The Red Sox have claimed right-handed reliever Geoff Hartlieb off waivers from the Mets and optioned him to Triple-A Worcester, the club announced earlier Saturday afternoon.
Hartlieb, 27, became available when he was designated for assignment by New York on Thursday so that the team could add fellow reliever Brad Hand to its 40-man and major-league roster.
In just three appearances with the Mets, Hartlieb allowed seven runs — all earned — on seven hits, six walks, and one hit batsman to go along with five strikeouts over 4 1/3 innings of work.
The right-hander began the 2021 season with the Pirates, posting a 7.71 ERA and 4.95 FIP in four outings (4 2/3 innings pitched) before being designated for assignment in early July.
A former 29th-round draft pick of Pittsburgh coming out of Lindenwood University (St. Charles, Mo.) in 2016, Hartlieb made his major-league debut for the Pirates in May 2019.
Since that time, the Illinois native has made a total of 57 appearances between the Pirates and Mets while also appearing in 45 games at the Triple-A level dating back to the start of the 2019 campaign.
While pitching at Triple-A across two separate seasons (2019, 2021), Hartlieb has put up a 3.18 ERA and strikeout-to-walk ratio of 77:28 over 62 1/3 total innings pitched.
Per Baseball Savant, the 6-foot-5, 240 pound righty operates with a three-pitch mix that consists of a slider, sinker, and four-seam fastball that has hovered around 93-94 mph season. He previously featured a changeup in 2019 and 2020, but apparently has not done so this year.
Hartlieb, who turns 28 in December, will join a WooSox bullpen that includes a number of relievers with big-league experience, such as Eduard Bazardo, Brandon Brennan, Colten Brewer, Austin Brice, Alex Claudio, Michael Feliz, Kyle Hart, and Yacksel Rios, among others.
It is also worth mentioning that Hartlieb has two minor-league option years remaining and is not arbitration eligible until 2023, so something to keep in mind there.
Additionally, the Red Sox did not need to make a corresponding move to add Hartlieb to their 40-man roster on account of the nine players they have on the COVID-19 related injured list.
