The Rangers transferred Seager (hernia) to the 60-day injured list Friday.
Seager is slated to undergo season-ending surgery Friday to address his sports hernia, and his move to the 60-day IL will officially rule him out for the remainder of the season. Jacob deGrom (elbow) will return from the IL to fill the open 40-man spot. Seager is expected to be fully recovered by spring training.
