PORTLAND — Jim O’Brien scored 25 seconds into the game as the Binghamton Senators ended the Calder Cup playoff run of the Portland Pirates with a 3-0 win Friday night at the Cumberland County Civic Center.

Zack Smith scored a second-period goal and Kaspars Daugavins added an empty-net goal as the Senators avoided a seventh game in the best-of-seven Atlantic Division finals.

Binghamton will play either the Charlotte Checkers or Wilkes-Barre/Scranton Penguins in the Eastern Conference finals.
