Arroyo had received an invitation to big-league spring training and went 3-for-10 with a home run and five walks over six Cactus League games, but he hadn't appeared since being scratched from the lineup ahead of Friday's matchup with the Dodgers after experiencing neck spasms. The 21-year-old seems to have since moved past the issue, but with spring training winding down, Arroyo looks like he'll be in line for action on the back fields for the rest of camp. Arroyo is expected to open the season at Double-A Arkansas.

Arroyo was slated to start at second base and bat seventh in Friday's game before his injury flared up, and the Mariners should provide an update over the next couple of days once the 21-year-old undergoes further tests. Arroyo ended the 2025 season with Double-A Arkansas, where he slashed .255/.376/.341 with nine steals (on 12 attempts), two home runs and 15 RBI in 250 plate appearances.
