RHP: Greg Holland, Rockies (28 Sv, 1.39 ERA, 2.29 FIP, 12.0 K/9, 2.1 WAR)
RHP Wade Davis, Cubs (16 Sv, 1.86 ERA, 1.95 FIP, 13.0 K/9, 0.9 WAR)
RHP: Corey Knebel, Brewers (13 Sv, 1.11 ERA, 2.00 FIP, 15.7 K/9, 2.3 WAR)
Jansen has put up unearthly numbers this year, striking out 51 of the first 112 hitters he faced before issuing a walk, that in his 33rd inning of work. He's converted all 20 of his save chances, nine of which have been for four outs or more. Holland has returned to elite status after missing all of last season due to Tommy John surgery and has blown just one save this year. Davis has given the Cubs something they lacked for the first two-thirds of last season, a lights-out closer, and while the opportunities haven't been abundant during their season-long slump, he's converted every one he's gotten and is now in his fourth straight season with an ERA of 1.87 or lower. Knebel didn't take over closer duties until mid-May, but he's dominated all season, and is the only NL reliever striking out a higher percentage of hitters than Jansen (43.3% to 43.1%).
