The Athletics reassigned Hartlieb to minor-league camp Monday.

EDGE Analysis

Hartlieb had been attending big-league camp as a non-roster invitee, but any hope he had of being part of the Athletics' Opening Day bullpen ended after he allowed eight runs (seven earned) over 2.1 innings across four Cactus League appearances. The 32-year-old is likely to serve as organizational relief depth at the Triple-A level throughout the 2026 season.

The Athletics signed Hartlieb to a minor-league contract Wednesday.

EDGE Analysis

Hartlieb was torched for eight runs over 3.1 innings during his brief time in the majors in 2025, but he boasted a 62:17 K:BB over 53.1 frames at the Triple-A level. The right-handed reliever will likely begin the 2026 campaign in the bullpen at Triple-A Las Vegas.

Hartlieb signed a minor-league contract with the Royals on Wednesday.

EDGE Analysis

After being released from his minor-league deal with Detroit last week, Hartlieb quickly caught on with a new organization, his third stop of the season. Hartlieb previously made four appearances in the big leagues this season between the Yankees and Tigers, giving up eight earned runs over 3.1 innings.

The Tigers outrighted Hartlieb to Triple-A Toledo on Tuesday.

EDGE Analysis

Hartlieb had been removed from the Tigers 40-man roster and has passed through waivers. He has the ability to decline the outright assignment and elect free agency, but it's unclear if the reliever plans to do so.

The Tigers designated Hartlieb for assignment Saturday.

EDGE Analysis

After making two appearances with the Tigers and giving up two runs over two innings, Hartlieb will now be cast off the 40-man roster. Luke Jackson, who signed an MLB deal with Detroit on Saturday, will claim the open spot in the bullpen.

The Tigers selected Hartlieb's contract from Triple-A Toledo on Thursday.

EDGE Analysis

Hartlieb inked a minor-league contract with the Tigers earlier this month and is up with the big club after 2.1 perfect innings with four strikeouts at Toledo. The 31-year-old has managed just a 7.92 ERA over 66 career relief outings at the big-league level.

Hartlieb signed a minor-league contract with the Tigers on Saturday.

EDGE Analysis

Hartlieb made his organizational debut at Triple-A Toledo on Sunday, tossing 1.1 scoreless innings in a relief appearance. The 31-year-old righty had previously spent the entire 2025 season with the Yankees, making two appearances in the majors and 24 appearances at Triple-A Scranton/Wilkes-Barre.

Hartlieb elected free agency Friday.

EDGE Analysis

Hartlieb was designated for assignment Wednesday and will look for a new home after choosing free agency. The 31-year-old stumbled to a 40.50 ERA in two appearances with the Yankees this season, but he logged a much better 3.34 ERA in 35 innings at Triple-A Scranton/Wilkes-Barre.

The Yankees designated Hartlieb for assignment Wednesday.

EDGE Analysis

Hartlieb will give up his spot on the 40-man roster and 26-man active roster to right-hander Cam Schlittler, who was called up from Triple-A Scranton/Wilkes-Barre to start Wednesday's game against the Mariners. Hartlieb has made two appearances out of the Yankees bullpen this season, giving up six earned runs in 1.1 innings.

Hartlieb signed a major-league contract with the Yankees and was selected to the active roster Sunday.

EDGE Analysis

The right-hander elected free agency after being designated for assignment by the Yankees a few days ago, and he's quickly back on the MLB roster. Hartlieb allowed three earned runs over one inning during his lone appearance with New York and should fill a low-leverage relief role.
