Jansen allowed one run and struck out one batter in one inning during Friday's 9-6 win over the Mets.
Jansen made his first appearance of the month and coughed up a solo shot to Jeff McNeil. The veteran closer hasn't earned a save since July 29 and he saw his ERA climb to 3.57 through 40 appearances. As expected, Jansen is still the team's top closing option, with the newly acquired Raisel Iglesias working the eighth inning Friday.
