Tampa's Adam Vosding is a huge Lightning fan, and when he was in Las Vegas for a weekend in September, days before the season started, he put $100 down on 10-to-1 odds for Tampa Bay winning the Stanley Cup.That didn't pan out, but he wasn't done that day. He saw the odds on Las Vegas' expansion team winning it all — 200-to-1 at the time — and decided it was worth a $100 long shot as well. Now the Golden Knights are in the Stanley Cup final against the Washington Capitals, and Vosding is three wins away from a $20,000 payday."I figured it was worth throwing $100 down on them to win, too," said Vosding, 40, who said he knew Vegas had a strong goalie in Marc-Andre Fleury going into the season.Vosding, who works in commercial property management, has been a Lightning season-ticket holder for 10 years and even manages a few road games each season, going to Colorado, Montreal and Ottawa this year. When the Olympics were in Sochi, Russia, in 2014, he was there in Lightning gear, cheering on Martin St. Louis.Until last week, when the Lightning lost to the Capitals in the Eastern final, it looked like Vosding might have winning tickets for both remaining teams. A Lightning-Knights final would have created a dilemma of sorts, either a win-win or a lose-lose."I hate to say it would have been a bad situation for me, because obviously having a ticket that's going to win something would be good, but I could never root against my Lightning," he said.Vegas, which was a 5oo-to-1 shot for some hopeful bettors, won the series opener against Washington on Monday, but the Capitals won 3-2 on Wednesday to even the series."I'm trying not to fret it too much," he said. "Nobody's won anything yet, but I'm pulling for Vegas, for sure."
