Casey Sadler Announces Retirement

Right-hander Casey Sadler announced his retirement from baseball today on X. In his statement, he thanks many people, including baseball fans, young players, his parents, his coaches and his agent.

Sadler, now 34, was selected by the Pirates in the 25th round of the 2010 draft out of Western Oklahoma State College. He worked his way up the minor league ladder, mostly as a starter, getting some brief big league looks in 2014 and 2015. Unfortunately, he required Tommy John surgery in October of 2015 and had to miss the entire 2016 season. In 2017 and 2018, he was back on the hill and pitching in relief a bit more but mostly in the minors, only getting into two big league games in 2018.

He was no longer on Pittsburgh’s roster at the end of 2018 and was able to become a free agent. He ended up having a bit of a breakout in 2019, split between the Rays and Dodgers. He signed a minor league deal with Tampa for that year and eventually tossed 19 1/3 innings for them, with a 1.86 earned run average. He was designated for assignment and flipped to the Dodgers in July, then posting a 2.33 ERA in 27 innings for his new club after the swap. He finished the year with a combined 46 1/3 innings with a 2.14 ERA. His 16% strikeout rate was subpar but he limited walks to a 6.7% clip and got grounders on 51.8% of balls in play.

In 2020, he wasn’t able to build off that performance in the pandemic-shortened season. He was flipped to the Cubs and later to the Mariners, finishing the year with a 5.12 ERA in 19 1/3 innings. His strikeout rate jumped to 24.4% but he also gave free passes to 14% of opponents.

But an even better breakout than 2019 followed in 2021. He tossed 40 1/3 innings for the Mariners that year with a miniscule ERA of 0.67. He had a 25.5% strikeout rate, 6.9% walk rate and 62.9% ground ball rate. He moved up the bullpen pecking order, eventually earning 15 holds that year.

Unfortunately, he was never able to build on that incredible campaign. He and the M’s avoided arbitration by agreeing to a $1.025MM salary for 2022 but Sadler required season-ending surgery in March, before the campaign even began. He spent the entire season on the injured list and was outrighted off the roster in November. He re-signed with the Mariners on a minor league deal for 2023 but spent much of that year on the minor league injured list and struggled when on the mound.

Per Sadler’s retirement announcement, he recently thought he would require another Tommy John surgery but then found out the problem was mental. His wife had started a pitching lesson business, which she asked him to get involved in. Sadler says that working with the younger pitchers gave him a renewed sense of purpose and improved his mental health, but also reduced his own desire to play.

Injuries prevented him from being on the big stage for long, but he performed exceptionally well when under the lights. Sadler retires with 101 major league games under his belt and a 2.86 ERA in that time. He struck out 104 opponents, recording one save, 22 holds and six wins. We at MLBTR congratulate him on a fine career and wish him the best in all his future endeavors.
