Sawamura has a fastball that he throws in the high 90s and a split-finger fastball that he throws 90 mph.
Earlier in his career, he was mostly a starter before transitioning to the bullpen. In 2015 and 2016, he was the Giants' primary closer, saving 73 games between the two seasons. More recently, he worked in more of a high-leverage set-up capacity -- the same role the Sox foresee for him.
