Utley, 39, batted .236 with 8 home runs and 34 RBIs in 127 games in 2017 with Los Angeles.

Utley's team ethic and personal investment give him leverage when necessary. He's manager Dave Roberts' favorite conduit to convey the subtle reminders that keep a clubhouse running smoothly through a long, stressful summer.
