MLB commissioner Rob Manfred said a pitch clock will be used in spring training this year, according to ESPN's Jeff Passan. There is a possibility for the pitch clock to extend into the regular season, although Manfred would reportedly like to work with the player's union before making a decision.
A 20-second pitch clock was introduced across Double A and Triple A in 2015, with an automatic ball used as a penalty for pitchers who did not start their delivery before the clock hit zero. Manfred didn't specify what penalty will be used in spring training.
