tRA is a baseball statistic used to measure the performance of a pitcher. Similar to FIP, tRA uses a mathematical formula to isolate the pitcher from his defense. Thus, tRA is a defense-independent pitching statistic. Unlike FIP and dERA, however, tRA takes into account batted ball type (that is, line drives, fly balls, pop ups, and ground balls) as well as strikeouts, walks, and home runs.
