Brighton's winless run extended to a sixth game after they were held to a goalless draw by a resilient Hull at the Amex Stadium.
Goalkeepers Casper Ankergren and Adriano Basso were the men in form in an entertainng game.
Nigel Pearson's Tigers, who have now gone seven games without defeat, remain in the play-off places.
Striker Craig Mackail-Smith, with five league goals, had several chances but could not make the breakthrough.
Former Spain international Vicente had the best two early chances for the Seagulls, the best a powerful volley which was blocked.
As the highly energetic first period came to a close, Ashley Barnes was left red-faced when he stubbed wide of goal from close range after accurate service from Gary Dicker.
A lack of discipline from Corry Evans allowed Vicente another chance to demonstrate his dangerous ability from setpieces, but the home crowd groaned as his curved free-kick dipped agonisingly over.
Encouraged by a return to attacking manoeuvres, Seagulls boss Gus Poyet harried his players to push forward.
But, with barely 10 minutes remaining, Sparrow looped a cross over the Hull backline to a waiting Barnes, who scooped his shot wide of the target.
The pressure increased on the visitors when Mackail-Smith forced Adriano Basso to punch the ball over with five minutes remaining, Lewis Dunk appearing to block a late Aaron Mclean drive, but the points were shared.
VIEW FROM THE DRESSING ROOM
Brighton manager Gus Poyet told BBC Sussex:
"A great game of Championship football. For fans I know it is better to be 4-4. For us, I can tell you it is better 0-0. We needed a clean sheet because we have conceded too many goals.
"At the end of the day, we are still in a good position. If we compete like today we are going to win football games.
"We had a few shots. Their keeper did well and Casper Ankergren did well for us."
