New York Yankees right-hander Will Warren has posted a 0.87 ERA through multiple MLB Spring Training outings in 2026, making him one of the most efficient arms in the Grapefruit League. Skipper Aaron Boone praised Warren’s work after his latest start, calling it “real efficient, another good one” and noting clear growth across the young pitcher’s spring appearances.
Warren’s run has drawn attention from those tracking Yankee rotation depth heading into the regular season. A sub-1.00 spring ERA does not guarantee a roster spot, but it does signal command and sequencing that often show up in better FIP and zone-rate figures once April arrives. The numbers suggest Warren is throwing with purpose.
Saturday’s outing added three strikeouts to a ledger that already looked clean. Warren acknowledged the performance was not flawless, saying his stuff “wasn’t as sharp as I wanted it to be, especially there late” — the kind of self-scouting that pitching coaches prize in a young arm trying to carve out rotation innings.
How Warren Has Performed in MLB Spring Training 2026
Warren has been the steadiest arm in Yankees spring camp, lowering his ERA to 0.87 across multiple Grapefruit League starts. His March 1 outing in Clearwater against the Phillies produced 3 2/3 scoreless innings. His follow-up Saturday added three more strikeouts to a spring line that reflects both efficiency and durability for a pitcher still building his major-league profile.
That Clearwater start laid the foundation. Warren threw 3 2/3 scoreless frames, and Boone said he noticed a “nice progression” carrying from that outing into the next. For a pitcher working to lock down a rotation spot on a staff carrying significant payroll at the top, back-to-back clean spring starts carry real weight in the organizational depth conversation.
Warren’s strand rate and contact management tell a deeper story than ERA alone. Even when his secondary stuff dipped late — by his own admission — he competed through contact rather than collapsing. That durability signal shows up in left-on-base percentage once the regular season data stacks up, and it separates arms who sustain success from those riding a single pitch.
For context, a 0.87 ERA across multiple Grapefruit League starts ranks among the better spring marks for any back-end candidate in recent Yankees camps. Pre-arbitration pitchers who post sub-1.00 spring ERAs have historically earned at least an extended look in April, whether in the rotation or in high-leverage relief roles.
What Boone Said About Warren’s Development

Boone described Warren as “steady” throughout camp and said the growth from his first start to his most recent outing has been clear. The phrase “real efficient, another good one” reflects the measured confidence a manager uses when a young pitcher is doing the right things without yet holding a guaranteed roster slot.
Boone’s word choice has been deliberate throughout camp. He did not call Warren dominant. He called him steady and efficient — terms that, in the Yankees’ organizational vocabulary, often mean a pitcher is managing counts, working to contact when needed, and avoiding the multi-run innings that inflate spring ERA and erode a manager’s trust. Based on these two starts, Warren fits that description.
The counterpoint is fair: spring training ERAs are volatile. Hitters arrive at different conditioning stages, lineups shuffle daily, and the Grapefruit League rewards pitchers who locate well against batters still finding their timing. Warren’s 0.87 ERA is encouraging. The real test comes in April, when opposing lineups are locked in and operating at full strength.
Other Yankees Spring Camp Storylines
Beyond Warren’s pitching, Yankees camp has produced other notable moments. Boone highlighted outfielder George Lombard’s versatility, noting that Lombard has “swung the bat really well” while also playing what Boone called “phenomenal defense” — including a start at shortstop Saturday night, a position that demands elite athleticism from any player asked to handle it.
The most striking subplot involves 17-year-old pitching prospect Contreras, son of former MLB pitcher José Contreras. The younger Contreras, committed to Vanderbilt University, faced the Yankees’ lineup during a spring session and drew direct praise from Boone.
“We see a lot of impressive things in sports these days, but yeah, a 17-year-old running up against that lineup, it’s pretty cool,” Boone said. The moment carries baseball’s generational weight — a teenager with his father’s last name and his own arm testing himself against a big-league roster. That kind of scene does not show up in a box score, but it lingers in a clubhouse.

What Warren’s Spring Means for the Yankees Rotation
Warren’s spring efficiency puts him in position as a legitimate candidate for a back-end rotation role or a high-leverage bullpen assignment when the Yankees break camp. A 0.87 ERA does not lock up a roster spot, but it forces the front office to account for him in depth planning — particularly given the financial value tied to pre-arbitration pitchers who outperform their cost.
The Yankees carry one of baseball’s largest payrolls, which means rotation decisions involve both performance and financial planning. A young, cost-controlled arm at Warren’s spring level gives the club flexibility. That freedom matters because it frees dollars for other moves. If his command holds through the final weeks of camp, the Yankees face a productive problem: too many arms performing well for too few spots.
The film shows a pitcher who is not overpowering hitters but is executing a clear plan. His self-awareness about the late-inning dip Saturday suggests a pitcher engaged in real-time adjustment, which is the developmental marker that separates durable arms from those who rely on one pitch. Based on available data from these starts, Warren looks like a pitcher the Yankees can trust in meaningful situations.
