The Washington Nationals placed left fielder Juan Soto on the 10-day injured list Saturday because of back spasms, according to The Athletic's Brittany Ghiroli.
The move is retroactive to Wednesday. The team recalled outfielder Andrew Stevenson in a corresponding roster move.
Soto made an instant splash as a 19-year-old rookie when he was called up during the 2018 campaign, drilling home runs and hitting at a head-turning rate out of the gate. In all, he slashed .292/.406/.517 with 22 home runs and 70 RBI in his rookie campaign after playing his way into the team's rotation.
