The Blackhawks have acquired Rob Scuderi in a trade with the Pittsburgh Penguins for fellow defenseman Trevor Daley.
The 36-year-old Scuderi has four assists and 32 blocked shots in 25 games with Pittsburgh this season. He has eight goals and 96 assists in 745 games over 12 NHL seasons with Pittsburgh and Los Angeles.
Scuderi also won the Stanley Cup in 2009 with the Penguins and 2012 with the Kings.
Daley, 32, was acquired by Chicago in the July trade that sent Patrick Sharp to Dallas. He had six assists in 29 games with the Blackhawks.
Daley made his NHL debut with the Stars in 2003 and has 67 goals and 170 assists in 785 games over 12 seasons.
>>Caps Blast Penguins
T.J. Oshie scored twice and added an assist as Washington spoiled Sullivan's debut with a 4-1 win on Monday night. The victory propelled the Capitals into the top spot in the Eastern Conference standings and 11 points clear of their struggling rivals.
Nicklas Backstrom added a goal and two assists for Washington. John Carlson scored his fifth of the season and Braden Holtby stopped 44 of Pittsburgh's season-high 45 shots.
Evgeni Malkin scored his team-leading 14th goal and Marc-Andre Fleury made 30 saves, but the Penguins failed to keep pace with Washington in the team's first game since firing Mike Johnston on Saturday.
Washington is off to the best start in the franchise's 41-year history by finding a way to both take advantage of Alex Ovechkin's dynamic offensive play while also paying attention to detail at the other end of the ice.
