The Washington Nationals haven’t pitched properly this season. Using 41 completely different hurlers — probably the most within the majors — the NL East membership ranks fourth from the underside in each ERA and FIP, and has the fifth-worst strikeout fee. With a handful of exceptions, the often-patchwork employees has been mediocre at greatest.
The longer term is nonetheless promising. Underneath the management of Paul Toboni, who was named president of baseball operations 11 months in the past, the Nats have forged apart their old-school methods and tailored an analytically pushed strategy to securing outs. Bringing on board Simon Mathews as pitching coach and Grayson Crawford as director of pitching have been particularly significant steps within the group’s much-needed retooling.
Retaining Sean Doolittle was likewise a shrewd transfer. Now the assistant pitching coach after serving as pitching strategist in 2024 and 2025, the 39-year-old former nearer is simpatico with Toboni, Mathews, and Crawford in relation to modern-day strategies. Information savvy whereas additionally bringing a been-there-done-that understanding of what interprets to success on a giant league mound, Doolittle is a crucial a part of what the Nationals are working to construct.
Doolittle sat down to speak pitching when the Nats visited Fenway Park earlier this summer season.

Sean Doolittle: “One factor that we’ve paid numerous consideration to this yr is getting guys to make use of each of their fastball shapes, even to off-handed hitters. For our group, that’s been new. We don’t have a ton of velocity, so we’ve got to be actually acutely aware of our combos and our sequencing. I believe it’s helped a couple of guys in our group fairly a bit this season. Guys like Brad Lord have thrown much more sinkers this yr to lefty batters. It’s nonetheless not a high-percentage-usage pitch for him, however general it’s been a giant a part of our schooling course of with serving to our pitchers and our catchers learn swings and sequence. Sport calling and stuff like that.”
Laurila: I imagine Andrew Alvarez is throwing extra two-seamers this yr?
Doolittle: “Yeah, that’s one other man who has thrown extra. Particularly for a man like him who can create that outlier angle — his launch top and his VAA — along with his two-seam. He throws from a weirdly excessive slot. With in-zone sinkers he can get down into the negative-8, negative-9 vary along with his strategy angle. That’s a part of his superpower. He can create some bizarre angles and shapes from that prime slot.
“Different issues we’ve been enthusiastic about right here… it’s fairly foundational, the stuff we’re doing. There’s been an enormous emphasis on schooling. We’ve received our guys sporting Pulse [monitors]; we’re nonetheless studying and refining their routines and workloads, not simply of their outings, but additionally the times they’re not pitching. We’re making an attempt to maintain our guys recent whereas additionally ensuring they get their work in. A number of our course of is going on behind the scenes. Seam orientation has additionally been a giant emphasis for our group.”
Laurila: Simply how in another way are issues being carried out in comparison with current seasons?
Doolittle: “It’s extremely completely different, and in a great way. That is my third yr right here, and we’ve got folks up and down the group now that may spot issues like pitches that aren’t being optimized with seam orientation, and we will begin to make these changes even earlier than guys get right here. Then we’ve got the flexibility to proceed that course of as soon as they’re right here, whether or not it’s spin-axis balls or utilizing Edgertronic to trace that sort of stuff. Each day, we’re making an attempt to maneuver issues on the margins. We’re actually leaning into these sorts of issues.”
Laurila: How a lot of a studying curve has it been for you?
Doolittle: “The seam-orientation stuff has been most likely the world I’ve realized probably the most about. I believe I already had a fairly good understanding of numerous the opposite stuff. And one other space of schooling has been persevering with to study being a coach. There’s an artwork to it, to educating and incomes the belief of a participant. It’s not simply getting them to purchase into the changes, but additionally to exit in a giant league recreation and belief the issues we’ve been engaged on.
“I skilled below Simon once I was nonetheless a participant. He had simply transitioned himself from taking part in to teaching throughout the offseason after the 2020 season, and I realized rather a lot from him in that point. We’ve stayed shut within the years which have adopted, as he climbed the ladder within the Reds group and I used to be transitioning to teaching. He was a giant useful resource for me, and I proceed to be taught stuff from him on a regular basis.”
Laurila: The group actually has different educated folks engaged on the pitching facet as properly…
Doolittle: “Grayson Crawford, our director of pitching, is extraordinarily good. His superpower might be the seam-orientation stuff. Simon’s superpower is communication, constructing belief and relationships. That’s to not low cost his data of pitching, his data of expertise, of pitch design and biomechanics. The processes he’s been constructing for our group, together with our biomechanics experiences, our after-action experiences — the stuff that we’re utilizing to watch our pitchers each day; he introduced Pulse over with him from Cincinnati — have actually helped our gamers perceive their routines. The way in which that his mind works makes him completely the proper man to assist us lay that basis and construct one thing particular.”
