Here in the SEC conference this season, we are testing a pitch clock (similar to a shot clock in Basketball) this season. With no runners on, the pitcher has 20 seconds to step on the mound and throw the ball. If he steps off, the clock stops until he steps back on and then resumes. Failure to throw the pitch will be called a BALL. When the batter calls time, the clock resets. The clock also runs for 90 seconds between innings for warm-ups.
