SEATTLE -- Seattle Mariners left-hander Marco Gonzales will undergo nerve surgery and will miss the rest of the season.
Gonzales will have surgery Aug. 22 to decompress the anterior interosseous nerve in his left forearm. The 31-year-old hopes to recover by spring training.
"This comes after a lengthy process of trying to find answers," Gonzales said Sunday. "This gives me the best chance to move forward and get past this so it doesn't happen any further."
Gonzales was 4-1 with a 5.22 ERA in 10 starts. He hasn't pitched since May 28, when he felt discomfort in the forearm after throwing 5 2/3 innings against Pittsburgh.
