The St. Louis Cardinals are getting a major boost to their roster as Jordan Walker officially begins a Triple-A rehab assignment, signaling his imminent return from an appendicitis scare that had sidelined him earlier this week. The news was first reported by STLToday’s Daniel Guerrero, who shared the following update on his X (formerly Twitter) account. “The #STLCards say Jordan Walker (appendicitis) is scheduled to begin a rehab assignment tonight with Class AAA Memphis.” Walker’s return could not come at a better time.
