Cardinals president of baseball operations John Mozeliak announced Sunday that starting pitcher Dakota Hudson will require Tommy John surgery. The news is a blow to the Cardinals rotation not only for the rest of this season, which Hudson was expected to miss anyway after the team placed him on the 45-day IL in recent days, but it’s also an unfortunate hit to the team’s 2021 roster.

Though the Cardinals’ description of Hudson’s injury was inconsistent on whether the problem was with the flexor tendon or the elbow in the days following the initial sign of a problem on September 18. Ultimately, after consultations with team doctors and renowned specialist Dr. James Andrews, “everybody concluded this was in his best interest,” Mozeliak said Sunday.

Cardinals team doctor George Paletta will perform the surgery Monday. The timing of the surgery puts Hudson’s status for the duration of 2021 in serious question.

Blue Jays closer Ken Giles, plagued by arm injuries throughout the season, is headed for Tommy John surgery that will quite likely wipe out the entirety of his 2021 campaign as well. Giles first announced the move via his wife’s Instagram account, and Toronto skipper Charlie Montoyo has confirmed as much, per ESPN’s Marly Rivera (Twitter link).

Giles’ arm problems date back to last season, when elbow issues prevented him from changing hands around the 2019 deadline in July. Giles looked like a prime candidate to move before then, as he was among the majors’ most dominant relievers. Toronto had to retain the hard-throwing right-hander as a result of his health woes, and the club could now lose him for nothing in the next couple months.

Verlander, the reigning AL Cy Young Award winner, announced via his Instagram account on Saturday that he has decided to undergo season-ending Tommy John surgery—the first time in his long and accomplished career that he has needed the procedure. Verlander, who has not pitched since Opening Day in July, said he consulted with several doctors before reaching his decision.

“I was hopeful that I would be able to return to competition in 2020,” wrote Verlander, “however, during my simulated game, unfortunately the injury worsened. Obviously, I’m extremely disappointed, but I will not let this slow down my aspirations for my career. I will approach this rehab the only way I know, attack and don’t look back.”

It didn’t look good when Roberto Osuna threw a pitch, pointed to the dugout and gestured for the trainer to come to the mound during Saturday’s game against the Angels.

On Tuesday, Astros manager Dusty Baker said the same thing about Osuna’s MRI.

The Astros closer reportedly was recommended to have season-ending Tommy John surgery, a source told Mark Berman, the sports director at Fox 26 KRIV-TV in Houston. Per Berman, Osuna will seek a second opinion before making a decision.
