Patrick Sharp had a goal and an assist, and Patrick Kane broke a tie late in the second period in the Chicago Blackhawks' 2-1 victory over the Detroit Red Wings 2-1 on Sunday.
Ray Emery made 23 saves to help Chicago solidify its hold on the sixth playoff spot in the Western Conference.
Niklas Kronwall scored for Detroit, 27-4-2 at home. Jimmy Howard made four saves before leaving after the first period because of a lower-body injury. Joey MacDonald stopped 12 shots in the final two periods.
Red Wings defenseman Jakub Kindl also left early in the first period because of an upper-body injury. Detroit already was without captain Nicklas Lidstrom, center Pavel Datsyuk and defenseman Jonathan Ericsson.
Lidstrom missed his third game because of a deep bone bruise in his right ankle and is expected to sit out at least one more game. Datsyuk is recovering from arthroscopic surgery on his right knee, and Ericsson has a broken left wrist.
RANGERS 4, BRUINS 3
At New York, Derek Stepan and Marian Gaborik scored in the third period as New York held on to beat Boston for the fifth straight time.
Gaborik gave the Rangers a 3-2 lead 3:14 into the third with his 32nd goal, but David Krejci tied it for Boston at 11:42. The Bruins barely had time to celebrate before Stepan ripped a drive from the left circle that sailed goalie Tim Thomas and under the crossbar 39 seconds later.
The Rangers opened a 12-point lead over the defending Stanley Cup champion Bruins in the Eastern Conference playoff race. New York's closest pursuer is Atlantic Division-rival Pittsburgh, which is 10 points behind.
Anton Stralman and Carl Hagelin also scored for the Rangers, and Henrik Lundqvist made 30 saves.
ISLANDERS 1, DEVILS 0
At Uniondale, New York, Anders Nilsson made 24 saves to become the first Islanders goalie to have a shutout in his first NHL victory, leading New York past New Jersey.
The 21-year-old Nilsson was called up from Bridgeport on Feb. 29. He was selected the AHL goalie of the month for February after going 6-0-1. The 6-foot-5 Swede made his first NHL start Nov. 21, losing 5-0 at Pittsburgh. He also played the last two periods in a 6-0 home loss against Boston on Nov. 19.
Kyle Okposo scored early in the second period.
