Prior to today’s game with the Rangers, the Marlins selected Geoff Hartlieb’s contract from Triple-A Jacksonville. Left-hander Ryan Weathers was optioned to Triple-A in the corresponding transaction.
The move brings a fresh arm into Miami’s bullpen, as Weathers threw 3 2/3 innings of relief on Saturday and was hit hard, allowing six earned runs against the powerful Texas lineup. It is possible Hartlieb’s stint in the majors lasts for only a day until the Marlins need a roster spot to bring Eury Perez back to the Show, but Hartlieb pitched an inning against the Rangers, marking his first MLB appearance since 2021.
Hartlieb signed a minor league deal with Miami during the winter and has spent the entire season in Jacksonville, though injuries kept him on the shelf until May. This late start might’ve cost the right-hander an earlier look on the big league roster, as Hartlieb has a 3.18 ERA over 34 relief innings and some solid peripherals (25.5% strikeout rate, 9.2% walk rate, 47.2% grounder rate).
A 29th-rounder for Pittsburgh in the 2016 draft, Hartlieb tossed 66 1/3 innings over 57 games with the Pirates and Mets from 2019-2021, posting a 7.46 ERA. The Red Sox acquired him via waiver claim in September 2021 but he didn’t receive any Major League action in over a year in the organization, as Hartlieb had a 5.16 ERA over 61 innings for Boston’s Triple-A affiliate in 2022.
