Rookie forward Marcus Sorensen, who was called up Monday from the San Jose Barracuda of the American Hockey League, will play his third NHL game, adding speed to the fourth line that likely will match up against Boyle. Goaltender Martin Jones will make his 52nd start of the season and face rookie Auston Matthews, who has 30 goals and 54 points. "He's unbelievable," forward Mikkel Boedker said. "We've got to watch out for him. At the same time, we can make sure if we turn some of the pucks over and go the other way that he has to play defense and force him to play defense." Marner has 48 points, third among NHL rookies. "Dynamic young players," coach Peter DeBoer said. "I can't remember in my time in the League, which is getting close to the last decade, young guys coming in and making this type of impact." First-line center Joe Thornton needs two assists to become the 13th player in NHL history with 1,000. After a four-game assist streak, Thornton has gone two straight games without one. The Sharks (79 points) enter Tuesday five points ahead of the Anaheim Ducks and Edmonton Oilers for first place in the Pacific Division.
