According to the Chicago Tribune, Chapman's 103 mph pitch is 2 mph shy of his MLB record, 105.1 mph, which allows hitters 0.392 seconds to react.
Chapman struck out the side to earn the save and give the Cubs a ninth straight win. With Chapman closing games the Cubs have regained their early-season form and marched to an MLB-best record of 71-41.
