Rosenthal, who officially landed on the 60-day IL today, underwent the surgery in Dallas under the expertise of Dr. Gregory Pearl. The right-hander will recover for roughly eight weeks before returning to Texas for a follow-up visit. Rosenthal agreed to a one-year, $11 million deal following an incredible bounce-back year in 2020.

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.

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.

A's manager Bob Melvin told reporters on Wednesday that "surgery is on the table" for Trevor Rosenthal because of his shoulder injury.

It was reported on Tuesday that Rosenthal had seen a doctor who specializes in surgery for thoracic outlet syndrome, so Melvin's comments aren't exactly out of left field. Unfortunately, if Rosenthal does need surgery, it will almost certainly sideline him for the season and, as we've seen with pitchers like Matt Harvey, could have a significant impact on his career. Reading the tea leaves, it seems increasingly unlikely that Rosenthal will pitch this year, and his fantasy managers should try to secure either Jake Diekman or Sergio Romo to accrue at least some saves from Oakland.

Rosenthal was placed on the injured list after dealing with shoulder fatigue towards the end of spring training. It sounds like his exact timetable is still uncertain. Oakland manager Bob Melvin told reporters about a week ago that Jake Diekman would be the top option when it comes to save opportunities in the ninth inning while Rosenthal is sidelined.

The Oakland Athletics placed closer Trevor Rosenthal on the 10-day injured list with shoulder fatigue on Thursday afternoon, and manager Bob Melvin says the closer was having trouble bouncing back after outings and currently does not have a timetable for a return.

With Rosenthal out for what sounds like at least a couple of weeks, left-hander Jake Diekman is expected to see the majority of the save opportunities. Monitor Rosenthal's status for updates in the coming days.
