2022 Player Outlook
Whitlock was a dominant force working out of the Red Sox’s bullpen. Opposing batters couldn’t catch up to his fastball (.059 BAA), and his changeup (.161 BAA) and slider (.200 BAA) were extremely effective as well. One area of concern was his limitations against left left-handed hitters who batted .293 against him last season. Whitlock’s excellent control (2.09 BB/9), high ground ball rate (49.7) and above average K/9 (9.94) makes him a pitcher who has a good chance at competing for save opportunities working out of the Red Sox bullpen.
