	During the 2014 season, the Atlantic League of Professional Baseball instituted its own changes. These included using a 12-second pitch clock, reducing timeouts and warm-up pitches, and making intentional walks automatic by signalling the umpire, rather than throwing four intentional balls. The Arizona Fall League began using a pitch clock in 2014 and the Double-A and Triple-A levels of Minor League Baseball followed suit in 2015. Those levels saw a 12-minute reduction in game times.
