Water is expensive, at least if you’re spraying it at opposing players.

The NHL’s Department of Player Safety handed out $5,000 fines to New York Rangers center Kevin Hayes and Tampa Bay Lightning forwards Steven Stamkos and Alex Killorn, all for unsportsmanlike conduct from Thursday’s game.

Hayes kicked things off with an aquatic assault from the Rangers’ bench, squirting Killorn with his water bottle. Killorn gave a retaliatory stick jab.

Stamkos sought some revenge of his own, spraying in the direction of the Rangers’ bench.

Killorn picked up a minor for slashing, with the conflict also setting off a fight between New York’s Steven Kampfer and Tampa’s J.T. Brown.

“Basically, the ice was pretty dry, so I wanted to get it wet,” said Hayes.

Former NHL tough guy Kelly Chase was not pleased:

“Boys will be boys,” offered Rangers’ coach Alain Vigneault.

From the NHL:
