Washington's T.J. Oshie completed his hat trick in overtime to give the Capitals a 4-3 win against Pittsburgh Thursday in a classic start to their NHL second-round playoff series. The Capitals snatched victory in a series billed as a clash between star players Alex Ovechkin of Washington and Pittsburgh's Sidney Crosby in their first playoff showdown for seven years, but instead it was Oshie that stole the show. "That's kind of the stuff you dream about when you're a kid playing in the backyard by yourself is scoring the OT winner and getting a hat trick," Oshie said. "It was awesome. Great way to win." Oshie's wraparound just barely crossed the goal line against the right pad of Pittsburgh goaltender Matt Murray 9:33 into overtime. The call on the ice was a goal, and the video replay confirmed that the puck was completely over the line. Murray, who made 31 saves but was beaten three times by Oshie and once by Andre Burakovsky, wasn't convinced. "The ref called it a goal on the ice," Murray said. "I don't know how he could have possibly seen it from his angle. But I thought I had it, to be honest. I knew it was close, but I thought it never fully crossed the line. I thought it was close enough that it would be inconclusive." Ben Lovejoy, Evgeni Malkin and Nick Bonino scored for Pittsburgh, which will try to even the best-of-seven series Saturday in Game 2. It will be hard to match the entertainment value that was on display in Game 1. Beyond Murray stopping Ovechkin on two breakaways, and Braden Holtby turning aside 42 of 45 shots, there were goals off the rush, a knee-on-knee hit by Washington's Tom Wilson on Conor Sheary and even Jay Beagle getting a stick stuck between his helmet and visor. Ovechkin assisted on Oshie's second goal but went goalless while Crosby was on the ice for three goals against and won 68 percent of his faceoffs. Oshie, traded from St. Louis to the Capitals last offseason, won for the first time in the playoffs when scoring a goal. This was a huge stage for him to step up on, especially because Washington acquired him to win in the playoffs.
