Stakelum first appeared on the inter-county scene with
Tipperary in 1945, as
captain of the
minor team that won the
Munster MHC title after a 32–point win over
Clare. He subsequently captained Tipperary to a defeat by
Dublin in the
1945 All-Ireland MHC final. After immediately progressing to the
junior team, Stakelum made his
senior team debut in 1947. Success at club level resulted in him being appointed
team captain for the 1949 season. That year, Stakelum was part of the Tipperary side that won the
National Hurling League, as well as the
Munster SHC title after a 1–16 to 2–10 win over
Limerick. He captained the team from wing-back when Tipperary later beat
Laois by 3–11 to 0–03 in the
1949 All-Ireland SHC final. The following year, Stakelum, who was now moved to centre-back, won a second consecutive National League medal. He later won a second consecutive Munster SHC medal, following a 2–17 to 3–11 win over
Cork. Stakelum ended the year by claiming a second consecutive
All-Ireland SHC medal, following Tipperary's a one-point win over
Kilkenny in the
1950 All-Ireland SHC final. Stakelum claimed a third successive Munster SHC medal in 1951, as Cork were once again beaten in the final. He later won a third successive All-Ireland SHC medal, again lining out at centre-back, in the 7–07 to 3–09 win over
Wexford in the
1951 All-Ireland SHC final. Stakelum won further National League honours in 1952, 1954, 1955 and 1957, before retiring from inter-county hurling in 1958. ==Inter-provincial career==
