A boxing superfight, the biggest horse racing event of the year, some much-needed football and, oh yeah, a couple of playoff games? That's not a dream for a sports fanatic, but a reality that will happen Saturday. Floyd Mayweather vs. Manny Pacquiao is expected to shatter all sorts of records while everyone will be tuning in for the Kentucky Derby while sipping on some mint juleps. You can root for your team's future during the third day of the NFL Draft 2015, or watch NBA or NHL playoff games. There's even baseball and soccer thrown in for good measure.

Even if you don't care about sports, you have to appreciate how big Saturday will be in terms of economic and cultural impact. It's a cosmic alignment that will have millions of eyes glued to televisions or at the actual events. There are some interesting matchups in baseball -- including Yankees vs. Red Sox, Tigers vs. Royals and Mets vs. Nationals -- while the Rangers play the Capitals in the second round of the NHL playoffs. Saturday could also see a pair of Game 7s -- Bulls vs. Bucks and Clippers vs. Spurs -- in the NBA. Those events serve as the undercard to Mayweather vs. Pacquiao, a fight that has been in the works for seven years.
