Early minor league career (1905, 1908–1911)

In 1905, Kuhn joined the minor league Fresno California League club. On that team, he played with former, and future major league players Frank Chance, Roy Hitt, Pete Lohman, Judge Nagle, and Jud Smith.^[3] Kuhn's statistics for that season were not kept. For the next two seasons (1907–08), Kuhn would not appear in professional baseball. He returned in 1908 with the minor league San Francisco Orphans, and Fresno Tigers of the independent California League. Combined between the two teams, he batted .264 with 23 hits in 29 games played.

In 1909, Kuhn re-signed with the Fresno club, who changed their name to the Raisin Growers.^[4] During the season, his contract was sold to the Minneapolis Millers of the Class-A American Association.^[5] However, he was farmed out to the Fresno club for the remainder of the season.^[5] Kuhn batted .258 with 119 hits, 23 hits, 23 doubles, and seven home runs in 134 games played. He finished the season tied for fourth in doubles, and tied for fifth in home runs.^[6] After the season, it was reported that the Major League Baseball (MLB) New York Highlanders were interested in purchasing Kuhn for the price of US$2,000.^[5] However, New York failed to reach an agreement with Fresno.^[7]

Kuhn again played with the Fresno California League team in 1910, who changed their name back to the Tigers.^[7][8] In February 1911, Kuhn signed with the Portland Beavers of the Class-A Pacific Coast League.^[9] During the final game of the Pacific Coast League Pennant Series, Kuhn hit a home run in the bottom of the ninth inning to give the Beavers the win.^[10] On the season with Portland, he batted .228 with 79 hits, 11 doubles, four triples, and two home runs in 120 games played.

Chicago White Sox (1912–1914)

In February 1912, Kuhn signed with the MLB Chicago White Sox.^[11] He attended spring training with the White Sox that season.^[11] Billy Sullivan, Chicago's starting catcher at the time, stated that Kuhn would be a successful major league player.^[12] Kuhn made his MLB debut on April 18, 1912, against the St. Louis Browns.^[13] In August, Kuhn was given the job of starting catcher for the White Sox.^[14] In his first major league season, he batted .202 with 16 runs scored, 36 hits, seven doubles, 10 runs batted in (RBIs), and four stolen bases in 76 games played. He finished the season fifth in the American League in defensive games as a catcher (75); and tied for fifth with Eddie Ainsmith, Oscar Stanage, and Ed Sweeney in passed balls (9).^[15]

At the start of the 1913 season, Kuhn was given the Chicago White Sox's starting catcher job.^[16] In August, he lost his starting job to the White Sox new catcher, Ray Schalk.^[17] Towards the end of the season, Kuhn injured his arm, which caused him to miss playing time.^[18] With Chicago that season, Kuhn batted .160 with five runs scored, eight hits, one doubles, and five RBIs in 26 games played. After the season, he stated that he wanted to return to the Pacific Coast League and play with the San Francisco Seals.^[18]

Kuhn re-signed with the Chicago White Sox in February 1914, despite his previous statement in which he said he would like to return to the Pacific Coast League.^[19] In March, during a spring training game, Kuhn seriously injured his right hand.^[20] It was reported that he would not be able to resume playing with the White Sox until the start of the season.^[20] The hand injury was later described as a cracked right index finger.^[21] In July, it was reported that Kuhn was traded to the Milwaukee Brewers in exchange for Larry Chappell.^[22] However, Kuhn played with the White Sox for the entire season. His last MLB appearance would come on September 28, 1914. On the season, he batted .275 with four runs scored, 11 hits, one double, and two RBIs in 17 games played.
