NEW YORK (AP) - Myles Cale hit a go-ahead 3-pointer with 9.5 seconds left in overtime and Seton Hall overcame Keldon Johnson's half-court heave that tied the score at the regulation buzzer, stunning No. 9 Kentucky 84-83 on Saturday in a thriller at Madison Square Garden.

In one of the most exciting finishes of the season, Johnson had a chance to win it for the Wildcats (7-2), but his 3-point try with a second remaining was blocked by Quincy McKnight. The ball went out of bounds as time expired, and excited Pirates players rushed off the bench to celebrate a huge win.

Myles Powell scored 22 of his 25 points after halftime for Seton Hall (6-3), including a tiebreaking 3 in the final seconds of the second half.

The clock showed 1.1 seconds after Powell's step-back, double-clutch jumper went through, but officials put 1.5 on the clock after a replay review. That made all the difference for Kentucky when PJ Washington inbounded from the baseline and threw a long pass to an open Johnson. He caught the ball near half court, turned over his left shoulder and hurled a right-handed shot that went in as the buzzer sounded to tie the score at 70.

Washington had a career-high 24 points and finished with 12 rebounds for Kentucky, which had won seven straight since a 118-84 blowout loss to Duke in the season opener Nov. 6.
