. If the Cardinals can succeed in passing him through waivers, he’ll have to head back to Triple-A Memphis, as he lacks the prior outright or three years of MLB service time needed to reject an outright assignment to the minors. He’s already been claimed once and has a pair of minor league options remaining, however, so it’s possible another club will scoop him up.
Shuster has already had one stint with the Cards this season. The 27-year-old pitched 3 2/3 innings and allowed two runs before being designated for assignment, clearing waivers and accepting an outright assignment to Memphis.
A former first-round pick by the Braves, Shuster has pitched in parts of four major league seasons without much success. He owns a lifetime 5.26 ERA in 145 1/3 innings and has posted strikeout and walk rates that are both worse than league average. He’s been tagged for nine earned runs in 9 2/3 Triple-A frames this season.
It could very well be another short stay on the roster for Shuster. The Cardinals needed a fresh arm in the bullpen after Dobbins was chased in the fifth inning yesterday. They needed five relievers to get through the rest of the game. All five threw at least 15 pitches. Ryne Stanek and JoJo Romero have both pitched on consecutive days and combined for 37 and 38 pitches, respectively. The Cards would probably prefer to stay away from either, if possible.
