St. Louis Cardinals announcement

Brian Walton’s take

Fernandez, who was sent down to Triple-A most recently with Sunday’s activation of Kwang-Hyun Kim, could be recalled inside the normal 10-day window because he is replacing an injured player. Flaherty exited Tuesday’s home loss to Detroit after yielding four runs in two innings.

Speaking of Kim, the lefty is a candidate to take Flaherty’s next turn in the rotation, which will be in Sunday’s Game 4 finale in Pittsburgh. 40-man roster starters Johan Oviedo, Jake Woodford and Angel Rondon wait in Memphis for another shot with St. Louis.

The Cardinals have not yet shared full details on the extent of Flaherty’s shoulder injury but acknowledge it could be season-ending. With the team’s playoff hopes getting thinner by the day, a longer-term view may be taken.

Due to an oblique injury that is reportedly unrelated to the current problem, Flaherty previously missed 60 games this season (from June 1 to August 13), spending time on both the 10-day and 60-day injured lists.

If the Cardinals need another 40-man spot between now and season’s end and Flaherty is indeed done for the year, he could be returned to the 60-day IL.

That could open the door for a non-roster replacement candidate, top pitching prospect Matthew Liberatore. The 21-year-old lefty, who also started Tuesday evening for the Triple-A Redbirds, has a sharp 2.84 ERA in four August starts. Liberatore is The Cardinal Nation’s no. 2-ranked prospect.

Other Wednesday Cardinals system news

  • Peoria 1B Brady Whalen begins rehab assignment with the FCL Cardinals
  • IF Ramon Mendoza transferred from Palm Beach to the Florida Complex League
  • RHP Gustavo Rodríguez reinstated from Palm Beach’s 7-day IL and transferred to the Complex League


The 23-year-old has been out for exactly one month, having been placed on Peoria’s injured list on July 25. Whalen is slashing .255/.318/.432/.750 in his second year with the Chiefs. He was also a member of the club in 2019 when it was part of the Low-A qualification.

Brady Whalen

While out, Whalen has been replaced in the Chiefs lineup at first base with Todd Lott, called up from Low-A Palm Beach.


When I was with Palm Beach recently, it appeared to me that Mendoza seemed overmatched at the plate against Low-A pitching.

Ramon Mendoza

Only 20 years of age, Mendoza returns to the level he had been assigned until his July 27 promotion upward to Palm Beach. With the Beach Birds, the right-handed hitter went 2-for-26 with four walks for a slash line of .077/.226/.115/.341.


The former starter in Palm Beach’s rotation is the second Beach Birds player backed down a level on Wednesday. Again, the performance tells the story.

Gustavo J. Rodriguez

Rodriguez, also 20, logged a 7.36 ERA in 16 appearances, including 10 starts with Palm Beach. The right-hander fanned 41 in 40 1/3 innings, but allowed far too much traffic on the bases – 51 hits and 27 walks for a bloated 1.93 WHIP.
