Jansen struck out two in a perfect ninth inning Tuesday to record his fifth save of the season in a 3-1 win over the Cubs.
The veteran closer had a shaky first appearance for Atlanta, but since then Jansen has delivered six straight scoreless outings with a 9:0 K:BB and five straight save conversions. The 34-year-old's 3.86 ERA looks out of place next to his 0.71 WHIP, 38.5 percent strikeout rate and 1.08 FIP.
