(REUTERS) - Stephen Curry scored 17 of his 40 points in overtime as the Golden State Warriors rallied for a 132-125 victory over the Portland Trail Blazers at the Moda Centre on Monday.

The Warriors grabbed a 3-1 lead in the National Basketball Association Western Conference semi-final series.

Curry, coming back after missing the previous four play-off games with a sprained right knee, came off the bench to score 27 of his points in the fourth quarter and extra session. He also had nine rebounds and eight assists.

The Warriors trailed 16-2 before the reigning league Most Valuable Player came off the bench midway through the first quarter.

Klay Thompson scored 23 points and Draymond Green collected 21 points, nine rebounds, seven blocked shots and five assists for the Warriors.

Damian Lillard scored 36 points and handed out 10 assists, C.J. McCollum added 24 points, and Al-Farouq Aminu chipped in 18 points and 13 rebounds for the Blazers, who will try to extend the best-of-seven series by winning Game 5 at the Oracle Arena on Wednesday night.

Curry scored the champions' first 12 points of overtime for a 123-118 lead with 1min 51sec to go. Harrison Barnes' fast-break lay-up extended the lead to 125-118 with 1:23 to play.

Lillard made a pair at the line to reduce the gap to 120-125 with 1:18 to go, but Curry buried another three-pointer, and it was 128-120 with 1:05 remaining. The Blazers got no closer than seven points the rest of the way.

Both teams shots poorly in the first half, Portland 39.6 and Golden State 39.1 per cent, but improved to close at 40.6 and 46.3 per cent respectively.
