[1] Roth attended Strathcona Academy and, in his free time, compiled statistics for his hometown Montreal Royals of the International League.

He worked in the unit charged with organizing reinforcement contingents for Canadian Forces in Europe, where he managed all the records and statistics.

[1] In 1944, Roth met with Branch Rickey, who had replaced MacPhail as the general manager of the Dodgers, sending him a four-page letter contained proposals to track a wide range of statistics.

[3] After Rickey departed from the Dodgers, new owner Walter O'Malley moved Roth to the press and public relations operation.

[1] Initially working from behind home plate, Roth was moved to the radio booth in 1954 where he provided statistics and facts to broadcasters.

[4] After the Dodgers moved to Los Angeles, Roth began to attend spring training in Vero Beach, Florida.

Future Hall of Fame pitcher Sandy Koufax credited Roth with helping him turn around his career through these sessions.

[1] Roth was fired by the Dodgers during the 1964 season after it was discovered that he was having an extramarital affair with an African-American woman, when the two had a fight in the corridor of a Philadelphia hotel.

O'Malley disliked controversy and, as interracial relationships were frowned upon at the time, the press were told that Roth had resigned because he was tired of travelling.

[5] The Society of American Baseball Research (SABR) named their Los Angeles chapter in his honor, where he was often attended meetings and showed his new workings during the offseasons.
