Base umpires will enforce the NCAA's new pace-of-play rules at the College World Series and other national tournament games in 2011.
Division I Baseball Committee chairman Tim Weiser said Thursday the committee decided to have a base umpire use a stopwatch to monitor time between pitches rather than require visible pitch clocks.
There is a 20-second limit between pitches when no runners are on base and a 90-second limit between innings during non-televised games.
After one warning, a ball or strike will be added to the count depending on whether the pitcher or batter causes a violation.
Weiser said no pitch clock would be used in the NCAA tournament because some conferences are planning to have a clock and some are not in the regular season.
