Blues’ Vladimir Tarasenko out 5 months with shoulder injury

Semyon Varlamov stopped 27 shots and the New York Islanders opened their best-of-five playoff series with a 2-1 win over the Florida Panthers on Saturday in the NHL’s return following a 4 1/2-month break. Anthony Beauvillier scored the decisive goal on a power play at 3:39 of the second period. The goal was scored a little over a minute after Florida’s Mike Matheson was penalized for a hit to the head on defenseman Johnny Boychuk, who did not return.
