Jankowski was designated for assignment by the Dodgers on Saturday.
The club chose to cast Jankowski off the 40-man roster due to the promotion of right-hander Wilmer Font from Triple-A Oklahoma City. Jankowski was recently DFA'd by the Astros in mid-August, and has spent the last couple weeks with Oklahoma City, tossing three scoreless innings for the club. If he passes through waivers unclaimed, he will remain in Oklahoma City.
