When the Twins acquired reliever Sam Dyson from the Giants ahead of the July 31 MLB trade deadline, they thought they were receiving one of the most reliable bullpens arms in baseball. So far, that hasn't been the case.
Far from it.
Dyson has a 7.15 ERA in 12 appearances for the Twins. He went 4-1 with a 2.47 ERA in 49 games out of the bullpen for the Giants before being shipped to Minnesota. But now, Dyson will meet with Dr. Neal El-Attrache on Monday about his aching shoulder and likely will need surgery.

SIGN UP HERE As the veteran reliever deals with health issues, the Twins are searching for answers. 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.
There were no red flags on Dyson's medicals from the Giants when obtained before the deadline. But the 31-year-old told the Twins he has been pitching with some discomfort since mid-July, according to the Tribune.
The Twins, however, have not been able to find any evidence the Giants had knowledge of a previous injury.
