Rays right-hander Alex Cobb was sent to the hospital after his most recent outing due to an odd numbness in his throwing hand.
Doctors found nothing wrong initially, but further tests this week revealed “blockage” near the first rib on the right side of his body.
According to Marc Topkin of the St. Petersburg Times, Cobb will have it all fixed through a season-ending surgical procedure Friday at the Baylor University Medical Center in Dallas, Texas.
Cobb, 23, posted a 3.42 ERA and 37/21 K/BB ratio over his first 52 2/3 major league innings this season. He had a 1.87 ERA and a 70/16 K/BB ratio in 67 1/3 frames at Triple-A Durham before his promotion.
The Rays are fully expecting Cobb to be ready for the start of spring training next February.
