Kyle Backhus

Kyle Backhus

28-Year-Old PitcherRP
Philadelphia Phillies AAA
2026 Fantasy Outlook
Backhus is a sidearming lefty reliever who held left-handed hitters to just a .139/.225/.278 slash line in 2025. Righty bats slashed .365/.417/.571 off the 27-year-old, so he'll likely have a limited middle relief role with the Phillies who acquired him from the Diamondbacks in the offseason. Read Past Outlooks
Signed a one-year contract with the Phillies in March of 2026.
Demoted to Triple-A
PPhiladelphia Phillies  AAA
July 7, 2026
The Phillies optioned Backhus to Triple-A Lehigh Valley on Tuesday.
Analysis
Backhus pitched each of the last two days, so the Phillies will replace him with a fresh bullpen arm. It will be Max Lazar taking Backhus' spot on the roster.
