Input: Question: Which of the two teams  Hayes played against for the Combined Universities team has won the most championships? Passage:Hayes made his first-class debut for Lancashire against Oxford University in 1980. This was his only appearance for the county that season. The following year, Hayes began his university studies at the University of Oxford, making his first-class cricket debut for Oxford University against Gloucestershire at the University Parks, scoring a half century on debut. He made five first-class appearances for the university in 1981, including The University Match at Lord's Cricket Ground where he made another half century. His List A debut came in this season when he appeared twice for a Combined Universities team in the Benson & Hedges Cup against Somerset and Essex. He also made two further first-class appearances that season for Lancashire, against the touring Sri Lankans and Worcestershire in the County Championship, as well as a single List A appearance for the county in the John Player League against Worcestershire. Ten further first-class appearances for Oxford University followed in 1982, with Hayes scoring what would be his only century for the university against Warwickshire, with a score of 152. In what was his most successful season in first-class cricket in terms of runs, Hayes also made three first-class appearances for Lancashire, with his thirteen first-class matches in that season bringing him a total of 594 runs at an average of 31.26, with a high score of 152. In one-day cricket, Hayes made four appearances for the Combined Universities in the Benson & Hedges Cup, as well as appearing once for Lancashire in the John Player Special League.
