MESA, Ariz. -- The Arizona House of Representatives on Thursday approved a Spring Training ticket surcharge plan designed to keep the Cubs in Mesa and generate more than $100 million for improvements to facilities across the Valley over the next 30 years.

Arizona Rep. John McComish, R-Phoenix, is pushing the surcharge in House Bill 2736, despite opposition from the other Cactus League teams.

The original plan would raise $81 million over 25 years and included a $1 car rental fee and an 8 percent Spring Training ticket surcharge. McComish dropped the car rental fee and boosted the ticket surcharge to 10 percent in hopes of raising $185 million over 30 years.

The House approved the bill on Thursday, but McComish left the percentage blank so it can be negotiated when the bill goes to the Senate. A 10 percent surcharge would add about $2 to the price of an average $20 Spring Training ticket.

The Cubs are considering a move to Florida if they cannot get assistance in building an $84 million complex in east Mesa. The team's new facility would receive about $58 million from the surcharge. The Cubs are the top draw in the Cactus League and a Mesa study shows they bring $138 million annually to the local economy.

On Thursday, the Cubs-Dodgers game at Camelback Ranch in Glendale drew a Cactus League record 13,391 fans. The previous Cactus League single-game high was 13,366 set March 12, 2004, in Peoria between the Cubs and Mariners. Nine of the top 10 Cactus League attendance figures have been Cubs games.
