It's becoming an all-too familiar story.
Tuesday night the Edmonton Oilers started well enough, then made a late charge, but were unable to overcome another bad second period.
The middle frame has been the Oilers nemesis all season, and it hurt them again against the Anaheim Ducks, conceding three goals - two on the power play - en route to a 5-3 loss.
"It's frustrating and tough to explain," said Oilers centre Kyle Brodziak. "We got into a bit of penalty trouble and they capitalized on it. That's pretty much what it comes down to.
"We had a great push back in the third, but when you're down three goals, you can only do so much."
Heading into the contest, the Oilers have been out-shot by a margin of 227 and out-scored 87-74 in the middle frame.
The Oilers went into the second tied 1-1, but were unable to kill off a late first-period too-many-men penalty.
"Obviously taking a couple of penalties really hurt us," Gilbert said. "They have a great power play. That second period hurt us, we didn't apply as much pressure as we wanted to.
"Unfortunately for us, it's cost us a lot of games. It's something we want to clean up and something we have to fight through."
The Oilers current predicament can be attributed to the struggles in the second period. As has been the case all year, they outscored their opponents in the third period after playing them even in the first.
The Oilers had conceded just four more goals than they had scored in the first period this season, but had also outscored their opponents in the third.
"I don't know why we've struggled0 in the second period, but it's definitely been a problem spot for us," said Oilers captain Ethan Moreau. "I don't know why that happens or what you can attribute that to. I don't have a good answer for that."
