It’s hard to tell what was the greatest sports performance of the Fourth of July weekend.

There were many to choose from.

So, I will grade them on the fireworks scale before declaring a winner:

-- Serena Williams beat older sister Venus for the Wimbledon women’s champions.

Three Sparklers: Serena won the VENUS Rosewater Dish. Hello, The trophy she won was named Venus. If that isn’t rubbing it in, I don’t know what is.

-- Albert Pujols hit his fourth grand slam of the season Friday night.

Four Firecrackers: Pujols now has 31 home runs and 82 RBI in 83 games. In the post-steroid era (we think), those are some huge numbers.

-- Tiger Woods wins again.

One Smoke Bomb: Woods won his own tournament by one stroke over a field of virtual nobodies. Beat Jimmy Fallon in 18 holes of Tiger Woods 10 on the Wii, Tiger, then we can talk.

-- Ron Artest joins the L.A. Lakers.

Two Roman Candles: Artest was pretty quiet in Houston this year, but get him under the bright lights of L.A. and who knows what kind of fireworks he will produce.

-- Roger Federer outlasts Andy Roddick for the Wimbledon men’s final.

15 High Compression Shells: It was a match for the ages. It took 30 games in the final set to finally decide the thing. Federer finally broke Roddick’s serve to win his record-setting 15th grand slam event.

I was more tired than Federer and Roddick after watching the match than they appeared to be.

And finally ...

Joey Chestnut wins third straight hot-dog eating contest.

68 Molotov Cocktails (and 68 Tums): Chestnut gobbled down 68 dogs in 10 minutes. This weekend, I managed about that many, but it took three days.

Hats off to you, Joey Chestnut, and your iron belly.
