Jeisson In his first summer as a pro, Rosario headed straight to the Arizona complex and began making an impression and turning heads with his agility and approach at the bat.

As an 18-year-old in 2018, he made his full-season debut in A-Ball, and he was able to play all of 2019 at High-A before turning 20.

Before the move, he spent last season at the Padres Alternate Site, then finished up in Pawtucket before being added to the 40-man roster this offseason to keep him out of the Rule 5 Draft.

At the 2020 trade deadline, the Red Sox acquired Rosario and Hudson Potts from the San Diego Padres in exchange for first baseman Mitch Moreland.

Rosario had progressed from a 19-year-old continuing his journey up the minor league system in Southern California (High-A Lake Elsinore Storm) to a 21-year-old with the Double-A Sea Dogs in Portland, Maine, by the time true competitive action resumed.

Rosario’s power is practically non-existent (he’s never hit more than three home runs at any level), but his plate discipline has been one of the reasons he’s kept on the prospect radar throughout the years.

Because of a 16.6% walk rate and a 21.7 percent strikeout rate, his.242 average in High-A in 2019 looks a lot better when paired with a.372 OBP.
