Right-winger Don O'Donoghue played 125 games for the Oakland/California Seals. Most of his pro career was spent in the WHA and the minors where he was a fast skater and solid checker who could chip in with a few goals.
The native of Kingston, Ontario played two years of junior with the OHA's St. Catharines Black Hawks. He was chosen 29th overall by the Seals in 1969 and played 68 games an NHL rookie in 1969-70. He was an effective defensive forward playing on a line with Brian Perry and Howie Menard. He split the next season between the woeful Seals and the AHL's Providence Reds.
By 1971-72, O'Dongahue was relegated to farmhand status for California. Prior to the 1972-73 season he decided to join the WHA's Philadelphia Blazers where he scored 16 goals. The hard working forward remained with the franchise when it relocated to Vancouver then suited up briefly with the Cincinnati Stingers in 1975-76. O'Dongahue retired in 1978 after nearly three full years in the SHL and AHL with the Hampton Gulls.
