Horvath is perhaps best remembered for his time playing on the famous "Uke Line" with the Boston Bruins, with fellow Ukrainian-Canadians Johnny Bucyk and Vic Stasiuk. Horvath missed out on the Art Ross Trophy in 1959–60 by a single point to Bobby Hull, however he tied with Hull for the goal-scoring lead, with 39. He played for five of the Original Six teams in the NHL (only missing Detroit), He did apprentice with the Edmonton Flyers, Detroit's WHL farm team, along with John Bucyk & Vic Stasiuk, his future Uke Linemates. He was demoted to the minors in 1963.
