Who is the Hardest Throwing Pitcher in the MLB?

Aroldis Chapman is the hardest throwing pitcher in the major leagues today. He is currently on the New York Yankees where he comes in to closeout games that are really close in score, or to just get a few batters in. He throws the hardest out of any player and pitcher with a pitch that clocked in at 105 mph. His fastball being his hardest pitch makes his off speed pitches around 85 mph which is still really good since off speed pitches are a lot slower than the fastball. He is a Cuban-born American professional baseball pitcher where he started off in the Cuban National Series Holguin. During his career he played for other teams including the Cincinnati Reds, and the Chicago Cubs. His best year being last year in 2019 where he had just a 2.21 earned run average. Things are looking up for him with a 5 year/86 million dollar contract through 2021 and free agency in 2022 where someone will definitely pick him up and give him a great contract. He exceed his rookie limits in 2011 the year after his debut in 2010. Overall Chapman has had a great career only going between 3 different teams having great stats and making plenty of money through the years. With new pitchers coming to the MLB every year and Aroldis Chapman being an older player in his thirties someone in the next couple years will definitely be able to beat his stats with overall speed with his fastball, and also overall speed in his off speed pitches.
