Shaun Marcum done for season with thoracic outlet syndrome, according to reports
Shaun Marcum has been diagnosed with thoracic outlet syndrome and will undergo season-ending surgery Monday, according to multiple reports.
The Mayo Clinic describes TOS as such: "Thoracic outlet syndrome is a group of disorders that occur when the blood vessels or nerves in the thoracic outlet — the space between your collarbone and your first rib — become compressed."
The Mets activated 25-year-old pitcher Gonzalez Germen from Triple-A Las Vegas to fill his roster spot.
Marcum recorded only one win (1-10 record) and posted a 5.29 ERA with 60 strikeouts in his first season with the Mets. The 31-year-old missed about the first month of the season with right shoulder and neck issues.
TOS is the same injury that has plagued Jeremy Bonderman and Chris Carpenter. Bonderman went 1-3 with a 4.93 ERA in seven starts with the Seattle Mariners this season in his attempted comeback from the injury before recently being designated for assignment after back-to-back poor starts. Carpenter, the 2005 National League Cy Young winner, has yet to pitch this season for the St. Louis Cardinals and remains on the 60-day disabled list, but has begun throwing sessions.
