He will turn 37 next month but does not plan to retire.
Utley's club option was based on the number of days he was on the disabled list in 2015, and it came out to $11 million, according to multiple media reports.
The 38-year-old Arroyo, who was acquired from the Atlanta Braves at the trade deadline, did not pitch this season. The Dodgers will buy him out for $4.5 million instead of picking up his option for $11 million.
Peralta, 39, pitched only 29 innings and had a 4.34 ERA. The Dodgers did not pick up his $2.5 million option.
