There are so many sports every weekend that it can be nearly impossible to keep track of them all. Here is a weekly guide to the five games/events/experiences that you will be in danger of missing if you make the mistake of going outside.

1. The NCAA Tournament keeps on truckin'. Counterintuitively, the second round of the NCAA Tournament offers, to some, less excitement than the first two days. It should be a bigger deal: These are now teams playing for a trip to the Sweet 16, for the chance to be two wins away from the Final Four. These are teams that have already won a game, so there isn't a single dog in the bunch. And there are fewer games going on at once, which means you can actually sit and concentrate on each of them. Though I wonder if that's part of the problem. The first two games on Saturday, here in Buffalo where I'm at all weekend, will both be played before another game begins, which means you better hope that Notre Dame-West Virginia and Villanova-Wisconsin are compelling, or the third day of the tournament will have four hours you can easily ignore. When it comes to the first weekend of the tournament, sometimes it really is the quantity, not the quality. Anyway, that Notre Dame-West Virginia game kicks us off at 12:10 ET on Saturday on CBS.

2. A rematch of powerhouses at the World Baseball Classic. While Japan and the Netherlands have already reached the semifinals of the WBC, over here in the Americas we're still battling it out. The second matchup of the United States and the Dominican Republic is at 7 p.m. ET on Saturday on MLB Network and MLB.TV (ESPN Deportes in Spanish).

The U.S.'s loss to Puerto Rico on Friday made this game particularly massive: Puerto Rico is now on to the semifinals, so Team USA vs. the D.R is an elimination game. It doesn't get any bigger than that.

3. Are the Red Bulls for real? Only four teams -- the New York Red Bulls, Portland, Houston and San Jose -- have won both their games to start the MLS season, but the Red Bulls are already turning some heads, winning at Atlanta United's emotional opener and pulling out a workmanlike 1-0 victory over Colorado. Sunday night, though, they get the defending MLS Cup champion Seattle Sounders at 7 p.m. ET Sunday on FS1. The Sounders are off to a slow start, and it's also worth keeping a close eye on Clint Dempsey, who is not only recovering from an injury but is also on the USMNT roster for a massive World Cup qualifier on March 24. Even if you're a Red Bulls fan, you want him to look fit: The Americans need him.

4. UConn's ride for yet another title begins. The Women's NCAA Tournament tipped off on Friday, but even with all the storylines, there's still only one major one: Will Connecticut keep their 107-game win streak going all the way to another championship? They begin their journey against poor Albany at 11:05 a.m. ET on Saturday on ESPN2. Only three games of those 107 have been won by fewer than 10 points. Do not expect this to be the fourth.

5. More 'gators at the Arnold Palmer? The PGA TOUR is still warming itself up to The Masters in three weeks, and the Arnold Palmer Invitational at Bay Hill cruises on NBC and the Golf Channel all weekend, complete with tributes to the late legend (#ArnoldWould). But no matter what happens, nothing's going to be more exciting than Cody Gribble goosing an alligator.

Let Gribble's goose be your goose into an active weekend. Get going, America!
