Jansen was reinstated from the paternity list prior to Tuesday's game versus the Diamondbacks, Mike DiGiovanna of the Los Angeles Times reports.
The 33-year-old had been away from the team since Sunday and will return to his role as the closer for the Dodgers. Since July 24, he has converted all 11 of his save opportunities while posting a 1.29 ERA and 11.1 K/9 over 21 innings. Mitch White was optioned to Triple-A Oklahoma City in corresponding move.
