Baseball Commissioner Bud Selig says he did the right thing in suspending Alex Rodriguez for more than one season.

Selig says he "can't control what people are saying." He adds that he has "a job to do, and that's protecting the integrity of the game and enforcing it."

The commissioner says he's very comfortable with what his staff has done, calling it the toughest drug-testing program in American sports. But to have an effective program, he says it has to be enforced.

Selig made his comments Thursday in Cooperstown while announcing a major expansion of video replay for next season.

Rodriguez was among 13 players suspended Aug. 5. The New York Yankees slugger received a 211-game ban, by far the longest, and has appealed it.
