WASHINGTON, April 21 (Xinhua) -- Boston Celtics followed up their 3-0 lead with a 110-106 victory at Indiana, reaching the second round of Eastern Conference playoffs.

The Celtics completed a first-round NBA playoff sweep of hosts Pacers, which is also their first 4-0 sweep since 2011, becoming the first team to reach the second round of the playoffs.

Gordon Hayward shone with team-high 20 points and Marcus Morris added 18 and grabbed eight rebounds. Although Bojan Bogdanovic scored 22 points and Tyreke Evans reached a playoff career-high of 21 to lead the Pacers, Indiana failed to avoid its second first-round sweep in past three years.

The Celtics made a fantastic 8-0 start at the beginning of the first quarter, but the Pacers responded quickly with a 10-point offense. Boston seemed to run away with the game twice in the first half, but the Pacers caught up to gain a 49-47 lead before halftime and extended it to 56-49 in the third quarter.

In the fourth quarter, Boston continued their offense as Jayson Tatum took advantage by making both free throws to win the Celtics an 83-82 lead. Morris and Hayward contributed two 3-pointers with 5:08 and 4:24 left to ensure an 102-90 lead. Eventually, the Celtics defeated the Pacers 110-106.
