The Mariners claimed right-hander Casey Sadler off waivers from the Cubs, according to an M’s press release. Chicago designated Sadler for assignment earlier this week.
Sadler had an impressive (if, according to advanced metrics, deceptive) 2.14 ERA over 46 1/3 combined innings with the Rays and Dodgers in 2019, and the Cubs acquired him in an January trade hoping the righty could emulate that performance. Instead, Sadler struggled with a 5.79 ERA over 9 1/3 innings for the North Siders, walking eight batters over that limited span of action.
Appearing in parts of five MLB seasons with the Cubs, Rays, Dodgers, and Pirates, Sadler has a career 3.82 ERA, 1.83 K/BB rate, 51.5% grounder rate, and 6.6 K/9 in 75 1/3 Major League innings. Originally a 25th-round pick for Pittsburgh in the 2010 draft, Sadler’s grounder-heavy approach has led to success at the minor league level, with a 3.43 ERA over 757 1/3 career frames on the farm.
Since Sadler is out of options, the Mariners won’t be able to send him to their alternate training site without exposing him against to the DFA wire. Given how the M’s are already looking ahead to 2021, there isn’t any harm in giving Sadler some innings to see if he could factor into next season’s plans, even if the 30-year-old isn’t a long-term piece.
