After hitting 102.7 mph in debut, Aroldis Chapman throws 103.9 mph in second appearance

Sep 2, 2010, 10:15 AM EDT

Aroldis Chapman made jaws drop in his MLB debut earlier this week by averaging 100.3 miles per hour on six fastballs and topping out at 102.7 mph, which tied for the highest velocity ever recorded during three seasons of’s Pitch-F/X system.
Or at least it was the highest.
Chapman made his second appearance last night, picking up his first career victory with a scoreless inning against the Brewers, and topped out at 103.9 mph. Seriously. He also threw a pitch at 103.8 mph and averaged 102.1 mph on seven fastballs, Yes, averaged 102.1 mph.
Chapman has thrown 13 fastballs so far at an average velocity of 101.3 miles per hour. To put that in some context, here are the highest average fastball velocities since 2007:
2010: Joel Zumaya – 99.3 mph
2009: Joel Zumaya – 99.3 mph
2008: Joel Zumaya – 97.5 mph
2007: Joel Zumaya – 97.5 mph
In other words, no one throws this hard. Chapman’s career is exactly two innings long at this point, yet he’s already thrown the three fastest pitches in Pitch-F/X history and his average velocity makes the previous king of hard-throwers, Joel Zumaya, look like Jamie Moyer.
Oh, and Chapman’s high-80s slider is nasty as hell too. He threw it four times last night and got three swinging strikes. I’m really not sure how someone would go about having success against a 101-mph fastball and wicked 87-mph slider. I guess the answer is “they wouldn’t.”
As the Reds pull further and further ahead of the Cardinals in the NL Central it looks more and more like Chapman could have some Francisco Rodriguez-in-2002 potential in the playoffs.

    Long suffering Reds fans deserve this. They’ve endured Queen Hindenburg and her foul little dog, years of Jim Bowden, ragtag teams, the fans sitting in front of them coming to terms with the bowl of Skyline Chilli they had eaten three hours ago, Dusty Baker, you name it. Other than the occasional Over the Rhine concert, they’ve had so little to smile about for a long, long time. As I number a lifelong and rabid Red Machine fan among my closest pals, it’s been hard to watch someone I love suffer so long, and through him, my bountiful sympathy has flowed to his comrades-in-wretchedness for years. This bullet throwing android is the perfect icing on the cake of this inspired season, and no doubt he is enjoying as much as I am watching the Cardinals implode. Clearly, rubbing glands with that raving buffoon and his quitmistress queen didn’t do much for Tony LaRussa and Prince Albert’s karma. I expect that by the end of the season, we’ll be hearing conflicting versions of how many games behind they finished.

    According to the radar gun in KC Neftali Feliz threw 103 a couple of times last night..

    I think they try to avoid things that happen in KC on this website, as it only allows a certain depression to set in. If only “long suffering Reds fans” had a taste of what it’s like to be a Royals fan.

    “makes … Joel Zumaya look like Jamie Moyer.”
    Only in America!

    Chapman, moving his glove to his left hand, ‘Oh, there’s something I ought to tell you. I’m not left-handed either.’

    Gun seemed at least 2 mph fast. Feliz has never gotten up that high, and the night before they had Ogando hit 100, and he’s never gotten that high either. Happened with a couple other pitcher in the series as well, I believe.
