Jansen notched the save after allowing one run on one hit and two walks while striking out one in the ninth inning Friday night against the Nationals.
Jansen entered the ballgame in the ninth with a three-run lead, and he would walk in a run before retiring the final batter of the night via strikeout. Things haven't always been easy for the 31-year-old closer this season, though he has converted 25 of 29 save opportunities. Jansen owns a 3.67 ERA and 1.06 WHIP with a 57:11 K:BB over 41.2 frames this season.
