He’s Wilyer Abreu, who came over from the Houston Astros along with Enmanuel Valdez in last season’s Christian Vázquez trade. He’ll be making his Major League debut with the Red Sox in the coming days, as he’s been called up to replace Jarren Duran, who was just placed on the IL with a sore toe.
What position does he play?
He’s exclusively an outfielder, though it’s not yet clear what his best outfield spot is; he’s played 35 games in left this year, 27 in right, and 18 in center. He has a very strong arm and is a good athlete (he stole 31 bags in AA last year), so there’s hope that he can play at least adequate defense in Fenway’s massive right field (if not above average defense), while also serving as a backup center fielder.
