Cardinals manager Billy Southworth used Musial as a left fielder to begin 1942, sometimes lifting him for a pinch-hitter against left-handed pitching. Musial was hitting .315 by late June, as the Cardinals resumed battling the Dodgers for first place in the National League (NL). The Cardinals took sole possession of first place on September 13, and when Musial caught a fly ball to end the first game of a doubleheader on September 27 they clinched the pennant with their 105th win. He finished the season with a .315 batting average and 72 runs batted in (RBI) in 140 games. Musial received national publicity when he was named by "St. Louis Post-Dispatch" sports editor J. Roy Stockton as his choice for Rookie of the Year in a "Saturday Evening Post" article.
