Bulls 142, Nets 134

Brooklyn blew a 14-point lead late in regulation and lost to host Chicago in triple overtime Saturday, leaving the Nets in a 3-1 hole in the first round of the playoffs.

“Definitely a heartbreaker,” Joe Johnson said.

The Nets were leading 109-95 in the closing minutes of the fourth quarter when Nate Robinson went on one of his tears and carried Chicago to the wild victory. The streaky guard finished with 34 points.

The next challenge for Brooklyn is avoiding elimination when the series shifts back to Barclays Center for Game 5 on Monday. The Nets are going to have to dig deep to win three in a row after they wasted a prime chance to draw even and steal back home-court advantage.

“Frustrated. Upset,” Deron Williams said. “Tired. Lot of emotions.”

Robinson scored all but five of his points after the third quarter, including the first 12 in a 14-0 run that wiped out Brooklyn’s late lead. Then with two seconds left in the first overtime, he banked in a go-ahead jumper over Williams.

Johnson answered with one of his own to send it to another overtime, tied at 121. The Bulls had a chance to win in the closing seconds of the second extra session, but Joakim Noah was blocked, and the game went to a third overtime.

The Bulls finally pulled away after Williams (32 points) drove for a layup to pull Brooklyn to 133-130 with three minutes left. The basket accounted for Williams’ only points after regulation.

Luol Deng then scored to make it a five-point game, and Nazr Mohammed hit two shots in the final 32 seconds to help preserve the win.
