It was tough to see a friend leave, but Martin Frk might get a better chance to make an impact out of Tomas Tatar’s trade. Tatar and Frk were good friends, and for Frk, it was disappointing to see his friend get traded Monday to the Vegas Golden Knights. But Tatar’s leaving left a void in the lineup that Frk filled Tuesday, after being a healthy scratch for five of the last six games. “It’s sad, we lost a good player,” said Frk of Tatar, who was traded Monday for three future draft picks. “He was a great guy in the room as well. It’s a little hard. We’ll miss goals and everything. “But in an opposite way, it’s good to get back in the lineup and hopefully I can produce and help the team win games.” Frk was slated to play alongside Luke Glendening and David Booth Tuesday against St. Louis, along with being on the second power play unit, where Frk was switched from the half-wall to a position near the slot. Declining confidence was one reason coach Jeff Blashill pulled Frk out of the lineup.
