Penguins team scope

The Pittsburgh Penguins added depth to their defense prior to the NHL Trade Deadline on Wednesday, acquiring Mark Streit from the Tampa Bay Lightning and Frank Corrado from the Toronto Maple Leafs. "He's obviously a veteran guy," coach Mike Sullivan said of Streit. "He's played in the League a long time. He brings a puck-moving ability to his game, we can use him on the power play. Mark's a good player. With some of the injuries we have, I think [the front office] was looking to try to improve our depth on defense, so that we have the best chance to succeed moving forward." Pittsburgh is tied with the Columbus Blue Jackets in the Metropolitan Division, seven points behind the Washington Capitals for first in the division and Eastern Conference. The Penguins are looking to salvage a split of a back-to-back set that began with a 3-2 loss at the Dallas Stars on Tuesday. Defenseman Kris Letang will miss his third straight game with an upper-body injury. Goalie Marc-Andre Fleury will start. Defenseman Derrick Pouliot was recalled from Wilkes-Barre/Scranton of the American Hockey League. The 23-year-old is expected to draw into the lineup.

Blackhawks team scope

Defenseman Johnny Oduya, reacquired by the Chicago Blackhawks in a trade with the Dallas Stars on Tuesday, will not play but could be in the lineup against the New York Islanders on Friday. Oduya, 35, has played one game since coming off an ankle injury that sidelined him for 15 games, but the Blackhawks will be cautious with him. "We want to make sure he's more than ready when he plays his first game here," coach Joel Quenneville said. "So, he gets in today, get him on the ice, get a better evaluation, see how he is and where he's at." Oduya is expected to form a defense pair with Niklas Hjalmarsson, who will miss his second straight game with an upper-body injury. Hjalmarsson also is out for Chicago's two remaining games this week. Goalie Scott Darling will make his second straight start in place of Corey Crawford, who missed a 4-2 win against the St. Louis Blues on Sunday. Crawford has recovered from his illness, but Quenneville made the decision to go with Darling after he played well against St. Louis. Chicago has won four games in a row and is 9-1-0 in its past 10.
