Recap: Boston vs. Dallas

Boston, MA (Sports Network) - Paul Pierce scored 34 points and the Boston Celtics needed two overtimes to beat the Dallas Mavericks, 117-115, on Wednesday.

Rajon Rondo added 16 points, 15 assists and nine rebounds for the Celtics, who have won two in a row. Kevin Garnett and Jeff Green tallied 16 and 15 points, respectively.

"I didn't like our shots down the stretch, but overall we got a lot of good shots," Celtics head coach Doc Rivers said. "They just weren't going in. So we won a game where the team we played shot 51 percent, and we shot 43 percent. That was happening to us earlier in the year, where we lost a couple of games where we shot the exact opposite."

O.J. Mayo ended with 24 points to pace the Mavericks, who had a three-game winning streak snapped. Darren Collison donated 20 points and Shawn Marion had 16 points and 11 boards.

"We had plenty of opportunities to take control of that game and win," Mayo said.

Trailing by 14, 68-54, with 4:57 left in the third quarter, Dallas went on a 12-4 run to get back in the game. Collison tallied seven points during the surge, including a layup with 1:43 remaining to cut the gap to 72-68.

Rondo made a pair of jumpers around Collison's jumper to give Boston a 76-70 edge heading to the fourth.

Dallas kept it close in the fourth frame and took the lead, 95-94, on Derek Fisher's 3-pointer with 1:47 to go.

Pierce responded with a 16-foot jumper to put the Celtics back in front. At the other end, Fisher was off the mark with a floater. Marion and Pierce battled for the rebound underneath, with the ball going out off Pierce.

Consecutive fouls on Garnett and Rondo sent Mayo to the foul line, where he made 1-of-2 to tie the game with 52.1 seconds left.

Dallas called a timeout after Pierce missed a jumper. The Celtics had a chance to win the game following Rondo's steal, but Fisher blocked Rondo's jumper.

With the score tied at 101 late in the first overtime, Jason Terry stripped the ball from Collison. Terry missed a layup at the other end, but Boston kept the ball due to a loose ball foul on Fisher.
