The San Jose Sharks finished up the preseason schedule on Saturday night against the Utah Mammoth in Salt Lake City, and for most of the first period, it looked like they really didn’t want to be there. The Sharks, though, could not slow down the Mammoth in the third period, allowing goals to Clayton Keller and Brandon Tanev in a 6-4 loss at the Delta Center. The Sharks were outshot 11-3 in the third period, and starting goalie Yaroslav Askarov stopped 17 of 23 shots. The Sharks dressed mostly an NHL-caliber lineup in their final tune-up before the start of the regular season on Thursday at home against the Vegas Golden Knights. Celebrini and Smith were on the same line for several games last year and lined up with Kurashev during a recent practice.
