PEORIA, Ariz. (AP) — Seattle Mariners top prospect Jarred Kelenic will be sidelined due to a strained adductor muscle in his left knee.

Mariners general manager Jerry Dipoto said an MRI revealed the injury. 

No timeline was given for the outfielder's return. 

Kelenic appeared to be injured during his first at-bat on Friday against the Chicago White Sox. 

Kelenic reached on an error, but appeared bothered after reaching first base. 

Kelenic remained in the game and was replaced an inning later.
