It took most of the baseball season, but doctors reached an opinion on what was wrong with Tyson Ross’s shoulder:

After starting opening day and then missing the rest of 2016, the Padres right-hander is scheduled to undergo surgery in St. Louis to deal with symptoms of thoracic outlet syndrome, manager Andy Green said.

…

Ross spent a number of weeks traveling around the country to obtain medical opinions from different doctors. After conferencing with multiple specialists and team physicians, Ross and the Padres determined surgery was the best course of action.

Should the procedure work, it would fix what became a mysterious, season-long problem. In July, Ross was nearing a rehab assignment when he suffered a fluke setback, spraining an ankle in a hotel room. He worked his way back to one rehab game with High Single-A Lake Elsinore in late August, but he was waylaid by further shoulder discomfort.

I hope it works. He should be ready for spring training.

Correction: Had the wrong Ross brother.
