McGuire appeared in more major league seasons than any catcher in baseball history – 26. He caught 1,611 games, most coming during the 19th century. He reached his peak with the National League Washington club, topping the .300 mark each year from 1894 through 1897, and never again. At a time when pinch hitters were rarely used, he was a good one (14-for-41 lifetime). Though he managed in six different years, only the 1910 Indians were his for an entire season, and he never had a winning record.
