The Red Sox have promoted pitching prospect Tyler Uberstine from Low-A Salem to High-A Greenville, per the team’s minor-league transactions log.
Uberstine, 23, is currently regarded by SoxProspects.com as the No. 38 prospect in Boston’s farm system, ranking 16th among pitchers in the organization. The Red Sox originally selected the right-hander in the 19th round of last year’s draft out of Northwestern University and signed him for $97,500.
After pitching in the MLB Draft League and rookie-level Florida Complex League last summer, Uberstine began his first full season in pro ball with Salem. In 14 starts (eight appearances) for the Red Sox, the California native posted a 4.63 ERA — but much more respectable 3.87 FIP — to go along with 66 strikeouts to 21 walks over 58 1/3 innings of work.
Among Carolina League pitchers who have thrown at least 50 innings to this point in the season, Ubserstine ranks 18th in strikeouts per nine innings (10.18), 14th in walks per nine innings (3.24), 15th in walk rate (8.4%), 18th in swinging strike rate (14%), 12th in groundball rate (49.1%), 16th in FIP, and eighth in xFIP (3.53), per FanGraphs.
Listed at 6-foot-1 and 200 pounds, Uberstine throws from a three-quarters arm slot and works with a three-pitch mix that consists of a 91-93 mph fastball that tops out at 95 mph, a changeup, and a slider, according to his SoxProspects.com scouting report.
Uberstine becomes the latest member of Boston’s 2021 draft class to get called up to Greenville, joining the likes of Wyatt Olds, Jacob Webb, Nathan Hickey, Niko Kavadas, Tyler McDonough, and Phillip Sikes.
In order to make room on the roster for Uberstine, the Drive transferred fellow righty Chih-Jung Liu to the development list.
