The Guardians recalled Peterson from Triple-A Columbus on Sunday, Roundtable.io reports.
Craig Yoho was demoted after allowing two runs in just one-third of an inning Saturday, and it will be Peterson who takes the open spot in the Cleveland bullpen. Peterson has made just one appearance for the Guardians to date, tossing two scoreless innings with three strikeouts against Detroit in his major-league debut back on Sept. 5. The right-hander turned in a 4.41 ERA, 1.41 WHIP and 107:38 K:BB over 102 innings with Columbus this season.

Cleveland optioned Peterson to Triple-A Columbus on Sunday, Tim Stebbins of MLB.com reports.
Peterson had been called up Friday and pitched two scoreless innings with three strikeouts in his major-league debut Saturday. Despite that impressive performance, the righty reliever is headed back to Triple-A to make room in the Guardians bullpen for a fresh arm in Franco Aleman, who was recalled in a corresponding move.

The Guardians recalled Peterson from Triple-A Columbus on Friday, Tim Stebbins of MLB.com reports.
Peterson was added to the Guardians' 40-man roster last offseason, but this will be his first stint in the big leagues. The 26-year-old has logged a 4.53 ERA and 102:34 K:BB across 95.1 frames this season with Columbus. Peterson will likely be needed to cover some innings during Friday's doubleheader versus the Tigers.

Peterson (triceps) has made two starts for Triple-A Columbus since being activated from the 7-day injured list Tuesday, covering seven innings and striking out six batters while yielding one earned run on four hits and one walk.
Peterson was shelved to begin the season after being diagnosed in late February with a right triceps strain, but he appears to have made a seamless recovery from the injury and was able to join the Columbus rotation last week without requiring a rehab assignment. The Guardians added the 26-year-old righty to their 40-man roster over the winter, but he remains somewhat buried on the organizational depth chart and may need the Cleveland rotation to lose multiple key arms before getting the chance to make his MLB debut.

The Guardians optioned Peterson (triceps) to minor-league camp Friday.
Peterson suffered a right triceps strain in late February and will not be ready for the start of the season. Once healthy, he'll be ticketed for the rotation at Triple-A Columbus.

Peterson was diagnosed with a right triceps strain Saturday and will require roughly 6-to-8 weeks of recovery time, Tim Stebbins of MLB.com reports.
Peterson suffered the injury during his appearance in Tuesday's Cactus League game against the Dodgers. He won't be able to make another appearance this spring and will almost certainly begin the regular season on either the Guardians' injured list or Triple-A Columbus' IL.
