It turns out that the home of the Arizona Diamondbacks is a stadium that has the Trackman system in it. That means that we’ve got information from spring training game yesterday to look at, particularly from the pitchers. Here’s the list of guys we will be looking at today who pitched for the Cincinnati Reds on Monday: RHP Tyler Mahle, RHP, Evan Mitchell, LHP, Wandy Peralta and LHP Cody Reed.

Those were the minor league arms that pitched in the game. Scott Feldman and Blake Wood also saw action in the game, but we aren’t as concerned about the information on those guys. One of these guys did something that really jumped off of the page. Tyler Mahle didn’t had the best outing of the day. He is, however, the guy that stood out the most to me on the day.


Tyler Mahle | RHP

According to the data he averaged 94.8 MPH with his fastball. That’s significantly harder than I, or anyone I spoke to about him, had him throwing last season. The data had him topping out at 97.2 MPH, which also would be the hardest I’ve seen anyone mention him throwing. In 2015 I did have a report of him throwing 96 at times – and to be perfectly fair, the Trackman system does measure velocity slightly closer to release than a radar gun does – so a 96 on a radar gun could be a 97 via a Trackman system. Two other pitches were also in that range, with a 96.8 and a 96.9 MPH pitch in the bunch.

It appears that Mahle was also throwing something that resembles a cutter in the 87-89 MPH range. There was also one change up at 84 MPH.

Trackman isn’t perfect. It’s not always accurate or calibrated correctly. It’s generally pretty reliable, but not perfect. So I reached out to a guy who works with the Trackman and Pitch F/X data for a living. I asked if the system in Scottsdale is known to be “off”.  I was told that it can be a bit “noisy” at times. When a guy who’s never thrown this hard before comes out, even if it’s just in one inning, and is throwing this hard on February 27th, it’s certainly questionable. So I reached out to the Reds to see if I could confirm whether or not they also saw this from Tyler Mahle in the past, or if they got the same reading(s) today. It was confirmed for me that the information was also what the organization got from the game.

If you’re going to have a guy like Tyler Mahle who can pound the strikezone and can throw 97 MPH…. that’s something to really start getting excited about.

Evan Mitchell | RHP

We have past data to go on with Evan Mitchell as he pitched in the Arizona Fall League last year where several parks have one of the two pitch tracking systems in place. While there he averaged 96 MPH with his fastball. On Monday afternoon he averaged 93.4 – which, given where things are in spring training, shouldn’t be surprising that it’s down a bit from there. It’s February after all. In the game he topped out at 95.2 MPH. The right hander mixed in a slider between 85-87 MPH.

Wandy Peralta | LHP

Peralta pitched in the big leagues last season with the Reds, so there’s data from the past on him. In limited action last year in a late season call up he averaged 96.3 MPH. He topped out at 98.4 MPH. On Monday afternoon he averaged 96 MPH and topped out at 97.7 MPH. He also mixed in two sliders and what looks like a change up, all between 87-89 MPH.

Cody Reed | LHP

Reed pitched in the big leagues for quite a while in 2016 with the Reds, so there’s plenty of data available on him. What’s interesting is that if we look month-by-month for Reed last year, it was March in which he had his highest fastball velocity (March 21st, 94.8 MPH for the average). He averaged 94.2 MPH on Monday with the pitch, topping out at 96.5 MPH. It looks like he only used two change ups and a few sliders, all between 87-89 MPH.

    Mahle is just 22, and he has a solid 6’4″ frame. It’s not out of the realm of possibility that this is just his body maturing and velocity he touched in the past becomes a little more common. He was listed as 6’4″ and 200 lbs last year, I wonder if he is a little heavier now, and what kind of strength and conditioning program he has been on over the past couple of years. A couple of the national prospect rankers were high on Mahle, this could be a breakout year for him. He’s in AA at age 22 with a career walk rate of 1.8 bb/9 and now he is throwing mid to upper 90’s. Can’t wait for the season to start, and to see if the velo holds.

    The Reds coaches have been singing Peralta’s praises. If he had a good spring, I think he’s a virtual lock to make the team. I have to imagine they want more than 1 LHRP of it’s at all close.

      Mahle doesn’t get hit or walk batters, great combination for a starting pitcher that could force the Reds to make other potential starters relievers. The kid has done it at every level and that makes a big difference.

    I was surprised on gameday they had him throwing a bunch of 95 4seam fastballs. But they also had a bunch at 88-89 they called fastballs was wondering if it was something different.

    I have hopes with Mahle because of his control

      The pitches at 88-89 were likely mislabled. Based on the spin and movement, they *seem* like they were probably cutters.

    With Bailey, Desclafani and Finnegan set in the rotation. I believe Reds need and can feasibly get a minimum of 1 SP from next two waves. These are my 2 waves in order of most likely to become a Reds SP. Obviously, if more than 1 works out and allows Reds to trade one of current 3, that would be ideal.

    2017 Wave: Reed, Garrett, Stephenson, Davis
    2018 Wave: Mahle, Gutierrez, Castillo, Romano, Stephens, Mella
    2019-20 Wave: Santillan, Kahaloa, Lopez, Moss

    Imagine if 2/3 of Reed, Garrett and Stephenson figure it out. Add in Bailey and Finnegan. Move Desclafani at trade deadline or in off-season for a haul.
