Earlier today, it was announced that Pittsburgh Pirates right handed starting pitcher Chris Archer will undergo thoracic outlet surgery, and will miss the entirety of the 2020 season if there is a season. The Pirates themselves released the news on twitter.
This kind of surgery does not have a good track record of pitchers finding their way back to being successful major league pitchers. Although there are a few success stories such as Chris Carpenter and Chris Young, they are outweighed by the failures like Tyler Thronburg, Matt Harvey, Tyson Ross, and Carter Capps.
