MLB Trade Rumors

This trade season, a number of controllable players were heavily rumored to be on the market who ultimately did not end up getting traded at all. Among that group, one of the most surprising players who wound up staying put with their current club was Pirates right-hander Mitch Keller. The Yankees, Red Sox, Blue Jays, Mets, and Cubs were all connected to Keller over the summer, and at one point a proper fire sale seemed to be on the table for Pittsburgh.

A deal didn’t come to pass with any of those clubs, however. Keller, Bryan Reynolds, and even pending free agents like Isiah Kiner-Falefa and Andrew Heaney were still in Pittsburgh come August 1. On some level, that seems to reflect the front office’s belief in the team as a potential short-term competitor, even in spite of its major flaws. GM Ben Cherington told reporters just recently that he believes the team can contend in 2026, so it stands to reason that a player like Oneil Cruz might not be on the market at this point, even if there were reasons to believe a team could’ve pried him away a few months ago.

That doesn’t necessarily mean room to make trades goes out the window, however. In that same conversation with reporters, Cherington acknowledged that upgrading the offense on the trade market was on the table for the Pirates heading into this winter. While Pittsburgh has one of the richest farm systems in the majors from which they could deal if so inclined, an organization that regularly runs some of the lowest payrolls in MLB may not want to part with packages rich with prospect capital to acquire just one or two hitters. That could make trading for the MLB roster an attractive alternative, and when looking at the players already in the majors it’s not hard to see why Keller in particular could be a piece it would make sense for Pittsburgh to part with.

While the right-hander looked quite good in the first half of the 2025 season, his numbers began to falter after the All-Star break. In his last 11 starts, he’s posted a 5.87 ERA and 5.21 FIP across 53 2/3 innings of work. Brutal as those numbers may be, when zooming out to look at his full-season stats, one sees that this tough stretch really only brought him back to what he’s established as his career norm at this point. For three seasons in a row now, Keller has made between 31 and 32 starts with an ERA between 4.20 and 4.25 with a FIP between 3.80 and 4.10. That’s remarkably consistent for a starting pitcher in today’s game. And while that works out to roughly league average production, average results with that volume and consistency are still valuable.

Valuable as Keller might be in theory, he’s not exactly a fit for the Pirates’ needs in practice. Paul Skenes offers plenty of consistency at the front of Pittsburgh’s rotation with much more impressive production. And while Keller is the only other established arm in the club’s starting five, a bevy of intriguing young arms like Jared Jones, Bubba Chandler, and Braxton Ashcraft appear poised to step into larger roles as soon as next year. With so many young players who have mid-rotation upside or better in the upper levels of the farm system starting to get their feet wet in the majors, perhaps sinking nearly $17MM in salary next year into a player who provides only average results doesn’t make much sense for a team that RosterResource suggests will finish 2025 with a payroll of less than $87MM.

That’s not to say he wouldn’t be valuable to other clubs, however. Keller’s contract is arguably slightly below market rate for a pitcher with his impressive consistency. Former Pirate Jameson Taillon received a four-year, $68MM contract from the Cubs during the 2022-23 offseason after two seasons as a Yankee with similar results to Keller’s recent work. And Yusei Kikuchi’s roughly league average work with the Mariners, Blue Jays, and Astros over the years earned him nearly $64MM over three years with the Angels just last offseason. By that metric, the just over $55MM Keller is owed over the next three seasons looks like something of a bargain for a large- or even mid-market club in need of rotation help, or it’s at least roughly market rate.

If the Pirates are able to work out a trade for a young, controllable hitter involving Keller and then reinvest Keller’s salary into position player talent, they could significantly retool their lineup by dealing the right-hander away. Of course, that course of action would risk the possibility that Keller puts it all together in the future and delivers a full season like his first half (3.48 ERA, 3.39 FIP) at some point after the trade, at which point the Pirates would have likely sold low on the righty. Keller won’t turn 30 until April of next year, so a step forward isn’t impossible to imagine even in spite of his year-to-year consistency. Trading Keller would also be a big gamble on the team’s young rotation talent, of whom only Skenes has proven himself truly reliable at this point. Perhaps that could be eased by signing another low-cost veteran like Heaney to offer some stability, but that would eat into the budget for improving the club’s offense.

How would MLBTR readers approach Keller this offseason, if they were in the Pirates’ shoes? Would they aggressively shop him for offense, or would they hold onto him for 2026 unless overwhelmed by an offer? Have your say in the poll below:
