St. Louis Cardinals designate pitcher Jared Shuster for assignment and eye promotion of prospect Quinn Mathews

The St. Louis Cardinals have designated right‑hander Jared Shuster for assignment after his latest appearance resulted in seven earned runs on just one out. Shuster, who has been shuttled between the major‑league roster and Triple‑A this season, cleared waivers previously and is expected to be reassigned to the Memphis Redbirds.

Meanwhile, the club is considering a call‑up for top prospect Quinn Mathews. The 20‑year‑old right‑hander has posted a 3.53 ERA in 17 Triple‑A starts, with a recent 1.87 ERA over his last eight outings. Cardinals analysts suggest that Mathews could replace struggling starter Matthew Liberatore, who holds a 5.34 ERA, either by joining the rotation or by moving Liberatore to a bullpen role.
