Watching the Washington Capitals will cost more next season.

The Capitals announced yesterday that the prices of season tickets for the 1983-84 season will rise to $13.50, $11.50 and $7.50, and that individual game tickets will cost $14.50, $12.50 and $8.

This season, single game and season tickets are $12.50, $10.50 and $7 per seat.

"Inflation" was cited as the reason for the increase.

According to Lew Strudler, the Capitals' marketing director, season ticket prices were set slightly lower than those for single games "as an incentive to the person who's buying 40 games.

"In the past, maybe we have penalized the season ticket holder by offering single game discounts," he said. By "rewarding" season ticket buyers, he said, the Capitals hope to increase those sales, now about 5,500.

In 1981-82, Capitals' tickets cost $11, $9 and $6.

Strudler said the price increases were announced now partly "to show people the continuity of the program, to show that the Capitals will be in town next season." Last summer, ticket prices remained as much a mystery as the Capitals' status.

But now that they are a playoff-bound team, the Capitals also announced first- and second-round playoff ticket prices of $15.50, $13.50 and $9. Tickets will go on sale during the Vancouver game March 23. A deposit of $100 per seat on 1983-84 season tickets will guarantee playoff tickets.

Defenseman Brian Engblom, hit by a puck over his left eye March 2, began skating with the team again yesterday. He is expected to play in Saturday's game on Long Island.

Scott Stevens, who hyperextended his right elbow in last week's victory over the New York Rangers, and Craig Laughlin, who separated his right shoulder March 2, were examined by doctors yesterday. Laughlin was ruled out of Saturday's game, Stevens was listed as possible.
