continued to fall short in the field in those two years. Detroit manager Hughie Jennings made him the Tigers' starting first baseman, and he led the league in errors at that position both years, including 31 in 1919 for a .979 fielding percentage. Heilmann was married on October 5, 1920, to Mary H. Maynes, commonly known as Mae. They had a daughter, Mary Ellen, and a son, Harry, Jr., and lived in Detroit. 1921 season In 1921, Heilmann appeared in 149 games, including 145 as the Tigers' starting right fielder. He won his first batting title, compiling a .394 batting average to outpace his manager and teammate Ty Cobb who hit .389. Unofficial figures released in October showed Cobb as the batting champion, but official figures released in December showed Heilmann to be the champion. He was the first right-handed batter to win the American League batting title since Nap Lajoie in 1905. Heilmann also led the American League in 1921 with 237 hits and ranked second behind Babe Ruth with 139 RBIs, 365 total bases, a .606 slugging percentage, 292 times on base, a 7.3 offensive wins above replacement (WAR) rating, and 159 runs created. He also ranked among the league leaders with a .444 on-base percentage (third behind Ruth and Cobb), 43 doubles (third behind Tris Speaker and Ruth), and 76 extra base hits (third behind Ruth and Bob Meusel). Heilmann's batting average in 1921 was 85 points higher than his 1920 average and 101 points higher than his career average prior to 1921. Some attributed Heilmann's dramatic improvement to the tutelage of Ty Cobb, who took over as the Tigers' manager in 1921. Others attributed Heilmann's improvement to the "live-ball era" that started in 1920 and forced outfielders to spread out and play deeper, allowing more of Heilmann's line drives to fall into the wider gaps. However, Frank G. Menke attributed his improvement to having learned the game, noting that the "lively ball" failed to account for the fact that those who outhit Heilmann from 1914 to 1920 were no longer outhitting him. Menke observed: There is nothing picturesque, nothing highly colored, nothing bombastic or spectacular about his methods. He is not a grandstander -- not theatrical. And because he isn't, he does not get the acclaim and the plaudits which men, less wonderful, but better showmen, achieve for themselves. Though primarily a line-drive hitter, Heilmann could
