The Red Sox lost two players on waivers to two different teams on Saturday. Recently designted outfielder Jeisson Rosario was claimed by the division rival Yankees, while recently designated right-hander Kyle Tyler was claimed by the Padres.
Rosario, 22, was one of two players the Sox acquired from the Padres in the August 2020 trade that sent veteran first baseman Mitch Moreland to San Diego. Hudson Potts, the other prospect Boston got in that deal, was designated for assignment himself on Monday but cleared waivers and remains in the organization.
After being added to the Red Sox’ 40-man roster in November 2020 to receive protection from the Rule 5 Draft, Rosario came into the 2021 season regarded by Baseball America as the No. 21 prospect in Boston’s farm system. The speedy left-handed hitter spent the entirety of the year with Double-A Portland and slashed an underwhelming .232/.335/.307 with three home runs, 36 RBIs, 48 runs scored, and 11 stolen bases over 98 games spanning 405 plate appearances.
On the heels of such a disappointing season, Rosario was clearly on the bubble coming into major-league camp this spring. He officially lost his spot on the Sox’ 40-man roster when the club signed announced their signing of free-agent infielder Trevor Story.
Tyler, on the other hand, had a much briefer stay with the Red Sox. The 25-year-old right-hander was claimed off waivers from the Angels on Tuesday but was then designated for assignment on Thursday when fellow righty Ralph Garza was claimed off waivers from the Twins.
A former 20th-round draft pick of the Halos out of the University of Oklahoma, Tyler debuted for Los Angeles last September and posted a 2.92 ERA and 5.20 FIP to go along with six strikeouts and six walks across five appearances (12 1/3 innings pitched) out of the bullpen.
In the wake of these moves being made, the Red Sox’ 40-man roster remains at full capacity. They also have 56 players on their spring training roster with less than two weeks until Opening Day.
