On this day, we think racecars, but there's another world of racing! (Hal Wood Photo)

Mercedes' Nico Rosberg -- who just happens to live up the street from where they will be running Sunday's Monaco's Grand Prix -- made it a perfect weekend so far as he took all three practice sessions . . . and won the pole position ahead of teammate Lewis Hamilton and Red Bull's Sebastian Vettel.

For the past decade, the winner has always come from the first three starters . . . Red Bull's Mark Webber starts on Sunday in fourth.

Trivia: As you probably know, Keke Rosberg is Nico's dad, and the dad never won a pole at Monaco.

Oh, it's also Nico's third straight pole this season.

See Formula One from Monaco on NBC Sports Sunday at 7:30 a.m. (Eastern).

In Cup practice on Saturday it was the three K's at the top, Kasey, Kurt and Kyle . . ..

Kyle Busch didn't have the pole for Saturday's History 300 at Charlotte Motor Speedway, but it didn't matter. After the first lap he was in the lead, and in all he led 186 of the 200 laps for a dominating win, his sixth in nine Nationwide races this year.

Kyle broke the record for wins by Mark Martin in Nationwide racing, and he fell just short of Dale Earnhardt's leading 194 of 200 laps on a 1.5-mile racetrack. Kasey Kahne was close in the final restarts, but he couldn't get past Kyle and finished second, back about nine-tenths of a second, while third went to Joey Logano.

Of course, it's going to be a long Sunday of racing in Monaco, in Indianapolis and Charlotte with Formula One's Monaco Grand Prix, the Indianapolis 500 and the Coca-Cola 600 -- all traditional Memorial Weekend races.

Before the Indy 500, there's a one-hour Indy 500 pre-race program, and then the race itself at noon, being shown on ABC for the 49th consecutive year. Here, Ed Carpenter has the pole and will share the front row with Venezuelan wonder kid Carlos Munoz, a rookie, while on the outside will be Marco Andretti. The first 10 drivers are using Chevy engines, and Honda comes in 11th with Alex Tagliani.

But wait a minute: On Friday during Carb Day, Simon Pagenaud, who had qualified his Honda-powered car on the seventh row, was suddenly fastest . . . were those Honda drivers sandbagging? We're hoping they were so there won't a a Chevy steamroller.

NASCAR's A.J. Allmendinger (yes, he was named for A.J. Foyt, his dad's favorite racer) will start fifth at the Brickyard. Two three-time winners, seeking to make their names immortal, are Helio Castroneves and Dario Franchitti. Helio starts eighth, while Dario, the defending champion, starts 17th and has Honda power.

And, not to beat a dead stock car, the Coca-Cola 600 goes off in Charlotte with pre-race commentary starting at 5:30 on FOX.

On Thursday night the final track record in a cascade of records was set by Joe Gibbs Racing's Denny Hamlin with an astounding 195.221 mph in his Toyota, followed by Kurt Bush in his Chevy at 194.595 mph.

On Sunday night they run the Coca-Cola 600 at Charlotte Motor Speedway. You can see the green flag fall at 6:16 p.m. (Eastern) on FOX. See the full starting order in the Racing News Section.
