Richardson’s layup lifts Heat past Jazz

MIAMI — Josh Richardson’s layup with 5.1 seconds left capped a Miami rally from eight points down in the fourth, Donovan Mitchell missed what would have been the winner at the buzzer and the Heat beat the Utah Jazz 103-102 on Sunday.

Tyler Johnson and Goran Dragic each scored 16 points for Miami, which has won four straight — all by single digits, the Heat’s longest stretch of such games since November 2012.

Richardson and Hassan Whiteside each had 14 points, James Johnson scored 13 and Kelly Olynyk had 12.

Mitchell scored 19 of his 27 points in the second half, but couldn’t save Utah from dropping its seventh straight on the road. He went into the backcourt to take the final inbounds pass and wound up taking a jumper from the right side that missed as time expired.

Rodney Hood scored 17 points, Thabo Sefolosha added 13 and Derrick Favors 11 for the Jazz. Utah was up eight with 6:59 left, and was still up by five in the final 2 minutes before Miami closed on an 8-2 spurt.

Richardson’s winner came after the Heat called a timeout with 7.8 seconds left, after corralling the rebound off of Hood’s miss. Richardson got to the rim with ease, laid it in and Miami moved back to fifth in the Eastern Conference.

Kristaps Porzingis scored 29 points and Jarrett Jack made the tiebreaking basket with 31.2 seconds left as the New York Knicks beat the Dallas Mavericks. Kyle O’Quinn had 15 points and 11 rebounds, and Enes Kanter added 13 points and 18 boards for the Knicks, who ended a three-game losing streak and sent the Mavericks to their third straight loss — all at home. Harrison Barnes scored 25 points and Devin Harris had nine of his 11 in the fourth quarter as the Mavericks made yet another rally on the night they honored their long-time point guard Derek Harper by retiring his jersey. Dallas never led in the game, and after coming up just short in furious fourth-quarter rallies against Golden State and Chicago earlier in their homestand, the Mavericks made another run after falling behind 90-77 with 4:48 to go. Harris hit 3-pointers to start and end a 15-2 run over a 2:20 span to tie the score at 92. After Porzingis made two free throws and Barnes hit a short jumper, Jack used a screen to penetrate into the lane and drop in a floater. J.J. Barea missed a long 3 that would have given Dallas the lead, and Courtney Lee hit four free throws in the final 16.6 seconds to seal it. Kanter and Porzingis combined for 24 points in the first half. The man who helped make the Dallas Mavericks relevant in the NBA in a short period of time was immortalized Sunday night at halftime of the Dallas Mavericks game against the New York Knicks at the American Airlines Center. Point guard Derek Harper, who wore jersey No. 12 for 12 of his 17 seasons in the NBA, had his number retired to the rafters alongside teammates Rolando Blackman and Brad Davis. Harper’s style and production was a key reason Dallas was able to quickly ascend to elite status in the NBA after beginning play as an expansion team in 1980.
