SAN FRANCISCO — Jaylen Brown fueled a comeback charge and scored 24 points, Al Horford hit six 3-pointers and the Boston Celtics rode the most lopsided fourth quarter in NBA Finals history to a 120-108 victory over the Golden State Warriors in Game 1 on Thursday night. Horford finished with 26 points and the Celtics outscored the Warriors 40-16 in the final 12 minutes after trailing by 15 points late in the third quarter. Boston made its first seven tries from long distance in the fourth and wound up 9 of 12 beyond the arc over the final 12 minutes as almost everybody got involved in the 3-point flurry.
