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