WASHINGTON -- Nationals outfielder Jayson Werth had arthroscopic surgery on his right shoulder, and the team says no structural abnormalities were found.
The operation was Friday at the Mayo Clinic.
Washington says Werth's rehabilitation is expected to take two to three months.
The 35-year-old was troubled by his right shoulder in early August, when he sat out a week. He wound up hitting .292 with 16 homers and 82 RBIs in the regular season for the NL East champions, then went 1 for 17 in the playoffs.
Werth has three seasons left on a $126 million, seven-year contract with Washington, which plans to have him switch from right field to left this season in a swap with Bryce Harper.
