Stamkos called his team's performance unacceptable.
"It was absolutely not acceptable, especially at this time of year," Stamkos said.
"Look, people watched that game tonight (yesterday) and probably think the series is over. But our group, we're a very resilient group. So whether it's one-zero or seven-zero or 10-zero, we have to step up as a team and as individuals. Let's go home to our fans and see what we're made of."
