Watch: Reds' Hamilton delivers walk-off HR off of Brewers' Hader

Hader's gonna hate.

Josh Hader entered Monday's contest against the Cincinnati Reds having allowed just two home runs over his first 32 2/3 career innings.

Meanwhile, since playing his first full season in 2014, Billy Hamilton has posted the eighth-lowest slugging percentage in all of baseball among qualified hitters.

Naturally, Hamilton's appointment with the Milwaukee Brewers reliever in the bottom of the ninth with two out went exactly as expected: The Reds center fielder went deep for his fourth home run of the year and first career walk-off dinger.
