Early Doors provided trainer Joseph O'Brien with a second winner of the week and a much-needed tonic after the tragic loss of Sir Erec earlier in the day with victory in the closing Martin Pipe Handicap Hurdle.
The topweight, who finished third in this race last year, looked booked for second up the home straight besides the looming favourite Dallas Des Pictons, but ultimately found more under pressure for Jonjo O'Neill jnr.
Hazel Hill was produced with a perfectly-timed run by Alex Edwards to win the St. James's Place Foxhunter Challenge Cup Open Hunters' Chase.
A prolific winner in point-to-point company, Hazel Hill was sent off the 7-2 favourite for trainer Philip Rowley and a spring-heeled leap at the last sealed victory in the amateurs' event.
Croco Bay provided another shock success as he lifted the Johnny Henderson Grand Annual Challenge Cup Handicap Chase at odds of 66-1.
Trained by Ben Case and ridden by Kielan Woods, Croco Bay had only run once since finishing fifth in this race two years ago.
However, his lack of match practice did not show as he galloped all over his rivals and held off the challenge of Bun Doran to take the Grade Three prize.
