Sam Dyson's season took a turn for the worst Wednesday.
The former Giants reliever underwent capsule repair surgery on his right throwing shoulder Tuesday, Twins manager Rocco Baldelli announced to reporters. The procedure could keep Dyson out all of next season.
Sam Dyson underwent capsule repair surgery in his right shoulder yesterday. He will not pitch again this season, and next season is also in jeopardy.
Rocco said the timeline for a return can be up to 12 months. Didn't know yet whether Dyson will pitch next year.— Do-Hyoung Park (@dohyoungpark) September 25, 2019
Dyson was traded from the Giants to the Twins at the July 31 MLB trade deadline, but was a much different pitcher in Minnesota than in San Francisco. He went 4-1 with a 2.47 ERA in 49 games as a Giant this year, but had a 7.15 ERA in 12 games for the Twins.
The Twins believe the Giants might have known Dyson was damaged goods at the deadline, too. The Star Tribune's La Velle E. Neal III reported Monday that the Twins have investigated whether the Giants were aware that Dyson had a sore shoulder when he was traded for three minor leaguers -- pitchers Kai-Wei Teng and Prelander Berroa, and outfielder Jaylin Davis.
Now that Dyson officially has had surgery, even more eyebrows will be raised. There were no red flags on Dyson's medicals from the Giants when the Twins acquired him, but according to the Tribune, Dyson told Minnesota he had been pitching with some shoulder discomfort since mid-July.
As Dyson might not be on a mound at all next season, don't expect this story to go away anytime soon.
