Jarlin Susana came to the Arizona Fall League looking for innings. He’s leaving with a trophy.
The Nationals right-hander was named the 2026 AFL Pitcher of the Year after a fall in which he did exactly what Washington wanted: get back on a mound, stack competitive reps and show that the raw stuff still plays at a ridiculous level. For Susana, who had thrown only 76 2/3 innings over the previous two seasons combined and missed time in 2025 with a UCL sprain before season-ending lat surgery, the assignment was straightforward.
Get healthy enough to pitch. Get back into a rhythm.
Stay himself.
“They told me to stay the same,” Susana said during AFL media day before opening day. “I was good before.
I’m still good now. Just making sure I do minor adjustments with how I position my arm, but otherwise, stay the same.
I’m still the same me.”
That version of Susana is built on power. The 6-foot-6 right-hander, ranked No. 66 on MLB Pipeline’s Top 100, had already touched 104 mph in the Triple-A Championship Game before arriving in the desert, and he backed it up immediately by hitting 103.8 mph in his first Fall League start. Across six starts and his Fall Stars Game appearance, he averaged 100.7 mph with his fastballs, according to Synergy.
The numbers behind the heat were eye-popping. Susana led the AFL with 26 strikeouts in 18 2/3 regular-season innings, then added five more in 2 2/3 innings in Salt River’s playoff quarterfinal on Friday.
Statcast tracked 188 pitches in the Fall League at 100.0 mph or harder, and Susana was responsible for 165 of them - 87.8 percent. He also owned the top 77 hardest-thrown fastballs in the league, and every one of those came in above 101 mph.
He did it with more than one fastball, too. Susana leaned on both a riding four-seamer and a sinking two-seamer, and both sat in triple digits.
That mix, paired with a high-spin slider, made him a nightmare to square up. Salt River pitching coach Jerry Sullivan, who works in the Rockies system, put it plainly earlier this fall.
“When you’re not losing velo and changing shapes, it helps,” Sullivan said. “He goes to a four-seamer, and some of them have 15 [inches] of ride, and then he drops to 2-and-18 [of vertical and horizontal movement] on a sinker, and it’s running at you.
But you’re committed as if it’s a four-seamer. And it’s 102.
I mean, good luck.”
Susana’s breaking ball was just as nasty. Sometimes labeled a slider, sometimes a curve, and at times showing more of a sweeper look, it gave hitters another problem to solve. Nine of his 68 recorded pitches with spin rates of 3,000 rpm or higher were on that pitch, and all nine produced a 76 percent miss rate.
“His kind of plays like a larger death ball,” Sullivan said. “That’s why you’re getting the early swings on it because it’s in zone longer.
The velocity is extremely high on it, sometimes around 87 or 88 mph. You have to pull the trigger quick.”
Even with all that swing-and-miss, the command remains the piece Susana still has to sharpen. He walked 13 batters in those 18 2/3 innings, and his minor league track record has never featured pinpoint control, with a 4.8 BB/9 rate. The Nationals, though, were encouraged by what they saw after such a condensed season.
“Overall, we are very pleased with how Jarlin threw in the AFL,” Nationals assistant general manager Devin Pearson said. “The goal in sending him out there was to continue to build up his workload and refine his shapes and locations.
There aren’t many people in the world who can do what he can in terms of velocity and spin, so it was really about getting more reps and finding consistency since he had a condensed season. I know he had a blast out there.”
The organization’s hope now is that this Fall League run becomes the launch point for a healthier, steadier 2027. The ceiling is obvious.
The stuff is already special. What remains is finding the zone more often, working more efficiently and turning those raw tools into the kind of consistency that can carry him as a frontline starter.
“Turning to 2027, the hope is to just continue to build off of what he was able to do this year,” Pearson said. “Can we get even more consistent with strike throwing?
Can we make his super powers even better by finding more consistent fastball and secondary shapes, can we dominate 0-0 counts to be in advantage counts more often? Our expectations are that he comes into camp ready to compete and take someone’s spot.

Nationals Prospects Just Put More Focus On A Tough Roster Decision
R.J. Sales got the start in a Salt River game that ended with the Javelinas edging the Rafters 6-5 and closing out the season, and he was one of several Nationals prospects to get a look in the finale. Sales worked 3 1/3 innings, allowing five runs on seven hits and a walk while striking out four, and Kevin Bazzell, Teo Banks and Noah Dean also appeared as Washingtons pipeline kept drawing attention in the desert.
The bigger picture for the Nationals is arriving quickly, with the offseason now in view and the deadline to add players to the 40-man roster getting closer. For a front office that has to weigh development against protection, these late-season performances matter, and the situation is made even trickier by the possibility of an MLB lockout and union decertification hanging over the winter.

Marlins Just Added A Familiar Name In A Very Different Role
The Marlins made a notable front-office addition this week by bringing in former outfielder Trayce Thompson for a baseball operations role, a move that also signals the end of his playing days. For a division rival like the Nationals, it is another reminder that the offseason is not only about roster churn on the field, but also about the people being added behind the scenes as clubs reshape how they evaluate and develop talent.
Around the league, the pitching market is still moving too, with the Braves signing reliever Evan Phillips and the Tigers adding Emilio Pagan while both teams remain linked to a possible reunion with Raisel Iglesias. Washington has made its own back-office move by hiring John Morris as its new vice president of baseball research, a step that fits into the broader push to sharpen the organizations decision-making even as other NL East clubs keep tweaking their own infrastructure.

Nationals Are Betting Their Pitching Fix Starts Far From The Mound
The Nationals are treating their pitching overhaul as more than a simple search for arms. This offseason, the organization has put real emphasis on building up the infrastructure around the staff, adding John Morris as vice president of baseball research and David Besky as pitching strategist while also looking to expand both the analytics and scouting sides of the operation. It is a clear sign the club wants better answers on the mound, but also better processes behind the scenes.
Washington also plans to bring in more pro scouts, a move aimed at sharpening player evaluation and giving the front office more ways to identify pitching help. The hope is that these changes will show up not just in acquisitions, but in how the Nationals develop pitchers and shape the staff for the 2027 season. The work is early, and the payoff is still ahead, but the direction is obvious: the fix is starting well before anyone throws a pitch. [Read more 🡒]
