What To Watch For In Spring Training: Starting Pitchers

Which pitchers should we be monitoring in Spring Training?

We’re over a week into Spring Training and as we do our very best to tell ourselves that March games should have little-to-no effect on our drafting strategies, we have to acknowledge that there are always exceptions.

Pitchers can illuminate plenty in their early starts, let it be an increase in velocity, a firm grasp of a rotation spot, new mechanics, or an added pitch to their arsenal. Keep in mind, in most cases, you should be shifting your perspective of pitchers only from a positive change, rarely when a pitcher underperforming as they ramp up for the season’s premier.

There is also one general rule I follow that I want to pass to you:

Veterans usually start slow in the spring. Younger arms generally show up to camp ready.

You should be expecting older arms to ramp up their velocity with more starts, especially as they experiment in earlier outings. They also have more experience to know what tweaks and adjustments to make in time for the start of the season.

Meanwhile, younger arms generally have something to prove, say for a rotation spot or they are itching to define themselves among the team. It generally means what you see early is what you get.

Keep that in mind as we dive into all thirty MLB rotations. For the sake of your readability, I’ve made this an easy checklist for each starter in every rotation. No long paragraphs, just the good stuff.


Arizona Diamondbacks


  • Zac GallenIs he leaning a little more on changeups? Can he get strikes with sliders and curveballs?
  • Madison Bumgarner – Can he get back to 90/91 mph velocity? Bumgarner can be a huge sleeper if his velocity is back up.
  • Caleb Smith – Is he throwing strikes + maintaining 92/93 mph?
  • Luke Weaver – Watch his slider usage and if it can constantly get strikes. He needs that pitch to prevent hittable fastballs.
  • Merrill Kelly – 92/93 mph velocity with curveballs or cutters for strikes.




  • Max Fried – Is he in rhythm with his curveball?
  • Ian Anderson – Still having trouble nibbling around the zone? Has his curveball improved?
  • Charlie Morton – We want to see 94/95 mph velocity to feel comfortable.
  • Drew Smyly – He showcased a 94/95 mph heater last September and we want to see that again.
  • Kyle Wright – Is he able to limit the walks and hit edges?


Baltimore Orioles


  • John Means – Is he at 94/95 mph on his heater? Is his changeup nailing the bottom of the zone? Are his slider and curveball forcing their way into the conversation?
  • Felix Hernandez – If he can’t get above 90 mph consistently, this won’t be worth it.
  • Jorge Lopez – Unless something dramatically changes, he’s not worth the look
  • Keegan Akin – Keep the same 94 mph velocity
  • Dean Kremer – Be the same guy from September.


Boston Red Sox


  • Nathan EovaldiIs his fastball + cutter combination working well? Is he comfortably pumping 97+ mph?
  • Eduardo RodriguezFirst, let’s make sure he’s healthy n all. Check to see if he’s able to get his slider/cutter over the plate for strikes.
  • Garrett RichardsCommand is everything here. The more strikes, the better.
  • Martin Perez – He excelled when he had 94 mph velocity and a solid cutter to boot. Without that, we’re not interested.
  • Nick PivettaIs he forcing himself into the rotation over Tanner HouckLet’s cross our fingers his fastball is back at 94/95 mph and he’s able to throw 45%+ breaking balls.


Chicago Cubs

  • Kyle Hendricks – Are you still the command freak you’ve always been?
  • Jake Arrieta – Can he sit 93/94 mph again? Is he getting whiffs with his cutter?
  • Zach Davies – If that changeup is cruising with 35%+ usage, you should feel safe drafting him.
  • Alec Mills – Is he finding the edges and stealing strikes effectively?
  • Trevor Williams – Is the slider usage still above 25%? Can it get strikes?
  • Adbert Alzolay – How is his control? His biggest question mark is his pitch efficiency.


Chicago White Sox

  • Lucas Giolito – Do you have a whiff-heavy breaker?
  • Dallas Keuchel – Command still there?
  • Lance Lynn – Still 93/94 mph velocity?
  • Dylan Cease – Is his command fix? Like for real this time? Watch his slider and curveball specifically, while hoping we get few heaters missing up and arm-side.
  • Caros Rodon – Monitor his slider. Is he getting 45%+ swings on them? That pitch is everything for Rodon.
  • Michael Kopech – Is he back up to near triple-digits velocity? How do his slider and changeup look?


