Formula One championship leader Sebastian Vettel is cautious about the prospects of Red Bull continuing its dominance at this weekend's Korean Grand Prix, saying the layout of the circuit does not suit the car's strengths.

Vettel leads Ferrari's Fernando Alonso in the drivers' championship by 60 points with six races remaining, and while that margin could shrink with a couple of bad races, the dominant nature of the German's victories in the past three races suggests the remainder of the season will be little more than an extended coronation.

Pau Gasol politely stepped out of the paint when Andrew Bynum emerged as a dominant NBA center for the Los Angeles Lakers. The seven-foot-Spaniard stayed in a complementary role when Dwight Howard joined the club for one crazy season.

With Bynum in Cleveland and Howard now in Houston, Gasol is eager to be the Lakers' man in the middle again.
