Ryan Feltner is finding a new lane with the Rockies, and Sunday’s 2-1 loss to the Mariners gave another look at how that might work.
Normally a starter, Feltner came in behind Tomoyuki Sugano and handled the next three innings at Coors Field as Colorado kept testing a “piggyback” setup - one pitcher follows another to cover multiple innings, maybe even the finish. It’s not Feltner’s preferred role, but it’s one he’s willing to keep exploring as the Rockies sort through ideas in a season built around experimentation.
That was on display against Seattle. Sugano worked the first five innings and allowed one run, then Feltner gave up one run over three innings before Jimmy Herget finished the ninth.
Hunter Goodman’s one-out homer in the final inning briefly stirred a comeback, but Brett Sullivan struck out with two runners on to end it and hand Colorado loss No. 99.
Feltner said the concept makes sense, especially for a team still trying to figure out the details.
“Communication is the main thing when you are trying a system like this, because when you’re dealing with starters - very routine-oriented people - you need to know at least what the general game plan is,” said Feltner, who has made 22 starts this season. “I think they’ve done a good job of that so far.”
The Rockies are treating this as a live test, not a finished product. Sunday was part of that research phase, and Sugano’s outing showed both the upside and the questions.
He was Colorado’s most consistent rotation arm this season, and he kept the Mariners to one hit. The lone damage came in the fourth, when Dominic Canzone singled in Randy Arozarena after Arozarena walked and moved up on the pitch.
Sugano mixed in off-speed stuff against Seattle and leaned away from his split-finger. He struck out five, walked two and exited after 72 pitches.
“To be honest with you, I wanted to go longer,” Sugano said through interpreter Yuto Sakurai. “I wasn’t aware that I was going up to five innings today, so it was a surprise to me. At minimum, I thought I could have gone seven, or gone to the mound for the seventh.”
That tension is part of what the Rockies are sorting through. With a new front office, new pitching-side coaching and a larger research and development department, the club has said it’s open to trying things. A formal piggyback plan is one of them.
The idea isn’t new in Denver. During part of the 2012 season, the Rockies tried a more structured paired-pitching approach under former general manager Dan O’Dowd and manager Jim Tracy, limiting four starters to 75 pitches with a scheduled reliever behind each one.
It never really took hold. Seattle also tried piggybacking earlier this season to work around unusual pitching depth, but communication issues got in the way.
Manager Warren Schaeffer was balancing the plan with the feel of the game, and the bullpen context mattered too. Colorado had leaned on relief arms heavily, including in Saturday night’s 5-3 win, when Jose Quintana was stretched to four innings in his first start back from a left elbow injury suffered May 24. Nick Frasso and Juan Mejia each threw two innings, and with closer Jordan Romano sick, Brennan Bernardino ended up working a rare third straight game.
Feltner’s own recent usage also fit into the conversation. He went four innings and allowed one unearned run in a 3-2 loss at Atlanta on Aug. 30, then fired five scoreless innings in relief of Kyle Freeland during Tuesday night’s 9-3 win over the Padres.
“[Feltner] is learning his body right now coming out of the bullpen,” Schaeffer said. “It’s a different feel for him, and he’s grinding for us.”
Even with the discomfort of pulling a starter who was rolling - “[Sugano] attacked the strike zone and he was ahead,” Schaeffer said - the pairing produced encouraging work, at least in the view of catcher Brett Sullivan.
“[Sugano] did an amazing job - he knew what he wanted to do before the game,” Sullivan said. “He wanted to land off-speed early, and when he did that and got ahead, it opened up everything for him.
The three times [Feltner] has come out of the bullpen, he’s been lights-out. He’s coming in and using his stuff right away, not trying to set up guys.”

Rockies Now Have Another Rotation Tension To Sort Out This Offseason
The Rockies latest loss of momentum has only sharpened the questions facing the club as the season winds down, and the rotation is now part of that broader offseason picture. Colorado is staring at a fourth straight 100-loss season, and with the 2026 campaign nearing its finish, the front office will soon be sorting through free agents, future roles and how much stability it can actually count on in the staff.
Tomoyuki Sugano added another wrinkle to that conversation after being lifted following five innings against the Mariners, a move he said left him surprised and frustrated because he believed he could have kept going. For a team already trying to separate short-term innings management from longer-term rotation plans, even one midgame decision can echo beyond a single start, especially when the organization is trying to decide what kind of pitching structure it wants to carry into next year.

Rockies Face An Emotional Coors Farewell With Rotation Jobs On The Line
The Rockies are closing out a season that has shown some improvement from 2025, even if the bigger picture still leaves them well out of playoff contention. Now the final homestand carries a little more weight than usual, with Kyle Freeland expected to take the mound in what could be his last start at Coors Field as the longest-tenured player on the roster and a pending free agent.
There is still evaluation to do beyond the emotion of Freelands possible farewell. Mason Adams and Tanner Gordon are lined up to start games in the final series, and both are trying to make a stronger case for themselves heading into next season, when every rotation spot and roster decision figures to be under a close watch.

Kyle Freeland Faces A Painful Rockies Possibility At Coors Field
Kyle Freeland is set to take the ball at Coors Field against the Diamondbacks with a familiar kind of pressure hanging over the outing. The left-hander is in the final season of his five-year contract, and his year has been shaped as much by health and inconsistency as by the usual demands of pitching in Denver. He is also coming back from a neck injury suffered in August, another reminder that nothing about this stretch has been easy.
The broader issue for the Rockies is even harder to ignore: they have to decide whether Freeland fits into next seasons plans. His 4-10 record and 6.38 ERA reflect how rough the year has been, and his $17 million player option will not vest because he has not reached the required workload. What happens next is the sort of call that can define an offseason for a club trying to sort out both its rotation and its direction. [Read more 🡒]
