Red Sox pitching prospect Oddanier Mosqueda made his Grapefruit League debut in Thursday’s 4-3 win over the Twins at JetBlue Park.
The left-hander came on in relief of Michael Wacha in the fifth inning and struck out three of the six batters he faced while working in and out of a bases-loaded jam.
Mosqueda, 22, was originally signed by the Sox as an international free agent out of Venezuela in 2015. The Caracas native made his professional debut in the Dominican Summer League and progressed as far as Low-A before the COVID-19 pandemic wiped out the 2020 minor-league season.
After making 10 appearances for Caribes de Anzoategui of the Venezuelan Winter League that off-season, Mosqueda came into 2021 and broke minor-league camp with High-A Greenville.
Spending the entirety of the 2021 campaign with the Drive, Mosqueda posted a 3.61 ERA and 3.43 FIP to go along with 66 strikeouts to 25 walks over 32 relief appearances spanning 47 1/3 innings of work. He spent some time away from the team in late May/early June to pitch for Venezuela in the 2021 Americas Olympic Qualifier.
As of August 10 of last year, Mosqueda’s ERA on the season stood at 5.29. From that point forward, though, the lefty strung together 10 consecutive scoreless outings (15 innings) in which he struck out 21 and walked just four to end his season on a high note.
Among all High-A East pitchers who accrued at least 40 innings on the mound in 2021, Mosqueda ranked 20th in strikeouts per nine innings (12.55), 13th in strikeout rate (33.8%), ninth in batting average against (.182), and 13th in FIP, per FanGraphs.
While his strikeout numbers are undoubtedly impressive, Mosqueda also struggled with his command at times and gave up his fair share of walks as a result. The fact he averaged 4.75 walks per nine innings and walked nearly 13% of the batters he faced last year speaks to this.
At the conclusion of the 2021 minor-league season, Mosqueda returned to his home country to suit up for Caribes de Anzoategui once more, though he struggled to the tune of a 11.05 ERA in 11 outings (7 1/3 innings pitched) with the club.
Listed at 5-foot-10 and 190 pounds, Mosqueda operates with a three-pitch mix that consists of a 92-94 mph fastball, a 79-81 mph curveball, and an 83-84 mph changeup, per his SoxProspects.com scouting report.
Mosqueda, who turns 23 in May, is not regarded by any major publication as one of the top prospects in Boston’s farm system coming into the 2022 season, including SoxProspects.com.
That being said, the Venezuelan-born southpaw is projected by the site to begin the year with Double-A Portland. Should Mosqueda prove capable of handling a more advanced level of competition, he has the chance rise through the organization’s relief prospect ranks.
