who is the hardest throwing pitcher of all time
Steve Dalkowski Stephen Louis Dalkowski Jr. (born June 3, 1939[1]), nicknamed Dalko,[2] is an American retired left-handed pitcher. He is sometimes called the fastest pitcher in baseball history and had a fastball that probably exceeded 100 mph (160 km/h). Some experts believed it went as fast as 125 mph (201 km/h), others that his pitches traveled at 120 mph (190 km/h) or less.[3] As no radar gun or other device was available at games to measure the speed of his pitches precisely, the actual top speed of his pitches remains unknown. Regardless of its actual speed, his fastball earned him the nickname "White Lightning".[4] Such was his reputation that despite never reaching the major leagues, and finishing his minor league years in class-B ball, the 1966 Sporting News item about the end of his career was headlined "LIVING LEGEND RELEASED."[5]
Aroldis Chapman On July 11, 2014, Chapman broke the record, previously held by Bruce Sutter, for the most consecutive relief appearances with a strikeout, having struck out at least one batter in 40 consecutive appearances. Chapman's streak began on August 21, 2013,[2] and lasted 49 consecutive games over two seasons, with the 49th and final game being on August 13, 2014. He shares the record for the fastest recorded pitch speed in MLB history, at 105.1 miles per hour (169.1Â km/h),[3] as well as the Guinness World Record for fastest baseball pitch.[4]
