If you build it they will come, as the old saying goes. If you pour $100 million into an old building the fans better come, otherwise you’ll find yourself in a ravine full of debt.If you’re the Dodgers, they’re coming — and coming back in record numbers.Dodger Stadium led Major League Baseball in attendance last season with an average of 46,216 per game. Season-ticket sales were capped just short of 32,000. The renovation project — not to mention the expensive product on the field — seemed to be paying off.David Siegel, the Dodgers’ vice president of ticket sales, couldn’t believe his eyes when 98 percent of 2013 season-ticket holders renewed their plans. Siegel believes the investments in infrastructure are having a direct result on demand.“I think it goes to show that the investments our owners have made on and off the field, whether it’s the stadium renovations, to what I think is the best promo calendar in sports, to the product on the field, is getting a lot of traction,” he said.A large renovation project doesn’t pay for itself. The cost of individual tickets on Opening Day and for “four-star games” rose in the vast majority of sections. The most expensive seat in the house, in the front row behind home plate, rose from $160 to $210 for Opening Day and starts at $110 for “one-star games.”The cheapest ticket one can buy — a top-row seat in a “one-star game” — rose from $8 to $10. A handful of seats are cheaper across the board and a few stayed the same; seats in the all-you-can-eat section will remain $30, for example.The four-, three-, two-, and one-star classification system also remains in place. Siegel said fans appreciated the transparency of the system, which replaced the more confusing variable-pricing format of years past.There’s one change. A game’s rating might change based on demand, a twist on the popular “dynamic pricing” system used by many teams.“If a game is trending particularly poorly, if we have a lot of available seats in a particular price category, we could lower the star,” Siegel said. “It could go from a two-star to a one-star. If a game is trending through the roof, it could move from a two to a three.“It’s a hybrid of variable and dynamic pricing.”Because of the dynamic pricing system, the Dodgers can’t say with certainty how much the average cost of a ticket has changed until the end of the season. Based on the early returns, demand (and ticket prices) are on the rise.The effects of new owners on the Dodgers’ player payroll are well documented. Guggenheim Baseball Management — a group including Kasten, chairman Mark Walter and Magic Johnson — has signed off on more than a billion dollars in player contracts since purchasing the team in April 2012. That includes contracts the Dodgers acquired via trade.What’s been the biggest change in the ticket sales department?“I think it comes down to the investment in the fan experience,” Siegel said, “whether you’re a season-ticket holder or individual-ticket buyer.” Newsroom GuidelinesNews TipsContact UsReport an Error “In a good year, a low 90 percent (renewal rate), teams are throwing parties,” Siegel said. “In tougher years, it’s a lot lower than that. For the Dodgers, a very good year would be in the 90-to-91-percent range.”As a result of the mass renewals, Siegel said the Dodgers had to cut off season-ticket sales for the coming season. More than 31,000 season tickets have already been sold. The team might choose to release more seats, but Siegel said that’s yet to be determined.“We’re currently re-evaluating how we can launch in very short order,” he said.The annual select-a-seat event for season ticket holders began Wednesday, and the team’s annual FanFest is Saturday at Dodger Stadium. More than half of the 40-man roster, and prominent alumni like Ron Cey, Fernando Valenzuela and Orel Hershiser, are scheduled to sign autographs.Fans will also get an early look at the construction behind the left- and right-field bullpens. Two bars, restaurants and concession stands are being added to a long list of stadium enhancements that were rolled out last year. Team president Stan Kasten expects a long-awaited wifi network to be in place by Opening Day.
