MLB Rumors: The Minnesota Twins acquired Sam Dyson from the San Francisco Giants at the trade deadline, thinking that the former Texas Ranger closer would fortify their bullpen for the playoffs. Dyson almost immediately landed on the injured list, however, and is now reportedly headed for shoulder surgery that will keep him out until mid-2020.
Per the LaVelle Neal story linked above, “[t]here were no red flags on” Dyson’s medical records that were provided to the Twins before the deal, but Dyson said when he arrived in Minnesota that he had been “pitching with some discomfort” since the middle of July. That said, unless the Twins can show that the Giants knew about the situation and didn’t disclose it, or kept two sets of medical books — like the San Diego Padres were doing in 2016 — Minnesota doesn’t appear to have any remedy.
Dyson has always been seen as an injury risk, which is a major reason why the Toronto Blue Jays waived him in 2013, and why the Marlins were willing to deal him to Texas for a pair of fringe prospects in Cody Ege and Tomas Telis.
Dyson had a terrific run in the bullpen for the Rangers from the time they acquired him in July, 2015, through the end of the 2016 season, but the wheels came off in 2017, with Texas ultimately trading him to San Francisco for a player to be named later (who became outfielder Hunter Cole). Dyson got his career back on track for the Giants, though we will have to see how the 31 year old bounces back after shoulder surgery.
