Major League Baseball's new replay system has had plenty of critics early in the season, but the league itself is very happy with the early returns.

"Before this system," Tony La Russa said, "all you could do as a manager, if a mistake was made [by the umpires], was go in, watch the replay [after the game] and say, 'Well, that call was blown, and hopefully it'll even out later on.' But now you have a chance to correct that blown call. And the ability to do that has already had a direct impact on what the final score was a number of times."

La Russa, who works in the league office, helped devise the replay system.

He estimated there have been "five or six games" already in which, basically, the right team won -- because of replay.