Cincinnati Reds

  • Sonny Gray – Is he getting strikes with his slider and curveball?
  • Luis Castillo – Fastball command okay? How is his slider developing?
  • Tyler Mahle – Track that slider. Is it low in the zone and getting whiffs? Is he using other secondary pitches instead?
  • Wade Miley – Remember him? His cutter created his success, check to see if it’s jamming right-handers effectively.
  • Michael Lorenzen – Is he able to keep his 96 mph velocity? Are his slider & changeup getting whiffs? Are his cutter and sinker getting smacked around?




  • Shane Bieber – How’s the changeup coming? Is his new cutter still fantastic?
  • Zach PlesacAs long as his slider and changeup are both getting whiffs, everything is fine. Is he still exclusively throwing them to just righties (sliders) and lefties (changeups)?
  • Aaron Civale – He has a new arm circle, throwing more four-seamers, and now has a split-change. Let’s see if it all works.
  • Triston McKenzie – Is his fastball at 94 mph? Are both his slider and curveball working?
  • Logan Allen – Is he going to win the #5 spot?
  • Cal Quantrill – Is he going to win the #5 spot? Also, are any of his secondary pitches noteworthy?


Colorado Rockies


  • German Marquez – Is his slider doing wonderful things?
  • Kyle Freeland – He needs to be hitting the edges with heaters or this is doomed.
  • Antonio Senzatela – Something new needs to happen
  • Jon Gray – Is he back to 96 mph?
  • Austin Gomber – How dominant is that curveball? Does it matter?


Detroit Tigers


  • Matthew Boyd – Is his slider back? Is that changeup still getting whiffs? 92/3 mph velocity should do the trick.
  • Spencer Turnbull – Please tell me he’s axing that sinker. PLEASE. Meanwhile, are both his slider and curveball missing bats?
  • Michale Fulmer – Ha. He needs to return to hovering 96 mph velocity with a solid slider and changeup. We can only hope.
  • Jose Urena – If he’s hitting the edges with a 95/96 mph sinker, there’s hope for a Toby in here.
  • Julio Teheran – Can he get back to 90/91 mph velocity? Is his slider missing bats again?
  • Casey Mize – How is his splitter consistency? Is he leaning on his cutter for strikes effectively?
  • Tarik Skubal Focus on his secondary stuff. Is he featuring them heavily and getting strikes with them?



Houston Astros


  • Zack Greinke – Don’t worry about his velocity. It’s always slow.
  • Lance McCullers Jr. – How’s the cutter? Does he have a proper secondary pitch to get strikes outside of his curveball?
  • Jake Odorizzi – Is he painting the top of the zone with 93 mph heaters? Don’t worry about the secondary stuff.
  • Jose Urquidy – Are the whiffs returning on his slider and curveball?
  • Cristian Javier – Has he developed the stamina to push 93 mph as he progresses through the start?


Kansas City Royals


  • Danny Duffy – Should be 92/93, I wonder if he’ll keep his elevated curveball usage for strikes in zone.
  • Brad Keller – 93/94 mph is ideal. His breaker had its moments last year, let’s hope it keeps up (by locating it down).
  • Mike Minor – Can he get his 92/93 mph back? Lost two ticks last season.
  • Brady Singer – Does he have a strikeout pitch?
  • Kris Bubic – Is his command good enough to deserve the #5 spot?
  • Jakob Junis – Is his slider forcing him into the rotation?

Los Angeles Angels


  • Shohei OhtaniIs he still falling behind in counts constantly?
  • Andrew Heaney – Look for pitch separation: fastballs up, curveballs down and glove-side, changeups down and arm-side.
  • Dylan Bundy – Is he comfortably at 91 mph through outings? First pitch curveballs back? Please no mistake sliders deep in counts.
  • José Quintana – Can he get strikes with his curveball & hit edges with heaters?
  • Alex Cobb – Has driveline changed him? How is “The Thing” (his splitter) looking?
  • Griffin Canning – Is he getting into deep counts often? How are the breaking pitches?


Los Angeles Dodgers


  • Clayton Kershaw91 mph velocity still there?
  • Trevor Bauer – Are his spin rate numbers still incredibly high?

    This is great work, as always. Will you be updating this and answering these questions toward the end of camp?
