Major League Baseball is making steps to expand instant replay to include trapped balls and line drives down the foul lines.

MLB Commissioner Bud Selig announced the plans on ESPN Radio Friday. 

"We're now going to add it on trapped balls in the outfield and as I call them bullets down the right and left field line," Selig said

Currently, replay is only used to determine home runs that are fair or foul and if they clear the ballpark's fences.

Selig did not say when the changes would be in place. The commissioner said he would continue to review the policy and that he was "very cautious" to make the changes. He expressed concern over the effect it could have on the pace of the game, but added that if umpires adhered to the rules already in place, the pace of the game would not be an issue.

Selig doesn't think that replay is getting in the way of the game, despite complaints from baseball purists.

"There are some people who believe that by going to the last two things, maybe I've gone too far and I don't think so," Selig said.
