FORT MYERS, Fla. — Boston Red Sox pitcher Steven Wright will sit out the first 80 games of the season after testing positive for Human Growth Hormone, a second suspension for the knuckleballer who missed 15 games last year for baseball’s domestic violence policy.

Wright, 34, said in a statement issued through the Major League Baseball Players Association that he learned of the positive test during the offseason.

“Although I do not dispute the validity of the test, I was shocked as I have never intentionally ingested anything for performance-enhancing purposes,” the statement said. “I have fully cooperated with MLB and will continue to try and identify the source of the result.”
