BOSTON -- In typical Trot Nixon fashion, he never used an injury as an excuse for a decline in performance down the stretch of the season. But as it turns out, an ailing left knee might have been the culprit.
The Red Sox revealed Monday that Nixon underwent arthroscopic surgery on the knee last Friday in Boston. Dr. Thomas Gill, the medical director of the Red Sox, performed the operation.
The surgery is not expected to sideline Nixon at all, as he will resume his offseason conditioning program in two weeks.
According to a statement issued by a Red Sox spokesperson, the surgery was considered "routine and successful."
Nixon, limited to 48 games in 2004 due to back and leg woes, looked primed to have a strong comeback season in 2005. He hit .296 with nine homers and 42 RBIs prior to the All-Star break.
However, Nixon tailed off in the second half, hitting just .241 with four homers and 25 RBIs. After straining his left oblique muscle on July 26, he went on the disabled list and played a mere seven games in August.
He struggled mightily in September, hitting .233 with one homer and 10 RBIs. Nixon went 3-for-13 (.231) during the American League Division Series against the White Sox, which ended with Boston being swept in three straight games.
The primary right fielder of the Red Sox since 1999, Nixon is entering the final season of a three-year contract.
In 868 career games, all with the Red Sox, Nixon is a .279 hitter with 125 homers and 471 RBIs.
Red Sox left-hander David Wells is expected to undergo surgery on his right knee in the coming weeks, though there's been no official announcement on that yet. Wells was hindered by knee woes late in the season, but pitched through them, getting his final cortisone shot of the year on Sept. 21.
