Despite scoring the first goal for only the second time this year, the Phantoms dropped another to the Senators, 5-2.
Sean Couturier put the Phantoms on the board just 1:24 into the game, but the Senators responded with their first of two two-goal minutes.
Derek Grant scored at 7:30 and Tyler Eckford added another 27 seconds later. Binghamton held onto the 2-1 lead going into the first intermission, which Phantoms head coach Terry Murray has said is even more crucial than scoring the first goal.
Ben Holmstrom came out and tied it up in the second period. Brayden Schenn hit the post with a shot from the left circle and Holmstrom scored on the rebound. After a lengthy review, it was a 2-2 tie 9:19 into the second period.
The Senators responded again, this time only 1:17 later. Pat Cannone scored from the right circle and then Mike Zibanijad made it a two-goal game just 57 seconds later.
Things got interesting in the final minutes of the second period. Harry Zolnierczyk took a big hit from Mark Borowiecki and was slow to get up, though he did return to the game later. No penalty was called, but shortly after that a brawl broke out.
Tyler Brown and Grant started it off and everyone else quickly paired off. In the end, three Phantoms and three Senators were given game misconducts in addition to the fighting major for being involved in secondary altercations. Marc-Andre Bourdon, Garrett Roe and Mike Testwuide were sent off for the Phantoms as were Eckford, Frederik Claesson and David Dziurzynski for the Senators.
Zolnierczyk had the best chance of the third period, with a breakaway early in the frame. He was pulled down, again by Borowiecki, and the Phantoms couldn't score on the resulting power play.
The Phantoms did not score on any of their three power plays and held the Senators without a goal in five opportunities.
Binghamton tallied one more goal as Mark Stone scored an empty-netter with 19 seconds to play.
