The use of video replay will be expanded at next month's College World Series to give umpires the ability to take a second look at a ball hit down an outfield line to determine if it's fair or foul.
Last year, instant replay was approved at the CWS for the first time and matched the major leagues' rules for use. The only plays eligible involved apparent home runs. The situation never arose.
In cases where runners are on base and a foul call is changed to fair after a review, the umpire crew chief will place runners where he thinks they would have ended up had the call been correct initially.
