Quick Looks: German & Peralta
• I got swamped last night during my chat on Peralta questions. I just didn’t know much about him so I went and watched his debut.
• It looks weird in that he is nearly falling down on every pitch and just averaging 90 mph on his fastball. It reminds me of high pitchers trying to reach 85-mph.
• Fastball: It sat at 87-95 mph with some nasty glove-side run. It could be considered a cutter at times. He used it like Mariano Rivera did by changing the spin. Partway through the game, MLB Gameday started labeling some of his pitches as cutters. It was not two separate pitches since there was no unique spin-velocity grouping
Note: Hopefully this week, I’m following up on this topic. I’m not sure what is a normal spin variation.

His pitches deviated by almost 1000 rpm.
The hitters seemed to have problems picking up it up. It’s tough to know his deception when watching him pitch from the rear camera angle. Here’s a look at some of his fastball variations.
Straight
With cut
Here’s a two-pitch back-to-back combo with one cutting away and another straight and high.
Cut
Up
• Curve/Slider. 77-81 mph with 12-6 movement. He had no feel for the pitch. It was all over the place.
• Scouting reports put him with an above average change-up but he never used it.
• He threw his fastball almost 90% of the time so hitters may start getting to it the second or third time through the lineup as they see the variations.
• He got rocked a few times with Charlie Blackmon just missing a grand slam foul.
Overall: He has no room for error or degradation. No extra velocity. Not even a serviceable second pitch, yet a third. His control won’t get better because he falls off the mound pitching. The max effort delivery means he’s at his max velocity.
I don’t know if I’d start him in his next start. The fastball works and that’s it. It’ll be interesting to see if he just didn’t have his breaking balls or they don’t exist. I’m trying to think of a comparable pitcher and Bartolo Colon is all I have. It’s an effective fastball but that’s it. How many starters get by with just their fastball? Hold and bench for now.
• I was hoping German didn’t throw at Yankees Stadium because the camera angle is offset but no luck. I decided to go ahead and watch his second start even though his pitch’s horizontal movement will be tough to see.
• Fastball: He’s got two, four-seam and sinker, and they’re weird. His sinker sits 93 to 97 mph while ith his 4-four-seamer is couple ticks slower at 92 to 96 mph. Normally, pitchers can throw their four-seamer faster. The other item is that his sinker has more spin than the 4-seamer. Again, this is backward as four-seamers normally have more spin which gives them their “rising” action.
Also, his fastball velocity has dropped in each of starts since moving from the bullpen.

This decline is common with the move as Jake Faria (’17) and Danny Duffy (’16) saw similar drops when they transitioned mid-season. His drop may be done has MLB.com reported that he sat at 94-mph as a minor league starter.
Sinker
4-seamer
• Curveball: Sat 80-83 mph with a 12-6. It seemed fast as it only varied 12 mph from his fastball. It’s at least an average MLB offering and he used it quite a bit in his last two innings.
• Change: A straight 86-87-mph change with some drop at lower velocities. It’s unique with its high 80’s velocity which is only 4 mph to 7 mph under his fastball. It seems like a pitch which will get crushed if timed right (Khris Davis launch one for a home run).
Overall: German is not someone I’m targeting to own. The skills seem OK. His fastballs are acceptable. His curve is great. And the change might be great when he’s throwing 97-mph out the bullpen. He’s not in the bullpen now and his fastball velocity is still dropping to a starter level. As his starter talent level becomes visible, owners will get a better idea of what to expect from him on a weekly bases. For now, I see him a streamable option whose value could change significantly over the next few starts.

Nice write up on German. Thanks.
Thanks
These were very quick but extremely informative blurbs on both pitchers. I would love to see more of these types of articles for anybody you’re willing to compile them for.
On the left are more under Quick Looks. I try to get to one a week.
“How many starters get by with just their fastball? ”
Tony Cingrani, for a few months
Yes he tried.
Hey, if I can milk Peralta for Tony Cingrani’s 2013, and then sell him to a doofus, that’d work for me!
He tipped his change-up to Khris Davis. I was watching with my nephew and I said look, he’s fiddling with his grip, going to a change-up grip it looks like. There was a runner on 2nd who likely saw what I saw.. Sure enough, wham. Not that it’s all that easy to homer even when you know a change-up is coming. That was a meatball.
Came for the scouting report, stayed to watch that broken bat in the German “4-seamer” vid over and over. The batter’s (Semien?) reaction is classic; all the more so since no one else seems to pause at all.
Do you think the fact that he was pitching in Colorado had anything to do with his lack of breaking balls thrown?
… and that he was, utterly, completely dominating. Interesting report. He both shows and demonstrates WHY he dominated, then tries to come up with reasons why it isn’t sustainable. He even SHOWS a nasty slider, then says he doesn’t have any other pitches lol
That sweeping cut to his fastball, away from righties, pretty much has the effect of a slider also. A wipeout one.
It will be cool tpo see people continue to be wrong about Peralta.
I always put in a .gif of his best of each pitch. There were only two near the plate. Image:

Notice the two curves barely on the image’s labeling in which he bounced way in front of the plate.
Yes I do notice them. You are just reporting what you see, but maybe it’s a strikeout pitch, meant to be out of the zone?
Also the numbers, visuals from other starts, and reports from other eyes are a bigger sample than this.
To me, its much more likely that he starts to mix in his other offerings than it is likely that people will just solve his fastball.
Im biased though. I LOVE prospects like this: Dominated AA… no body told me he could do that… has pretty well dominated AAA… nobody said that was likely… now this.
Being able to kill it with just your fastball should be seen as a remarkable feat, I think. Wow. Didnt Madison Bumgarner do that when he came up?
It could be. since he was in Colorado. I’d like to see another start as I stated in the article
This is awesome. Huge help! Sounds like you’d prefer to own Peralta over German right now?
Probably but I’m on a wait and see approach.
Jeff,
Drop M Fulmer for which of the following interim pitching options in a h2h league:
C Smith LAD, @NYM, WAS
Soroka CHC, @PHI, NYM
Flaherty @MIN, PHI, @PIT
Pivetta @BAL, @STL, TOR
Gibson MIL, DET, @KC
Kuhl SD, @CIN, CHC
F Peralta @MIN, NYM, STL
Thanks!
Flaherty …. Smith if you want K’s
Jeff, re: German — Eno seemed to think each of his pitches were above average offerings by movement, velocity, and spin rate (for the four seam and curve). Mentioned Scherzer as a potential comp for his four seam and Morton for the two seam, with Ivan Nova as one an overall comp … with, perhaps, more upside.
Curious your thoughts there.
My biggest issue is the FB drop and when it stops and how close it gets to his change. If the change is only 4 mph difference, it loses all effectiveness. My issue is that German’s current pitches, which may have included when he was in the bullpen, won’t be what he ends up with.
Looks like Peralta throws two fastballs: https://www.mlb.com/news/freddy-peralta-dominated-debut-with-1-pitch/c-276749356
