Hendriks takes home the Mariano Rivera American League Reliever of the Year Award after saving 14 games in 24 appearances with a 1.78 ERA/1.14 FIP and 13.1 K/9 to 1.1 BB/9 across 25 1/3 innings. It was the second consecutive stellar campaign for the native Australian. He posted a 1.80 ERA/1.87 FIP in 75 games (85 innings) while notching 25 saves in 2019. In the postseason, he impressed with a scoreless 3-inning outing with the season on the line in Game 3 of the ALDS against Houston. Unfortunately, it ended up being his final appearance of the year, as Oakland would bow out of the postseason tourney in the next game.
Hendriks becomes the first A’s player to win the award, which replaced the Rolaids Relief Award in 2014. It’s particularly good timing for Hendriks, as the 2019 All-Star heads into free agency this winter at the pinnacle of his career.
Williams takes the Trevor Hoffman National League Reliever Of The Year Award from his teammate Josh Hader, who won the previous two seasons. It’s quite the achievement for the unheralded rookie, who rode his trademark change-up to a 0.33 ERA/0.86 FIP in 27 innings across 22 games with an absurd 17.7 K/9 to 3.0 BB/9 in 2020. The 26-year-old unfortunately missed the playoffs due to right shoulder soreness. He’ll be one of the more interesting cases to track next season, assuming a return to the standard 162-game season.
