In 2017 he was traded to the Oakland Athletics, where his career reached new heights. In 2018 he enjoyed a truly dominant season as the Athletics’ closer, posting outstanding numbers with a minuscule earned run average and a large number of saves, earning his first All-Star selection and establishing himself as one of the best relievers in all of baseball.
Blake Treinen with the Dodgers
Blake Treinen joined the Los Angeles Dodgers in 2020, and he became a crucial part of the team’s elite, championship-calibre bullpen. That first season with the Dodgers ended in triumph, as the team won the World Series and he earned his first championship ring. After a brief spell with another organisation, he returned to the Dodgers, and he continued to serve as a trusted high-leverage reliever, overcoming injuries at times to remain a key contributor. His steady, reliable presence made him a valued veteran leader in the Dodgers’ pitching staff.
