The Tigers continued paring down their roster on Friday, outrighting left-hander Kyle Ryan, right-hander Myles Jaye, catcher Bryan Holaday and first baseman Efren Navarro to the Minor Leagues.
In a roster formality, designated hitter Victor Martinez was reinstated from the 60-day disabled list.
The moves leave the Tigers with 31 players on their 40-man roster heading into the offseason.
All four players who were outrighted can become free agents next week, either by declining an assignment or as six-year Minor League free agents.
Of the four, only Holaday was eligible for arbitration. He was added to the Tigers’ 40-man roster as a September call-up for catching depth after spending the summer at Triple-A Toledo.
