MINNEAPOLIS — For most of the summer, Aaron Boone managed the same tightrope almost every night. A thin group of trusted relievers. A string of one-run games. A pattern of leaning on the same two or three arms until they were nearly spent.
The Yankees survived it. Their pitching staff carried the club through a brutal stretch for the bats and kept them in the American League East race. But the cost showed. A handful of high-leverage arms absorbed far too much of the load, and October is no time to run on fumes.
Help may be arriving from an unlikely place, and it throws harder than anyone the Yankees have used all year.
The name has floated around the organization’s plans since spring, always with the same caveat. First the timeline slipped. Then an injury stopped it cold. Now, at the most important stretch of the season, the door has quietly reopened.
Carlos Lagrange, the Yankees’ hardest-throwing prospect, is back on a mound in game action. The right-hander was slated to pitch for Triple-A Scranton/Wilkes-Barre, his first official appearance since June 28. It is the clearest sign yet that a fastball touching 103 mph could factor into the Yankees’ bullpen before the regular season ends.
The stakes are simple. New York entered the Twins series second in the AL East and pushing for a division title it has not won since 2019. A fresh power arm, even for a handful of innings, would give Boone a weapon he has not had. The question is whether there is enough runway left to get Lagrange ready in time.
A plan that kept getting interrupted
Lagrange, 23, has never pitched in the majors. He has spent 2026 at Triple-A, where his stuff has drawn attention well beyond the Yankees’ system. MLB Pipeline ranked him as the organization’s No. 4 overall prospect and No. 2 pitching prospect earlier in the year.
The Dominican right-hander built his reputation on velocity. His four-seam fastball has reached 103 mph and averaged near 99. He backs it with a hard slider that grades as a plus-plus pitch. Earlier this season he threw the fastest tracked pitch in the minors, and in one Triple-A start he hit 102 mph three separate times while striking out eight.
The Yankees made a deliberate move in June. They shifted Lagrange from the rotation to the bullpen at Scranton/Wilkes-Barre. The organization still views him as a starter long term, but the relief experiment was designed to fast-track his electric stuff to the Bronx without derailing that development.
Then the plan stalled. In early July, Lagrange was diagnosed with a capsular sprain in his right shoulder. He was shut down for roughly six weeks and did not appear in a game for more than two months. Before the injury, he had gone 1-4 with a 4.55 ERA in 18 Triple-A appearances, including 11 starts.
Boone has not ruled out a role for Lagrange over the final weeks. The manager has said the organization believed the young right-hander could help the Yankees out of the bullpen without disrupting his path as a starter. His return to the mound is the audition that decides whether that idea becomes real this year.
A bullpen that has been asked to do too much
The context around Lagrange’s return explains the urgency. The Yankees’ bullpen ranked 23rd in the majors in ERA in 2025, and the group lost two key arms over the winter when Devin Williams and Luke Weaver signed with the crosstown Mets. New York largely ran back the same unit.
David Bednar has anchored the back end as one of the sport’s most reliable closers, finishing more games than anyone in baseball this season. In front of him, Boone has leaned heavily on Brent Headrick and Paul Blackburn, both of whom emerged into high-leverage roles and both of whom have piled up appearances. Fernando Cruz has dealt with injury. Early offseason bets on Camilo Doval and Jake Bird failed and both were traded.
That is the backdrop. A staff that has carried the roster, and a small circle of arms that has shouldered the tightest innings. A pitcher who can pump 100 mph and miss bats at a 40-plus percent clip is exactly the kind of reinforcement a tired bullpen needs in September.
Comparison that raises the ceiling: a Betances-sized upside
Here is the detail that gives the story its edge. Evaluators have pinned a specific relief ceiling on Lagrange, and it is not a modest one. Baseball America’s scouting report frames his bullpen outcome as a potential hammer in the mold of Dellin Betances, the former Yankees setup man who once anchored some of the most dominant relief units in franchise history.
The scouting grades explain why. Lagrange’s fastball earns a 70 grade. His slider earns a 70 as well. Those are the tools of a late-inning force. The concern lives in his control, graded well below average, a product of a tall frame and long levers that scouts worry will cap his command.
That profile is the entire argument in one line. In a starting role, the control questions matter over six innings. In one-inning bursts, a reliever can let the fastball and slider play at full effort and hide the rest. It is precisely why the Yankees moved him to relief in the first place, and why his return carries more weight than a typical September prospect cameo.
The timing remains tight. The RailRiders’ minor-league regular season ends later this month, which leaves only a short window for Lagrange to build up and prove he is ready. There is no guarantee it ends with an MLB debut. But the Yankees have kept the possibility alive on purpose, and the clock is now the only thing standing between a triple-digit arm and a bullpen that could use one.
Following the Twins series, the Yankees open a set with the Arizona Diamondbacks on Friday in Phoenix. Lagrange’s progress at Triple-A will be tracked closely from the Bronx with each outing he makes.
