Extreme Rules was a professional wrestling pay-per-view (PPV) event produced by World Wrestling Entertainment (WWE) for their Raw and SmackDown brand divisions. It took place on April 25, 2010, at the 1st Mariner Arena in Baltimore, Maryland. It was the second event promoted under the Extreme Rules name but the first to feature the aptly named Extreme Rules match. There were eight matches scheduled on the event's card, all of which featured a hardcore stipulation, with no regular singles matches on the card. The event received 182,000 pay-per-view buys, the same as the figure achieved by the 2009 Backlash event. Extreme Rules 2010 also replaced Backlash as the post-WrestleMania pay-per-view.
