Strasburg had a non-cancerous growth surgically removed from his back about one month ago, according to his agent Scott Boras, Jon Morosi of FOX Sports reports.

Recurring upper-back and neck issues hampered Strasburg on and off throughout the season, and it seems the growth may very well have been the cause. Apparently, the growth was "muscular" in origin, and the right-hander is said to be doing well a month removed from surgery. Strasburg managed to perform at an extraordinary level down the stretch despite the issue, posting a 1.90 ERA and 92:8 K:BB after the All-Star break.
