The best photos from the week in sports: March 23 - March 30

While March Madness nears its end, excitement around the rest of the sports world is just beginning.

America's Pasttime returned to our hearts and homes this week as the MLB observed its earliest-ever Opening Day. For the first time in history, all 30 teams were scheduled to play -- but rain caused the postponement of several games.

Elsewhere in the U.S. and Canada, NBA continued the push for the playoffs, which will begin in April.

Tennis, golf and rugby also captivated fans around the globe.

Click through the slideshow above to see photos from all of these events and more, and be sure to check back next weekend for our selection of the best shots from the coming week's action.
