The Philadelphia Phillies made a series of roster moves ahead of Saturday night’s showdown against the New York Yankees, bolstering both their outfield depth and pitching staff as the front office continues to reshape the roster before the MLB trade deadline.
In a busy day of transactions, the Phillies acquired outfielder Kameron Misner from the Kansas City Royals, promoted right-hander Brian Keller for his long-awaited Major League debut, recalled left-handed reliever Kyle Backhus, and made several corresponding roster moves in an effort to strengthen a team firmly in the postseason race.
Phillies Add Former First-Round Pick to Outfield Depth
The day’s first transaction saw Philadelphia acquire Kameron Misner from the Royals in exchange for cash considerations.
Although Misner was immediately optioned to Triple-A Lehigh Valley, the move gives the Phillies another athletic outfielder with intriguing upside and valuable organizational depth. To make room for him on the 40-man roster, the club designated outfielder Steward Berroa for assignment.
Misner has been one of the top performers at the Triple-A level this season. In 63 games with Omaha, he posted an outstanding .941 OPS while launching 14 home runs and stealing 14 bases, showcasing the combination of power and speed that has long made him an intriguing prospect.
Across seven minor league seasons, the 28-year-old has accumulated 90 home runs and 143 stolen bases, proving he possesses an impressive all-around offensive skill set.
However, that production has yet to translate consistently in the Major Leagues.
Over parts of three seasons with the Tampa Bay Rays and Kansas City Royals, Misner has appeared in 97 MLB games, batting .206 with five home runs and a .571 OPS.
Despite those struggles, Phillies interim manager Don Mattingly remains optimistic about the left-handed hitter’s potential.
Mattingly previously managed Misner during his time with the Miami Marlins organization after the outfielder was selected in the first round of the 2019 MLB Draft.
“He’s a big, physical kid who can run, play all three outfield positions, and has legitimate power,” Mattingly said. “He’s had much more success in Triple-A than the big leagues so far, but we know the tools are there.”
While Philadelphia’s biggest offensive need remains adding a right-handed bat capable of producing against left-handed pitching, Misner provides valuable depth and defensive versatility as the club continues exploring additional trade possibilities.
Brian Keller Finally Gets His MLB Opportunity
Among Saturday’s roster moves, perhaps the most inspiring belonged to veteran right-hander Brian Keller.
The Phillies selected Keller’s contract from Triple-A, giving the 32-year-old his first opportunity to pitch in the Major Leagues after years of perseverance.
Keller was scheduled to work behind left-handed opener Tim Mayza against the Yankees, serving as the club’s bulk pitcher.
His promotion comes after an outstanding season with Lehigh Valley, where he posted a stellar 2.23 ERA across eight starts while consistently giving the IronPigs quality innings.
The call-up represents the culmination of a remarkable comeback story.
After pitching professionally in Japan during the 2023 season, Keller suffered an elbow injury just three appearances into his overseas stint. The injury ultimately required Tommy John surgery, forcing him to miss the entire 2024 and 2025 seasons.
Now fully healthy, the veteran has worked his way back to earn the first Major League opportunity of his career.
Phillies Reinforce Left-Handed Relief Corps
Philadelphia also strengthened its bullpen by recalling left-hander Kyle Backhus from Triple-A Lehigh Valley.
Backhus made 17 appearances for the Phillies earlier this season before being optioned after posting a 5.87 ERA. Despite the inconsistent results, the organization believes he can provide valuable depth from the left side.
His return is particularly important because the Phillies have struggled to find consistent production from their left-handed relievers throughout the season.
With Tim Mayza opening Saturday’s game, José Alvarado would have been the only other available left-handed reliever had Backhus not been recalled.
Mattingly emphasized the importance of carrying multiple lefties, especially against a dangerous lineup like New York’s.
Having another southpaw available allows Philadelphia to create more favorable pitching matchups late in games and provides insurance if Alvarado has already been heavily used.
Young Pitchers Sent Back to Triple-A
To create room on the active roster for Keller and Backhus, the Phillies optioned right-handers Max Lazar and Alex McFarlane to Triple-A.
McFarlane, ranked as Philadelphia’s No. 19 prospect, had just made his Major League debut earlier in the week, tossing a scoreless inning before returning to Lehigh Valley for additional development.
The move reflects the organization’s desire to maintain pitching depth while ensuring its young arms continue receiving regular opportunities to develop.
Phillies Continue Preparing for Trade Deadline
Saturday’s roster shuffle may only be the beginning of Philadelphia’s activity.
With the trade deadline approaching, the Phillies remain focused on adding impact talent to strengthen both their lineup and pitching staff for the playoff race.
The acquisition of Misner improves organizational depth, while the promotions of Keller and Backhus provide immediate help for a pitching staff looking for consistency.
As Philadelphia continues its push toward October, every roster move carries increased significance, and the front office appears determined to leave no area of the club unaddressed.
