Whitham made his debut for Wednesday on 6 May 1967 as a substitute against his home town club Burnley and scored twice in a 7–0 victory. Whitham's time as a Wednesday player was marred by injury problems; his brave style of play meant that he spent long periods on the treatment table and he never played 20 league games in any season. He scored 10 goals in 10 games at the start of the 1968–69 season but never scored again that season as injury took its toll. He still ended up as top scorer that season; his tally included a hat-trick against Manchester United in a memorable 5–4 win on 31 August 1968 which was the highlight of his time at Hillsborough. In the following 1969–70 season he was top scorer again with 11 goals in all competitions as Wednesday were relegated to Division Two. In April 1970 he was transferred to Liverpool for a sum of £57,000. In his time with Wednesday he scored 31 goals in 62 starts, an excellent record of a goal every other match.
Liverpool
Whitham was signed by Liverpool as a potential replacement for Roger Hunt who had left to join Bolton Wanderers in December 1969. However, his injury problems continued and he failed to get an extended run in the team. The arrival of John Toshack at Anfield in November 1970 further hindered his chances of first team football. He did well towards the end of 1971 when he scored two late goals in an away win at Coventry City and then scoring a hat-trick in a home 3–2 win against Derby County on 11 December 1971. In four years he would play just 15 games for Liverpool, scoring seven goals.
Later career
Whitham joined Cardiff City for the 1974–75 season, after being invited to a trial by then manager Frank O'Farrell, scoring three goals in 14 appearances before moving to Reading for the following season making 19 appearances as they were promoted from Division Four, his three goals that season all came in the same match against Hartlepool United. Whitham returned to non-League football in 1976 playing for Worksop Town, Hallam F.C. and then Oughtibridge in the local Sheffield league He then went to Hallam as manager before retiring.

He then became the manager of the South Yorkshire PoliceSocial Club at Wadsley Bridge. From 1993 until 2007 Whitham was a part-time scout for Sunderland FC and in 2007 he joined Luton Town as Chief Scout. After Luton Town went into administration in early 2008 Whitham went to Wolverhampton Wanderers for a short spell before becoming head of player recruitment at Sheffield United.
