The Orioles have reunited with Zach Eflin, as USA Today’s Bob Nightengale reports that Baltimore has signed the right-hander to a one-year free agent deal. The New York Post’s Jon Heyman reports that Eflin will earn $10MM, and Andy Kostka of the Baltimore Banner adds that the contract contains a mutual option for 2027. Eflin is represented by O’Connell Sports Management.
The $10MM guarantee breaks down as a $5MM salary, a $3MM signing bonus, and then a $2MM buyout on the mutual option, according to FanSided’s Robert Murray. As a reminder, mutual options are virtually never exercised by both parties, so Eflin’s deal is for all intents and purposes just a one-year pact. There is some significant bonus money involved, as both Eflin’s buyout and option will increase by $1MM if he makes at least 15 starts, then by $1.5MM if he makes at 20 starts, and one final increase of $2.5MM if he hits the 25-start threshold. The mutual option’s buyout can therefore max out at $7MM.
The O’s have been linked to several top-tier free agent pitchers this winter, and they also just swung a notable trade to land a hurler with frontline potential in Shane Baz. The 32-year-old Eflin is more of a depth signing for the back of the rotation, and perhaps something of a flier given his uncertain health situation. Eflin underwent a back surgery in August that came with a rather broad recovery timeline of 4-8 months, so the fact that he has now signed a contract after four months perhaps hints that his rehab is going quite smoothly.
It would be a welcome relief for both Eflin and the Orioles if he is able to pitch normally during Spring Training and be available for the Opening Day roster. Assuming Eflin is ready to go by March 26, he’ll slot in as the fourth or fifth starter in a projected rotation that includes Trevor Rogers, Kyle Bradish, Baz, and Dean Kremer. Tyler Wells had a line on a rotation spot but could take on a bullpen or a swingman role. Albert Suarez is another swingman candidate, plus Cade Povich, Chayce McDermott, and Brandon Young are further rotation depth options in the upper minors.
If Baltimore still wanted to make a splash by signing or trading for more of a proven ace, the Eflin signing likely isn’t an obstacle. Given how many injuries the Orioles rotation suffered in 2025, it is no surprise that the team wants as much depth as possible to both cover innings and deliver quality results going forward.
Eflin’s own injury woes contributed to the Orioles’ health problems, as lat and back injuries resulted in three separate stints on the injured list for the righty last year. Eflin was limited to just 71 1/3 innings over 14 starts, and he struggled to a 5.93 ERA and a 16.2% strikeout rate. The righty’s 4.2% walk rate was still excellent, however, and since a lot of the damage off Eflin came via a spike in his homer rate, his 4.49 SIERA was more respectable than his real-world ERA.
This isn’t the first time Eflin was plagued by injuries, as persistent knee issues bothered the right-hander earlier in his career with the Phillies.