Laurila: Altering course a bit, does anybody on the pitching employees have an outlier pitch? Not mandatory when it comes to high quality, however slightly there’s something that makes it atypical, if not distinctive. Josh Hader’s fastball could be an instance.
Doolittle: “Not likely. Cade Cavalli’s sweeper is possibly the closest factor, however it’s a one-seam, seam-shift sweeper and that’s not… I imply, it’s exceptionally good for what it’s, however I don’t suppose it’s fairly an outlier just like the Hader instance.”
Laurila: Atlanta’s Dylan Dodd is much like Hader. Speaking to him earlier this season, I realized that he tried a sinker grip as a result of his four-seamer didn’t have good metrics, and the outcome was a two-seamer that has good four-seam motion.
Doolittle: “That’s loopy. It’s actually fascinating, as a result of… I imply, we’ve made some grip changes with guys as a result of the orientation was out of whack for the best way that they’re biased to maneuver — pronator/supination bias — however I can’t consider anyone fairly like that the place it was as a lot of a lightbulb second. We’ve moved some issues on the margins, for positive. However actually, Cavalli is one of the best instance right here. He didn’t have that final yr.
“He could be an instance, too, with the fastball. Coming off of Tommy John surgical procedure, during the last couple years he was actually making an attempt to trip the four-seam, and received to a degree the place we have been like… that was truly one of many issues I began engaged on with him final yr. He was so biased to supination {that a} high-ride four-seam didn’t seem to be it was within the playing cards for him. I instructed him that we should always lean right into a cut-ride form. He’s been in a position to play with the four-seam and develop an precise cutter off of the cut-ride four-seam. He’s a enjoyable man to work with. He can get the ball to do nearly something he needs. After which when Simon got here in he added the sweeper. That was one among his large initiatives in spring coaching. Cade’s capacity to spin the curveball made us suppose he’d be capable of decide it up fairly shortly, and he did. He’s made Simon and the remainder of us look actually good.”
Laurila: To what extent may you make the ball do what you needed?
Doolittle: “Little or no. I threw 90% four-seams for my complete profession. I attempted so many issues, particularly within the again half of my profession, so as to add a secondary pitch. I used to be choosing participant’s brains, I used to be spending offseasons doing pitch design, however I simply didn’t have the hand really feel to do it. If I knew then what I do know now, possibly I’d have been in a position to make extra progress.
“That interprets to the job I’ve now. I can use my expertise making an attempt all of these various things and being taught all of these completely different cues, and choosing gamers’s brains on what their thought course of was on their pitches. I’m in a position to educate it at a excessive stage, regardless that I wasn’t personally in a position to do it.”
Laurila: That mentioned, a pitcher nonetheless wants the hand really feel, which is one thing you possibly can’t educate. It’s mainly innate. Proper?
Doolittle: “To an extent. I do suppose it’s innate, however the fortunate factor for me is that these days nearly all people at this stage has extra hand really feel than I had. I imply, I used to be a transformed place participant. I received tremendous fortunate that the fastball I threw was an outlier pitch for the time that I performed. There’s a message to that, too. Pitch to your strengths, be nice at what you’re good at. Proper? In case you have one thing in your arsenal that makes you distinctive, get f—ing good at executing it at a excessive stage.
“It took me some time to grasp that it’s OK if a hitter is aware of, or thinks he is aware of, that this pitch is coming. If it’s a pitch that you just get actually good at executing, you should use that to your benefit. You may exploit that. Present them what they need to see and get them to interact with it in your phrases. There’s something to that, for positive.
“In fact, with the issues that we’ve got now, just like the Edgertronic cameras and spin-axis balls, we will run experiments and get a lot better real-time suggestions than what was obtainable once I performed. We’re in a position to assist guys make changes. Via the artwork of teaching, we’re in a position to get them to verbalize what they’re considering and feeling, after which make changes off of that, begin to practice the hand really feel for a particular pitch sort.”
Laurila: You had numerous pitching coaches over the course of your taking part in profession. Do any of them stand out when it comes to being forward of the curve?
Doolittle: “Sure. My first pitching coach [in MLB], and the one I used to be most likely with the longest in my profession, was Curt Younger, in Oakland. I used to be with him earlier than we had an understanding of analytics and the way these issues have been monitoring. I actually appreciated every thing that he did for me, serving to me set up myself within the league.
“Extra not too long ago, in 2021 I signed a free agent deal to go to Cincinnati particularly due to Derek Johnson. He was Simon’s mentor. My understanding of pitching grew exponentially below him. Like Simon, his superpower was his communication, his capacity to inspire gamers and meet them the place they’re at of their profession. He may get high-level ideas throughout to them in an accessible method.
“I used to be additionally with Pete Woodworth in Seattle, though just for about 5 or 6 weeks in 2021, so I didn’t have as a lot time with him. He’s excellent. However I’d say that DJ is the man. Once I took this job, I instructed Simon that I’m making an attempt to do a Derek Johnson impression.”
