EL (16-3) will play No. 6 Skowhegan (12-7) in Wednesday’s semifinals. Skowhegan upset No. 3 Mt. Blue of Farmington 56-55 in overtime in the earlier game of the late afternoon quarterfinal session.
Hampden Academy, the 2011 Eastern A champion, ends its season with a 10-9 record.
EL took a 31-14 halftime lead, but Hampden’s Jordan Maxwell went 5-for-5 from beyond the 3-point arc during the third quarter to help rally the Broncos to within two points on two different occasions.
But Edward Little scored the final six points of the period — four by Arnold on a 3-pointer and a free throw — to extend its lead back to 45-37, and Harriman made two 3-pointers and went 4-for-4 from the line in the fourth quarter to help the Red Eddies preserve their lead.
Maxwell finished with 22 points for Hampden, while Ashley Danforth added 18.
