He has posted a 0.82 WHIP and opposing batters are hitting just .207 with a .283 slugging percentage (1 double, 2 home runs) against him.
A two-time American League All-Star (2015, 2016) and member of the 2015 World Series Champion Kansas City Royals, Herrera entered Monday ranked among American League relievers in WHIP (2nd, 0.82), ERA (1st, 1.05), opp. OBP (2nd, .223), walks per 9.0 IP (2nd, 0.70), strikeout-to-walk ratio (5th, 11.00) and saves (T8th, 14).

His 22 strikeouts were the second-highest by a relief pitcher in Postseason history, trailing only Francisco Rodriguez, who struck out 28 batters in 2002.
In eight Major League seasons, Herrera is 23-27 with 57 saves and a 2.75 ERA in 442 games out of Kansas City’s bullpen. He ranked eighth in the American League with a career-high 26 saves in 2017.
