Major League Baseball Commissioner Bud Selig says the league and players' union have previously discussed the idea of a blanket policy regarding domestic violence during collective bargaining, yet so far baseball has opted to handle any issue on a case-by-case basis.

Selig, speaking Thursday at AT&T Park as part of his farewell tour before the Giants hosted Arizona, declined to address the NFL's situation surrounding the Ray Rice case and whether he thought there could be an impartial investigation.

Selig says he can't remember the last domestic violence case involving a baseball player. Talks about a policy could come up again in the next collective bargaining, but Selig leaves office Jan. 25 and Rob Manfred takes over.

"Yes, it has been discussed, because we're sensitive to all issues," he says.
