Phillies outright Brian Keller after he clears waivers
The 32-year-old right-hander stays in the organization but comes off the 40-man roster, per the club's announcement, and could reach minor-league free agency this winter.

The Phillies announced that right-hander Brian Keller cleared waivers and has been outrighted to the minors, removing him from the 40-man roster while keeping him in the organization. Per FanSided's Robert Murray, the club had designated Keller for assignment on August 19 to create the necessary roster spot for their agreement with left-hander Nestor Cortes Jr. The outright assignment means Keller could reach minor-league free agency this offseason unless Philadelphia adds him back to the 40-man roster before then.
What happened
The Phillies placed Keller on outright waivers following the designation for assignment, and no other club claimed him during the 48-hour window. The announcement came two days after the initial roster move. Keller remains Phillies property and can continue pitching in the minor-league system, but he no longer occupies one of the 40 spots reserved for players eligible for immediate major-league recall.
The sequence is a familiar one in late August, when clubs balance the immediate roster against the winter's Rule 5 draft exposure and the September expansion that arrives in nine days. Keller's removal opened the spot that allowed the Phillies to finalize the Cortes transaction, which Murray reported at the time of the designation.
Why it matters
An outright assignment is the administrative outcome when a player clears waivers after a designation for assignment. The player stays under contract but loses his 40-man roster protection, which means he cannot be called up to the majors unless the club first adds him back to the 40-man—a move that would require another corresponding transaction. For a 32-year-old depth arm on a contending club in late August, the outright is effectively a return to organizational depth status, with the added wrinkle that he could become a free agent this winter if the Phillies do not restore his roster spot.
The timing matters because Keller's departure cleared the way for Cortes, a left-hander with a longer major-league track record. The Phillies are 80-63, second in the National League East and five games behind the division leader, and they hold the second Wild Card spot with a margin above the cut line. The club is one loss into a new streak after a long summer of jockeying for playoff position, and the rotation and bullpen depth that carries a team through September is now being assembled in real time.
Keller's brief major-league tenure—a single appearance on July 25 against the Yankees—was the kind of spot start that fills a schedule gap but does not establish a roster claim. He worked three innings behind an opener, allowed a home run to Austin Wells, and otherwise kept the game clean. The Phillies optioned him a few days later, and he returned to the minors until the designation for assignment arrived three weeks after that.
The backstory
Philadelphia signed Keller to a minor-league contract in May, a low-risk addition of the sort that populates minor-league rosters across the sport. The University of Wisconsin-Milwaukee product had not pitched in affiliated baseball in four years. Per Murray's report, Keller had intended to pitch in Japan during the intervening seasons but essentially lost those years to circumstances not detailed in the announcement.
The gap between affiliated appearances is not unusual for organizational depth arms, who often cycle through independent leagues, foreign circuits, and minor-league deals in search of the next opportunity. Keller's path back to the majors took him through the Phillies' system this summer, and his July call-up represented the kind of reward that makes the minor-league grind worthwhile, even if the stay was brief.
Now 32, Keller could head into the offseason as a minor-league free agent unless the Phillies find a reason to restore his 40-man status before the winter. That outcome is possible but not common for a pitcher with one major-league appearance and no clear role on a contending roster. The outright assignment keeps him in the organization for the remainder of the season, but the winter will bring a fresh round of decisions for both sides.
Where the club stands
The Phillies are 80-63 and sit second in the National League East, five games behind the division leader. They hold the second Wild Card spot with a +4.5 relative to the cut line, a comfortable margin but not one that invites complacency with five weeks remaining in the regular season. The club has lost its last game and will look to Andrew Painter on Saturday when the St. Louis Cardinals visit Citizens Bank Park. Cristopher Sánchez is scheduled for Sunday's series finale, and Zack Wheeler will take the mound Monday when the Phillies open a road series in Seattle against the Mariners.
The rotation depth that Keller briefly supplemented in July is now being reinforced by the addition of Cortes, whose agreement required the 40-man roster spot that Keller's designation for assignment created. The Phillies are navigating the final stretch of the season with an eye on both the division race and the Wild Card cushion, and the roster churn of late August reflects the urgency of a club that expects to play deep into October.
What we don't know yet
The Phillies have not announced the details of the Cortes agreement, and it remains unclear when the left-hander will join the active roster or what role he will fill. The club also has not specified where Keller will pitch in the minors for the remainder of the season, though a minor-league affiliate is the most likely destination for a pitcher with recent major-league experience.
Keller's winter plans are also uncertain. He could reach minor-league free agency unless the Phillies add him back to the 40-man roster, a move that would require another corresponding transaction and a clear organizational need. The club could also re-sign him to a new minor-league deal, a common outcome for depth arms who clear waivers and remain in good standing with the front office.
What to watch
The Phillies will finalize the Cortes transaction in the coming days, and the left-hander's first appearance—whether as a starter, bulk reliever, or long man—will clarify the role the club envisions for him down the stretch. The rotation picture will also come into focus as September approaches and the active roster expands to 28 players, a change that allows contending clubs to carry extra pitching depth without sacrificing bench flexibility.
Keller's immediate future is in the minors, where he will continue to build innings and remain available if the Phillies need emergency depth in September. His longer-term future will be decided this winter, when he could become a free agent and field offers from other organizations or negotiate a return to Philadelphia on a new minor-league deal. For now, he remains in the organization, off the 40-man roster, and one of the many depth arms who populate the back pages of the transaction wire in late August.
