Michael Kopech, a prospect who was traded from the Chicago White Sox to the Boston Red Sox in the trade for Chris Sale, threw a 100-MPH fastball a week before his 19th birthday. Last year, in the Class-A level minors, Kopech hit 105 MPH.
Kopech's personal trainer, Bobby Stroupe, was recently caught telling Bleacher Report he thinks Kopech will be able to reach 107 MPH one day. If he does this during his stint in the majors, as long as he gets there, he could set the MLB record for fastest pitch recorded.
There have been quite a number of hard throwers when it comes to the MLB, but who has the fastest pitch? Well, here's the five fastest ever recorded.
First some clarification: Trying to find these official pitches are hard enough. These are the fastest pitches officially recorded without controversy. Aroldis Chapman supposedly hit 106 at one time, but official sites state the pitch was 105 MPH. And rumors state Bob Feller hit 107 MPH and Nolan Ryan hit 108 MPH, but nothing official has been recorded for those pitches.
5. Henry Alberto Rodriguez
While he isn't officially retired, Rodriguez has not seen the field during the regular season since 2014. He could definitely throw hard, but he had a lot of control issues, leading the National League in wild pitches in 2011, as well as having a high walks per nine innings rate.
His fastball tended to land somewhere between 96 and 100 MPH, but one relief appearance in 2010 saw him hit 103.2 MPH, according to the pitch-tracking system PitchF/x.
4. Andrew Cashner
In 2012, Cashner was dealt from the Chicago Cubs to the San Diego Padres in a move for a first baseman named Anthony Rizzo. While Rizzo went on to become a star player on last year's World Series team, the Padres set out to make Cashner a starter.
Unfortunately for Cashner, between the end of the 2012 and early 2013, he dealt with a few injuries. But before Cashner left his reliever role, he was recorded to have thrown a 103.3 MPH fastball during a 2013 preseason game.
3. Neftali Feliz
Before injuries went on to hamper him, Feliz was a primary reliever (specifically closer) for the Texas Rangers, especially during their back-to-back American League Championsihp seasons in 2010 and 2011. It was during one 2010 appearance where Feliz was recorded to have thrown a 103.4 MPH pitch.
2. Joel Zumaya
You may have noticed I never said anything about a record yet. Well, that's because in 2006, Joel Zumaya set this. Now, Zumaya would end up getting knocked around by injuries after that rookie year, with his last MLB appearance coming in 2010.
But during the 2006 season, he was a fan favorite along with Justin Verlander on that ALCS-winning Detroit Tigers team. In one relief appearance that season, he clocked in at 104.8 MPH.
It was the MLB and world record...at the time.
1. Aroldis Chapman
Sure, maybe his supposed 106-MPH pitch didn't count, but Chapman still officially holds the MLB record, and the Guinness World Record for that matter, of fastest pitch thrown. On Sept. 24, 2010, Chapman threw a pitch that clocked in at 105 MPH and sent the Cincinnati faithful into a frenzy.
Chapman is such a talented pitcher, by the way, that he ended up tying his own record. Now pitching for the New York Yankees, he threw another 105.1 MPH pitch during a mid-July 2016 game with the Baltimore Orioles.
Personally speaking, I'm glad he's a Yankee.
