Input: Question: When did the player who opened the scoring in York's first match first join the team? Passage:York's first match was away to last season's League Two play-off finalists, Wycombe Wanderers, which they lost 3–0. Anthony Stewart opened the scoring with a header before Aaron Amadi-Holloway scored from a low shot, and Zubar scored an own goal when his attempted back-pass lobbed Flinders. York then played League One team Bradford City at home in the first round of the League Cup, and the visitors took the lead in the first half through a Christopher Routis volley. Luke Summerfield equalised with a penalty in the 49th minute, and after Bradford missed a penalty 20 minutes from time, Berrett scored a free kick in the 85th minute. James Hanson headed an equaliser for Bradford in stoppage time, and the match ended 2–2 after extra time. York won the penalty shoot-out 4–2, and Flinders saved two penalties before Carson scored the winning spot kick. York lost 2–1 to Hartlepool United in their first home league match of the season, despite taking the lead in the 57th minute when Thompson scored after Hartlepool failed to clear Summerfield's cross. Billy Paynter curled a shot into the top corner before Michael Woods scored the winner for Hartlepool in the 81st minute, after his miskicked shot took a touch off Berrett.
