Charles John Grimm, nicknamed "Jolly Cholly", was an American professional baseball player and manager. He played in Major League Baseball as a first baseman, most notably for the Chicago Cubs; he was also a sometime radio sports commentator, and a popular goodwill ambassador for baseball. He played for the Pittsburgh Pirates early in his career, but was traded to the Cubs in 1925 and worked mostly for the Cubs for the rest of his career. Born in St. Louis, Missouri, to parents of German extraction, Grimm was known for being outgoing and chatty, even singing old-fashioned songs while accompanying himself on a left-handed banjo. Grimm is one of a select few to have played and managed in 2,000 games each.

Arley Wilbur Cooper was an American starting pitcher in Major League Baseball who played most of his career for the Pittsburgh Pirates. A four-time winner of 20 games in the early 1920s, he was the first National League left-hander to win 200 games. He established NL records for left-handers – second only to Eddie Plank among all southpaws – for career wins (216), innings pitched and games started (405); all were broken within several years by Eppa Rixey. His career earned run average of 2.89 is also the lowest of any left-hander with at least 3000 innings in the NL. He still holds the Pirates franchise records for career victories (202) and complete games (263); he also set club records, since broken, for innings (3201), strikeouts (1191), and games pitched (469).
