BOSTON (AP) — Ray Allen picked the perfect time to snap out of his shooting slump.

Allen made a tiebreaking 3-pointer with 2 seconds left and finished with 30 points, leading the Boston Celtics a 118-115 win over the Chicago Bulls in Game 2 of their playoff series Monday night.

Ben Gordon nearly carried Chicago to a 2-0 lead in the best-of-seven series. He scored with 12.3 seconds left to tie it, and had a playoff career-high 42 points. Then Boston set up a play for Allen, who took a pass from Rajon Rondo and connected from the right side.

Allen had just four points on 1-for-12 shooting in Boston’s 105-103 overtime loss on Saturday.

The next two games of the series are scheduled for Chicago on Thursday night and Sunday.

Spurs 105, Mavericks 84

SAN ANTONIO (AP) — Tony Parker had 38 points and eight assists to help the Spurs beat the Mavericks in Game 2 of their first-round playoff series.

Dallas was trying to send the Spurs to consecutive home playoff losses for the first time since 2002, but couldn’t contain San Antonio’s speedy point guard. Parker had 27 points in the first half.

Jason Terry finished with 16 points for Dallas, which suffered one of the worst losses in the playoff rivalry.

Game 3 is Thursday in Dallas.

The Mavericks beat the Spurs 105-97 on Saturday night for their first road playoff victory in three years. But it was hardly rare territory for San Antonio: The Spurs have come back to win four series after losing Game 1 since 2002.

They put together a convincing response in the second game and the frustration for Dallas could be seen all the way down its bench. Mavs owner Mark Cuban punched a water cooler as San Antonio pulled away in the fourth.

The Mavericks haven’t won a playoff series since 2006. Winning the opener was a start, but they’ll have to figure out another way to stop Parker in Game 3.

Parker finished 16-of-22 from the field. He had 19 points in the first quarter alone, equaling the Mavericks’ total.
