When the Clippers hit the 70-point mark in the first half Friday against the Lakers, it was a runaway.

When they did it Wednesday against Dallas at Staples Center, they almost had company.

Then the runaway happened, and the Clippers were on the wrong end of it but somehow escaped with a 129-127 win.

Jamal Crawford hit two free throws with 11.2 seconds left to give the Clippers a 128-127 lead, then Dirk Nowitzki inexplicably passed up a shot at the end and the Clippers captured their fourth straight victory and will take that on their seven-game road trip.

The Clippers took a 100-98 lead into the fourth quarter but they couldn’t shake the Mavericks, who turned Nowitzki loose and took advantage each time the Clippers turned inattentive.

Nowitzki scored 27 points and the Mavericks used a 32-8 run to steamroll the Clippers, who stormed back and got a 3-pointer from J.J. Redick with 34 seconds left to pull within a point.

Redick scored 23 of his career-high 33 points in the first half.

Matt Barnes had 25 points and hit five 3-pointers and Blake Griffin had 23 points, seven rebounds and eight assists for the Clippers, who halted the Mavericks’ three-game win streak.

Samuel Dalambert added 20 points for Dallas, which had six players reach double figures.

Dallas worked the Clippers early for 16 second-chance points in the first quarter, though the Clippers shored it up in the second quarter, pitched a shutout in that category and took a 72-62 halftime lead.

Along the way, Redick hit 6 of 8 3-point tries and scored 23 points in the first two quarters. Griffin then began to take over after taking only four shots in the first half. He scored nine of his 20 points in the third quarter.

It was a game the Clippers wanted maybe a bit more than most, because it would serve as the launching pad into a seven-game, 11-day road trip to the East that begins Friday in New York.
