Rockies Prospect Stu Flesland Is Forcing A Bigger Pitching Question

Young pitching sensation Stu Flesland III makes waves in the minors, showcasing his potential and versatility despite a few bumps in the road.

SCOTTSDALE, Ariz. -- Stu Flesland III spent most of the spring and summer making life look easy, with one ugly night in mid-May standing out like a bad inning that refused to leave.

The Rockies left-handed pitching prospect, a 2023 11th-round pick out of the University of Washington, opened the year in his hometown with High-A Spokane. His parents were in the seats, watching him pitch where he once dreamed about reaching pro ball. Out on the mound, he could hear friends calling out to him, and it felt, as he put it, “like a high school thing,” he said.

He overwhelmed hitters there, piling up 19 strikeouts in 17 1/3 innings before Colorado bumped him to Double-A Hartford. Once there, he turned in a 1.88 ERA over 18 games, 12 of them starts.

The detour through Triple-A Albuquerque, though, brought both ends of the spectrum. Before he officially joined Hartford on May 19, the Rockies had him cover a few innings at Triple-A twice.

The first appearance was clean: three scoreless innings. The second went off the rails fast.

Against Oklahoma City, Flesland was tagged for nine runs on eight hits and four walks in one inning. Alex Freeland and Jack Suwinski both homered off him, and both had Major League at-bats behind them.

It was the kind of outing that can shake a pitcher if he lets it. Flesland took it as a lesson.

“It was not a small thing,” Flesland said. “I figured that a lot more guys are looking for what kind of pitches you’re tipping, and I needed to have a closer eye on that.

My second outing didn’t go well. I had a meeting with my pitching coaches, and they let me know that’s why things went that way.”

The numbers in the Arizona Fall League told the same story. Flesland finished the regular season with a 6.94 ERA while facing some of baseball’s best prospects, and that mark climbed after he allowed five runs on five hits and one walk in two innings. But he answered in the playoffs on Thursday, holding the Mesa Solar Sox to one run on three hits and one walk across 3 1/3 innings.

At 6-foot-5, Flesland brings a look and delivery that can make hitters uncomfortable when everything is synced up. His arm slot is neither especially low nor especially high, and the ball can be tough to pick up if he keeps his shape consistent. The problem, by his own admission, was giving away too much.

“When I come set, I’m very closed off, but I was more closed off on certain offspeed pitches, so they were able to pick what they wanted to go for,” Flesland said. “But it was a great thing, a learning experience. That is going to help me as I move up.”

That playoff outing fit the larger arc of his year, especially after Hartford needed him. Injuries and promotions had thinned out what once looked like a league contender, and manager Robinson Cancel’s club was fighting to find its footing late. Flesland said that setting gave him an extra edge.

“I had that chip on my shoulder and wanted to get to Double-A and make an impact,” he said. “I had played for Robbie before and I knew a bunch of the guys there. It was a comfortable atmosphere to walk into, and they were in the middle of a playoff push.”

His stuff is built around a four-seam fastball that sits just under 92 mph and a sinker that comes in just above 90 mph. His changeup and slider are meant to arrive at different speeds, and once he got to Scottsdale, he said he would work with Rockies coaches and analysts at Salt River to look for adjustments that could help him add more velocity at the top end.

“Stu had a great year,” Rockies roving pitching coordinator Dan Meyer said. “We want him to finish strong.

We thought he’s earned this honor to play in the Fall League. We want to continue to refine.

He’s deceptive, a little funky. But he has good stuff.”

Flesland has started and relieved at both the college and pro levels, and he’s comfortable in either role. Even his look carries a throwback feel, with the 1890s-style handlebar mustache drawing attention and a resemblance, at least in style, to Rollie Fingers, the right-hander who pitched from 1968-85 and became a Hall of Famer as a reliever.

Rockies Finally Have Trade Leverage To Address Their Biggest Problem

The Rockies are suddenly in a position they have not enjoyed often enough in recent years: they have enough outfield depth to create real roster flexibility. President of baseball operations Paul DePodesta said the club has seven or eight players capable of contributing at the major league level, a surplus that gives Colorado something it can actually work with as it looks to improve a roster that badly needs pitching help.

Colorados biggest issue remains obvious after finishing the 2026 season with the worst team ERA in the league, and that is where the front office will likely focus its attention. DePodesta also pointed to depth at second base, another area that could help the Rockies in trade talks, giving them multiple ways to build leverage as they try to turn excess position-player depth into arms that can stabilize the staff.

Rockies Young Bats Just Put Real Pressure On One Big Weakness

The Rockies spent most of 2026 buried by pitching, not by a lack of life in the lineup. Even in a 104-loss season, the position players gave the club something to build around, with Hunter Goodman, Cole Carrigg, TJ Rumfield, Jake McCarthy, Charlie Condon and Mickey Moniak all helping keep the offense from going completely dark while the rotation unraveled after the trade deadline.

That contrast is what makes the offseason so interesting in Denver. If Colorado can get even ordinary work from its pitching staff, especially the starting rotation, the same young bats that flashed through a lost year could make the roster look a lot more competitive next season. The offense has already shown enough to suggest this is not a total teardown, but the margin for progress still runs straight through the mound. [Read more 🡒]

Orioles Fans Have A New Reason To Watch Vance Honeycutt Closely

The Arizona Fall League handed out its annual awards this week, and Vance Honeycutt picked up Defensive Player of the Year honors after a strong showing in the desert. The recognition adds another layer to a prospect whose name has already been circulating among Orioles fans, alongside a list of league winners that included Welbyn Francisca as MVP and Tai Peete as Offensive Player of the Year.

For Baltimore, Honeycutts award is another reminder that his value is not just tied to what he does at the plate. Defense can be the separator for young players trying to carve out a role, and this kind of accolade gives his profile a little more shine heading into the next stage of his development. The Fall League is often where prospects make a final impression before the offseason settles in, and Honeycutt left one worth noting. [Read more 🡒]
