NBA courts are cleaned meticulously but, apparently, not always with proper cleaning solution. Good thing this mishap occurred only during the preseason. From the AP: “Slippery court conditions forced the cancellation of Friday night’s preseason finale between the Orlando Magic and Miami Heat, after arena officials said an oil-based cleaning solution was mistakenly applied. Some fans reacted angrily, and one Heat player was nearly struck by an object thrown from an upper deck of the arena while the cancellation announcement was made about an hour before the game’s scheduled tip-off. Many Magic players, and most of their equipment, were gone at that point. [...] The court conditions had been a concern for several hours, after the Magic arrived to practice at the arena—which hosted a Tampa Bay Lightning game Thursday night—and found the court was wet and slippery in several spots.”
