The Athletics' bullpen was dealt a major blow on Thursday as reliever Trevor Rosenthal landed on the 60-day injured list. He's been dealing with a shoulder injury. Thoracic outlet surgery seems like the most likely outcome for the 30-year-old right-hander. Such a procedure would hold him out for at least three months. (Jessica Kleinschmidt on Twitter)
The timeline on Rosenthal has only gotten bleaker. He was initially dealing with minor aches and pains but pitched through the ailment. He then landed on the 10-day injured list without a timetable for return. Days later, he visited a specialist in Dallas who specializes in thoracic outlet surgery. Now, he's out for quite some time. It's tough news for the Athletics and Rosenthal, who agreed to a one-year, $11 million deal following an incredible bounce-back year in 2020.
