The best photos from the week in sports: May 4 - 11

If you missed any of this week's excitement in the world of sports, fear not -- we have it all rounded up for you here.

Both the NBA and NHL playoffs were whittled down to four teams this week, with conference finals starting in both leagues this weekend. While the Boston Celtics and Houston Rockets hope to topple the Cavaliers and Warriors, respectively, hockey's surprising Vegas Golden Knights lead a group of hockey teams that haven't seen conference finals action in years -- that is, except for the No. 1 Tampa Bay Lightning.

In baseball, the league's two best teams faced off in the Bronx as the Boston Red Sox visited the New York Yankees.

Elsewhere, Tiger Woods and other notable names returned to the green this week, and horse Justify ran his way to winning the 144th Kentucky Derby.

Take a look back at all of these events and more in the gallery above, and be sure to check back next weekend for our selection of the best photos from the coming week's action.
